How to Open a Laundry Coin Box With Lost Key

One of the most common issues with coin-operated laundry is opening a laundry coin box with a lost key. A laundromat’s coin box is thick enough to withstand amateur attempts to unlock it.

But here is our solution to ensure you collect your coins and your tenants can use your laundromat even when you lose the keys.

The Importance of Coin-op Laundry Boxes

At the end of the day, we want to ensure that these coins are always collected for you, the landlord. Now there’s an actual key, like many locks, that ensures it goes in and out.

These coin boxes, as you can see, are built really thick, and they are meant not to be drilled. That way, residents can’t drill them, illegally take the coins, and have an issue. If you’ve ever lost the key or, even worse, had it stolen, you might be tempted to drill out the lock to gain access. However, drilling a laundry coin box isn’t just difficult—it’s extremely time-consuming and, frankly, not the route you want to take unless you absolutely have no other choice. The boxes are specifically designed to withstand brute-force attempts, which is great for security but a headache if you’re locked out yourself.
If you find yourself standing in front of a locked coin box with no key, don’t panic. There are safer ways to attempt access before resorting to the drill. First, always unplug the washer or dryer for safety—it’s easy to forget when you’re frustrated, but electricity and metal tools don’t mix.

Next, locate the locking mechanism, which is usually a cam lock at the front of the coin box. Sometimes, with a bit of finesse, a flathead screwdriver or a lock-picking tool can gently turn the lock cylinder, especially if it’s an older unit. Take your time and don’t force it—damaging the lock may make things much harder down the line.

If gentle persuasion doesn’t work, you can try carefully prying the lock cover, but avoid damaging the coin box or surrounding panels. Only as a last resort should you consider drilling out the lock cylinder, knowing that these boxes are specifically designed to resist just that.

Remember, the goal isn’t just to get to the coins, but to keep the equipment in service for everyone and avoid costly repairs.

Opening a Laundry Coin Box Without the Key

One of our biggest issues is when these keys get lost. But the cool thing is if you look at the key’s back and front, there is a little code, its serial number.

We have learned to take note of this serial number, such as by taking a picture or writing it down. Using this code, you can avoid drilling the box if you lose the keys.

In addition, we ensure that if we take over a building and there is a set of keys, taking note of the serial numbers will be one of the first things we do. 

There are instances where we have taken over a building, and the person doesn’t have the key to the coin box. If we can figure out the serial number, we can order the keys without avoiding the box.

Do You Really Need to Break Open the Coin Vault?

A lot of people wonder if cracking open the coin vault is the only way to get to your hard-earned quarters when you’re missing the key. The short answer: in most cases, you don’t need to destroy the box—there are usually better ways.

Instead of reaching straight for the drill or hammer, first check for a serial number or any documentation with a replacement code. If you can track that down, reaching out to the manufacturer or a locksmith is usually your best bet. Most major companies, like ESD or Greenwald, can send you a replacement key if you provide the right code—saving you a major headache and your coin vault from unnecessary damage.

That said, if the serial number is worn off or missing, and all other options are exhausted, only then would forced entry be your last resort. But in almost every scenario, we recommend trying the route of ordering a replacement key or calling a professional locksmith first. It’ll save you money on repairs and maintain the integrity of your machines.

How to Identify the Right Master Key for Your Coin-Op Washing Machine

So, how do you figure out which master key you’ll need for your coin box? The answer lies in the numbers etched on your key or right on the lock itself, typically a series like “777” or something similar.

These numbers aren’t random—they correspond to the specific key type for your lock. If you jot down or photograph this code, you can match it to the key you’ll need. For example, if you see “777” on several machines, that indicates those units can use a matching “777” key.

If your machines have different numbers, it means they each require a unique key, unless you choose to switch all the locks so they’re keyed alike. In that case, universal locks (like the ESD or Greenwald 777 series) are available and can save you hassle in the future.

In short:

• Look for a stamped number on your key or lock cylinder.
• Match this number with the replacement key or lock set from a laundry supply vendor.
• Consider standardizing to one lock style if you have multiple codes—future-you will thank you.

Once you know the number, ordering a replacement or universal master key is straightforward, and you’ll avoid unnecessary locksmith visits or drills to the lock.

What If the Key Is Stuck or the Lock Won’t Turn?

If you find yourself standing in front of a stubborn coin box with a key that simply refuses to budge, don’t panic. This issue pops up more often than you’d think, especially with older machines or locks that haven’t seen a drop of lubricant in years.

Here’s what usually works for us:

• Apply a lubricant: Start by using a graphite lock lubricant or a silicone spray (WD-40 can work in a pinch, but try to avoid oils that collect dust). Spray a tiny amount directly into the keyhole and carefully wiggle the key. Sometimes, the simplest fix does the trick.
• Gently tap the lock: Take the handle of your screwdriver or a small rubber mallet and gently tap around the lock while trying the key. This can help free up any stuck pins.
• Avoid forcing it: Don’t use excessive force or you might break the key inside the lock—which is its own headache to fix!

If you still can’t get the lock to turn, it may be time to call a professional locksmith who’s familiar with commercial laundry or vending machine locks. Sometimes, that bit of expertise is worth every penny to save your time—and the coin box.

What If You Don’t Have the Key Code?

So, what happens if you’ve lost your coin box key and don’t have that crucial code handy? Here’s the reality: Replacement keys can only be ordered if you have the correct key code. Without it, things get tricky.

If your key isn’t marked or you can’t locate the code anywhere—say, on old invoices or paperwork—your options narrow down quickly. Sometimes, checking with the company that supplied your machines might help, but many manufacturers and distributors don’t keep open records tied to individual locations for security reasons. Don’t count on simply calling them up and saying, “Remember the key you sent us years ago?”—it just doesn’t work that way.

It’s also important to know that serial numbers or model numbers stamped on the machines don’t usually match up with the actual key code. Even if you find those numbers, they won’t get you a working replacement key unless you have the real code from the lock itself.

If all else fails, and you can’t track down the code, you’ll be looking at the last resort: drilling out the lock and replacing it entirely. And that’s not just a hassle—it’s an expense you’ll want to avoid.

What if Your Laundry Key is Unmarked and You Don’t Have the Code?

Sometimes, you’ll come across a coin box key that’s unmarked—no serial number, no handy code to reference, just a mystery key from keys-gone-by. If that happens, don’t panic. There are still a couple of things you can try:

• Search Old Records: Check any existing documentation, invoices, or building paperwork. Sometimes, previous owners or property managers made a note of the key code somewhere in the paperwork.
• Contact the Distributor or Manufacturer: Reach out to the company that supplied the laundry machines—companies like Greenwald, ESD, or Cobra frequently keep records of lock codes tied to machine serial numbers.
• Ask the Previous Owner or Management: If you recently took over the building, previous management might have the code information or a contact who does.

By doing a bit of detective work, you can often track down the missing code without resorting to more drastic measures like drilling the box open. Keeping organized records from the beginning just saves you from this headache down the road.

What You Need to Order a Replacement Key

When you’re ready to order a replacement key for your laundry coin box, make sure you have the correct key code on hand. This code is not the same as the model or serial number you might find elsewhere on the machine, so don’t get those confused. The actual key code is usually stamped somewhere on the original key or sometimes on paperwork from when the box was first purchased.

If the key code isn’t marked or readily available, you might need to search through purchase records or even reach out to the original distributor for help in finding it. Many manufacturers and locksmiths—companies like American Lock, Lucky Line, or local locksmith shops—will require that code to create a replacement.

Without the right key code, there aren’t many options other than drilling the lock and installing a new one, which is definitely something we work hard to avoid for our landlords. Keeping an organized record of all your key codes from day one makes the whole process much smoother and saves time and hassle down the road.

Where to Locate the Model Number on a Whirlpool Commercial Dryer

If you’re on the hunt for the model number of your Whirlpool commercial dryer, you’ll usually find it in a couple of common locations. Start by opening the dryer door and checking along the door frame—manufacturers like Whirlpool, Maytag, and Speed Queen typically place the model tag there for easy access. If it’s not inside the door, take a glance at the back panel of the machine or along the cabinet sides, since those spots are also popular hiding places for serial plates.

Sometimes the sticker or tag can get worn or hidden under years of dust, so grab a flashlight and give those areas a close inspection. Jot that number down—just remember, while the model number is handy for ordering parts or checking manuals, it won’t help you source a replacement coin box key unless you also have the lock’s specific key code handy.

How to Drill Through a Coin Box Lock (Without Making a Big Mess)

Alright, let’s say you’re out of options—no key, no code, and no magic solution from old paperwork—and it’s time to get that stubborn coin box open. Before you grab the nearest power tool and let loose, here’s how you can drill out a coin box lock with as little collateral damage as possible (and still look like you know what you’re doing).

• Unplug the Machine: Safety first! Always disconnect the washer or dryer from power before you begin, just in case.
• Mark the Center: Grab a center punch or even a sturdy nail to make a small dent right in the middle of the lock. This keeps your drill bit from sliding around like you’re ice-skating on steel.
• Start Small, Work Up: Begin with a small drill bit—something modest, nothing too ambitious. Slowly and gently drill directly into the center of the lock, then increase your drill bit size gradually. You’re aiming to drill through the lock pins, not the entire door.
• Take Your Time: No need to muscle through—gentle, steady pressure is best. You want to avoid slipping and accidentally scratching (or worse, damaging) the coin box or other machine parts.
• Remove the Lock Core: Once you’ve drilled through enough to release the pins, the core of the lock should come out. You may need a screwdriver or pliers to coax it free.
• Install the New Lock: Slide in your shiny new replacement lock. If you want to spare yourself future frustration, a little graphite lubricant in the keyway goes a long way to keep things moving smoothly.

A gentle touch and patience are your best friends here. And—if you can swing it—try to avoid drilling altogether by keeping great records of your key codes. But if all else fails, now you know how to handle it without turning your laundry room into a hardware store crime scene.

What to Do with Proprietary Laundry Lock Codes

If you find that your lock or key has a special manufacturer code—like those you might see from Maytag, Speed Queen, Huebsch, or Milnor—don’t worry. Manufacturers often use unique codes (for example, some Maytag keys start with “ZB”) that are tied specifically to their machines.

When you run into one of these codes, the best move is to identify and note the serial or code on your lock. Once you have it written down or snapped in a photo, contact the manufacturer or an authorized locksmith who specializes in that particular brand. They’ll be able to help you track down a replacement key or solution.

We’ve seen plenty of these situations—so rest assured, with the code in hand, you’re one call away from a new key, no drilling required.

Are There Master Keys for Laundry Machine Locks?

We get this question a lot: “Can’t I just use a master key for all these round locks and save myself the headache?” It sounds like a handy solution, especially if half your laundry room seems to run on the same style key.

Here’s the scoop. Some lock types—like the round “tubular” keys you’ll find on many service panels—are available in standard versions (e.g., a “777” key that fits certain Greenwald or ESD service doors). If your machines all use the same style and code, one key can, in theory, open all those locks. In practice, though, different machines (even from the same brand) often have unique codes for added security. Unless all your locks are keyed alike, a universal master key that works across different codes simply doesn’t exist.

• For service panels: You may be able to swap all your service panel locks for a single style that uses one key, like the aforementioned “777” round key—but you’ll need to physically change out the existing locks if they don’t already match.
• For coin boxes: These are a different animal. For security, coin box locks are expressly designed not to be opened by a common key. Even if you could get all-new locks, they’d have to be ordered keyed-alike from the manufacturer, and there’s no “skeleton key” for existing coin boxes.

So, if you want true one-key access, you’re looking at a coordinated lock replacement project. Otherwise, master keys aren’t a practical solution for most coin boxes or mismatched locks—record-keeping and careful key management save the day once again.

Where to Get Replacement Keys for Your Laundry Equipment

If you find yourself missing a key and need a replacement for your laundry equipment, it’s important to know where to turn. The process depends on the manufacturer of your coin box or lock.

• For Greenwald keys: Contact Greenwald Industries directly or reach out to one of their authorized distributors.
  • 800-221-0982
  • Fax: 860-526-4250
• For ESD keys: Get in touch with ESD Inc or one of their distributor partners.
  • 800-523-1510
  • Fax: 215-643-4623

Keep in mind, keys are generally only available through the original manufacturer or their distributors for security reasons. If you’re unsure about your lock’s brand, check for a name or logo on the box—this will help you contact the right source and avoid unnecessary hassle.

Can You Get One Master Key for Different Laundry Machine Brands?

If you’ve ever wrestled with a giant ring of keys and wondered, “Isn’t there a simpler way?”—you’re not alone. Many laundry operators dream of trimming down their keychains to just one or two keys for all their coin boxes and service panels. Unfortunately, the reality is a bit less magical.

Here’s the scoop: there’s no universal master key that will open coin boxes or service panels across different brands. Each manufacturer (think Maytag, Speed Queen, Huebsch, Milnor, Greenwald, ESD, and so on) uses their own unique lock and key systems, purposefully designed this way for security.

What are your options if you want to simplify things?

• Standardize Your Locks: If your machines use a mix of locks and key types—especially if you see round keys numbered differently—your best bet is to swap out all the locks within a category (say, all service panels or all coin boxes) for matching ones from the same brand and style. Once every lock in a given group matches, you’ll have a single key for those.
• Service Panel vs. Coin Box Keys: Sometimes, you can match all your service panel locks to use just one key, separate from your coin box keys. For example, if your round service panel locks have the same key number (like “777”), you can order matching locks and use a single key for those panels. The coin boxes, on the other hand, usually require their own unique keyway—so unless you replace every coin box lock as well, you’ll still have at least two keys.
• Master Keys for a Single Brand/Type: Some lock styles offer master keys, but these only work within the same series or manufacturer—and only if all locks are keyed alike. Mixing brands? Sadly, you’re still stuck with multiple keys.

If organizing your key situation sounds daunting, take stock of how many locks and brands you’ve got. Upgrading to matching lock sets now could save you from future fumbles and frustration.

And, as always, keep your key codes and lock numbers handy. Having this info at the ready means replacements or upgrades will be smoother if you decide to standardize in the future.

What to Do If Your New Dryer Arrives Without a Coin Mechanism Key

It happens more often than you’d think: You’ve just unboxed a shiny new commercial dryer for your laundry room, but lo and behold—the all-important key for the coin vault is missing. Before panic (or power tools) sets in, here’s how to get things sorted without unnecessary drama.

• Confirm Which Key Is Missing: Some machines use a different key for setting the timer versus accessing the coin vault itself. Double-check what’s included, and make sure it’s the coin vault key that’s MIA—not just the common time set key.
• Contact the Manufacturer and Dealer: Your first call should be to the dealer where you purchased the machine. If they can’t help, reach out directly to the manufacturer (think Maytag, Speed Queen, Huebsch, Milnor, or Whirlpool itself). Often, you’ll need to provide any codes printed on the existing lock—these may look like “ZB” or similar, depending on the brand.
• Ask About Replacement Policy: Most reputable manufacturers will help you replace the lock and key under warranty if they weren’t included. Sometimes, you may be required to remove the existing lock first before receiving a replacement. If so, verify exactly what’s needed—they may send a technician or furnish clear instructions.
• Consider Professional Help: If you’re told the lock must be removed, but you don’t have a key, a professional locksmith with experience in commercial laundry equipment is your best bet. Let them know about any unique mechanisms or manufacturer-specific security features to prevent a drawn-out process.
• When DIY Is Inevitable: If you need to remove the lock yourself, follow the safe drilling steps outlined earlier: unplug the unit, mark the center, start small and work up, and apply steady pressure until the core comes free. Don’t go straight for brute force—precision wins here, and it’ll make installing the new lock much easier.
• Keep Records for Next Time: Once sorted, jot down (or photograph) your new lock’s code, and keep it on file for future reference. Trust us—you’ll save yourself a headache down the line.

Dealing with missing keys is never fun, but with patience and the right steps, you’ll have your coin vault unlocked and renters back in business before you know it.

Can You Use One Key for All Your Coin Laundry Machines?

If you’re dreaming of a magic “master key” that will open every coin box and service panel across all your washers and dryers—regardless of make and model—here’s the straight answer: it’s (almost) always a no-go.

Manufacturers like Greenwald, ESD, Maytag, Speed Queen, and others each use their own unique lock and key systems as a security measure. This means even if you have two coin boxes side by side, but from different brands, there’s simply no universal key that will open them both. The locks are designed that way on purpose to prevent theft and unauthorized access.

Now, if you own several machines from the same brand, it’s sometimes possible to have them re-keyed so that one key fits all of those locks—but mixing brands puts you right back at square one. Each manufacturer’s lock is crafted to be brand-specific, so unfortunately, simplifying your key ring to just a single key for everything is a locksmith pipe dream.

The best you can do is minimize the number of keys by grouping machines by brand and seeing if you can order matching locks (or have existing ones re-keyed, if available through the manufacturer). That can help a bit—but there’s no magic bullet for total key simplicity when you’re wrangling a multi-brand laundry room.

Drilling the Keyhole vs. Drilling Rivets: Which Is Simpler?

We’re often asked whether it’s easier to drill out the keyhole or the rivets when you just can’t get that stubborn coin box open. From plenty of trial—and a few error-filled afternoons—we can tell you: drilling straight through the keyhole is usually the quicker and less messy route.

Here’s why:

• Less Hassle, Fewer Tools: A sturdy center punch and a 1/2-inch drill bit are just about all you need. Line up the bit right in the center of the keyhole, and you’ll break through the lock core much faster than wrestling with multiple rivets.
• Time-Saver: Drilling out the rivets means tackling several tough spots, which can quickly eat up your afternoon. The keyhole method, on the other hand, usually gets you inside in just a couple of minutes—sometimes less if you’ve got a steady hand.
• Reduced Damage: Prying or hammering at the rivets can crack or dent the box itself, especially on older Greenwald or ESD models. Drilling the keyhole goes right through the lock, minimizing collateral damage.

So when all else fails, save yourself the headache—go for the keyhole. Just be ready to replace the lock after you’re through, and try not to make a habit of it.

The Right Tools for Drilling Out a Coin Box Lock

If you do find yourself at the point where drilling out the lock is your only option, here’s the method that’s worked best for us—and it doesn’t require an entire toolbox or hours of your time.

You’ll want a bull nose center punch, which helps you create a starter dimple right in the middle of the keyhole. This gives your drill bit a clear target and keeps it from slipping around. With that starter divot in place, grab a reliable 1/2-inch drill bit (something made for metal, like the ones you’d find from Irwin or DeWalt work well) and drill straight into the center of the lock.

Usually, the process takes just a minute or two when done properly. The punch helps you breach the key guard, and the properly sized drill bit does most of the heavy lifting—no wrestling or fuss required. Just remember, as always, keep safety goggles handy and go slow and steady.

If You Can’t Get a Replacement Key

We also know how to drill them with special bits, but that’s something we want to avoid. However, if you’re truly stuck—maybe there’s no record of the original key code, the manufacturer is unresponsive, or you’re up against a stubborn proprietary lock—there is a last resort.

Here’s how the pros get it done:

• Use a bull nose center punch to mark the center of the keyhole slot. This helps breach the key guard from the center, making the next step smoother.
• Take a 1/2-inch drill bit and carefully drill into the center of the lock.
• With a steady hand, this process can be completed in just a couple of minutes. The last time I had to do it, it took less than a minute to remove the coin box entirely.

Of course, drilling out a lock means you’ll need to install a replacement lock afterward—so it’s usually a method of last resort. But if all else fails, it’s reassuring to know there’s still a way back in without too much drama.

Why Most Locksmiths Can’t Duplicate Coin Laundry Keys

You might wonder why you can’t just call up your neighborhood locksmith and ask them to make a new key for your coin box, like you would for your mailbox or car. Unfortunately, most coin laundry locks are a different breed.

These locks are designed with unique, restricted keyways—the pathways inside the lock are intentionally tricky and don’t match standard blanks you’d find at places like Home Depot or Ace Hardware. Unlike house or car keys, locksmiths simply don’t have access to the specialized blanks needed to cut most laundry keys.

Tubular locks—those round, vending machine-style locks—are the rare exception. But for the vast majority, if you lose your laundry box key, most locksmiths won’t be able to help you out with a copy.

Can You Use Master Keys for Both Coin Boxes and Service Panels?

It’s a question nearly every laundry operator has asked at some point: is there such a thing as a master key that’ll open both coin boxes and service panels—ideally across multiple brands? If only it were that easy.

Here’s the reality: coin boxes and service panels typically use different types of locks, and even within the same make or model, the odds of a single master key working for everything are slim to none. Most coin boxes are intentionally fitted with high-security or restricted keyways to prevent exactly that kind of universal access. Service panels—on the other hand—sometimes do share a common key type, especially if you’ve got a fleet of machines from the same manufacturer or if the locks are all keyed alike.

But if your washers and dryers come from different brands, you’re generally looking at a mixed bag of locks, each with its own key or keyway. The only way to consolidate down to one or two master keys is to physically change out all the locks to ones that match—or in the case of round, tubular locks, have them all set to use a single code, like 777 or 922. Companies like Greenwald and ESD sell replacement locks and keys specifically for this purpose.

Best case scenario: if you’ve got mostly round (tubular) service panel locks, you may be able to rekey or standardize those for a little less hassle. But for coin boxes, unless you replace every lock with matching hardware, a one-key-fits-all approach just isn’t in the cards.

In short: save the dream of one master key for your front door—laundry locks are a tougher nut to crack.

What to Do If Your Coin Box Key is Stuck or the Lock Won’t Turn

If you find yourself wrestling with a stubborn coin box key that just won’t budge—or worse, it’s stuck in the lock—don’t panic. Before you reach for the drill, try a couple of tricks to free things up:

• First, check for debris: Sometimes lint or a stray coin jammed in the slot can cause resistance. Use a can of compressed air to clear out the keyhole.
• Lubricate with a graphite-based spray: Avoid oily sprays, which can attract more gunk. A little graphite can loosen things up without leaving a sticky mess.
• Gently wiggle the key: Apply steady, gentle pressure—never force the key, as this might snap it off inside the lock.

If the lock still refuses to cooperate, you may be dealing with a worn or damaged lock mechanism. In cases where the lock is beyond saving (and you’ve already confirmed you’re using the correct key), the last resort is to drill out the lock for removal. This involves carefully using a center punch to mark the middle of the keyhole, then drilling into the center with an appropriate-sized bit—usually a 1/2-inch drill bit works well. We recommend proceeding with caution, as drilling can permanently destroy the lock, and replacing it will be necessary afterward.

Remember, keeping a backup key and regular maintenance can save you from most of these headaches. And if you’re ever unsure, don’t hesitate to call in a professional locksmith with experience in commercial laundry equipment—they’ll have the right tools and know-how for a safe and clean fix.

Why Drilling Coin Box Locks Isn’t Always Easy

Now, let’s talk about the “just drill it out” method you sometimes hear about when a coin box key goes missing. If you’ve ever tried this yourself with a regular drill bit and had no luck, you’re not alone. Coin box locks—especially those from manufacturers like Greenwald and ESD—are specifically designed to resist tampering, and that includes drilling.

Why the struggle? Most coin box locks are made from hardened steel or contain anti-drill pins. This isn’t just a marketing gimmick; it’s an intentional security feature. Your standard hardware store drill bits (even the ones you might use for basic metal) often aren’t up to the task—they’ll dull quickly, skate right off the cylinder, or worse, break inside the lock.

To make matters trickier:

• Many locks use complex pin arrangements or shields that deflect the bit.
• The small, rounded face of tubular locks offers almost no surface area to grab.
• Heat from aggressive drilling will just harden the metal further, making it even more stubborn.

We use special carbide or cobalt-tipped bits—and a healthy amount of patience—any time we have no other choice. But honestly, it’s the option of last resort. Whenever possible, having that key code or working with the original manufacturer is far less stressful (and doesn’t risk damaging your machine).

Replacing Greenwald or ESD Coin Box Keys

Now, let’s say you realize you need a new key for a Greenwald or ESD coin box—what’s next? Since these keys are uniquely coded for security, replacements can only come directly from the original manufacturer or one of their authorized distributors.

If you’ve recorded that all-important serial number (like we recommend!), you’re already ahead. Here’s what to do:

• Contact the right manufacturer:
  • For Greenwald coin boxes, reach out to Greenwald Industries at 800-221-0982 or fax them at 860-526-4250.
  • For ESD coin boxes, call ESD Inc. at 800-523-1510 or fax 215-643-4623.

Provide the serial code when you get in touch, and they’ll guide you through obtaining a replacement.

Remember, for security reasons, we can’t supply keys for these brands, nor can their competitors—this process protects you and your property.

By following these steps and staying organized with your key codes, you’ll avoid unnecessary headaches and keep your laundry system running smoothly.

Where to Get Replacement Keys and Locks for Changers

If you find yourself needing keys or replacement locks for your laundry changer, don’t worry—there’s a reliable solution. We recommend reaching out to specialized suppliers like Midwest Security Products in Toledo, Ohio. They offer a wide selection of keys and lock replacements perfect for most coin-operated laundry equipment.

Just give them a call at 800-767-6894, and they’ll help you track down the specific key or lock you need for your coin changer. Having this resource on hand can save you a lot of headaches and ensure your laundry operations keep running smoothly.

Can You Get Replacement Keys for Other Brands?

Keep in mind, though, replacement keys aren’t universal across manufacturers. If your coin box uses a lock made by someone like Greenwald or ESD, only that manufacturer (or their authorized distributors) can provide a matching key. For security reasons, companies don’t exchange keys or codes with each other—so you’ll need to reach out to the original lock maker for those specific replacements.

This safeguard makes sure only the right people can access your laundry revenue, which is a win for both you and your tenants.

How Long Does It Take to Get Replacement Keys?

Now, a quick word about timing—replacement keys aren’t always ready overnight. If the coin box key you need matches a standard serial number from major U.S. Lock suppliers, you can usually expect a quick turnaround (often shipping out within a few business days).

However, certain codes, especially for locks manufactured overseas or rare imports, can take much longer to track down. In some cases, we’ve seen wait times stretch out for several weeks, and on rare occasions, even a couple of months if the lock is particularly obscure.

That’s why we always take serial numbers the moment we arrive—so you’re not caught off guard or left with frustrated tenants and a jammed laundry schedule. Planning ahead is key (no pun intended) to keeping your laundry operations running smoothly.

What If the Keys Are No Longer Available?

It’s worth noting that in some cases, the original keys just can’t be replaced. This often happens with older machines—sometimes made by brands like ABT or National—especially if they use out-of-date lock types, like certain tubular locks with wider diameters.

When you’re dealing with these older or obsolete locks, it may not be possible to get a new key, no matter how many locksmiths you call or codes you have recorded. In those situations, your best bet is to plan on replacing the coin box or upgrading the lock itself. This ensures everything is secure and accessible going forward, without resorting to damaging the equipment.

How to Install a New Coin Box After Removal

Ready to give your machine a fresh start? Installing a new coin box is a straightforward process—no need for a degree in engineering or a magician’s touch.

Here’s how to get your new coin box securely in place:

1. Make sure the power is off
   Safety first! Always unplug the machine before working around the cash box compartment.
2. Line up the coin box
   Slide the new coin box into the compartment, ensuring it sits flush and is properly aligned with the lock opening.
3. Install and secure the lock
   Insert the new lock cylinder (selecting a high-security model from brands like Medeco or Abloy is always a good idea for peace of mind). Tighten it according to the manufacturer’s instructions—no need to channel your inner bodybuilder; snug and secure is perfect.
4. Test for fit and function
   Gently open and close the coin box using the new key, ensuring smooth movement and proper locking. If anything feels sticky, double-check alignment before powering up.

And that’s it—your laundry machine is ready to earn its keep once more, with security just as tight as the day it rolled off the assembly line.

What If the Dryer Stops Because the Coin Box Is Full?

Let’s face it—sometimes the most reliable piece of your laundry setup throws a curveball, and a coin box stuffed to the brim can bring everything to a halt. If your dryer stopped working because the coin box is maxed out and you can’t get inside, don’t worry, there’s a logical path forward.

Start by confirming the machine is powered down for safety. Then, check if you have the right key or access to remove and empty the coin box. No luck? This is where a little advance planning or teamwork comes in handy; reach out to anyone else who might have a spare key or keep a record of the lock code.

But if the key is truly nowhere to be found:

• Double-down on documentation: Jot down the lock brand and serial number if possible.
• Contact the lock manufacturer or your distributor: Greenwald, ESD, or other major brands can often provide guidance or help you order a replacement key—just be prepared for proof of ownership.

And when neither a key nor a replacement is feasible (maybe with an ancient, obscure lock), you may need to look at removing and replacing the coin box altogether. This might feel like an inconvenience, but it’s the safest way to protect your equipment and revenue—no need to risk prying or damaging the cabinet. Once you have access again, emptying that overflowing coin box will get your dryer humming along in no time.

If you ever find yourself facing a locked-out coin box with a growing backlog of quarters, a little preparation goes a long way—and your tenants will thank you for keeping laundry day on schedule!

What’s the Best Way to Drill Out a Stuck or Locked Coin Box?

If you’ve exhausted all other options and still can’t access a stubborn coin box—whether it’s because the key is lost, broken, or the lock simply refuses to budge—drilling out the lock can be an efficient solution. Just be sure to take proper safety precautions, and only proceed if you’re the authorized owner or manager of the equipment.

Here’s a simple, straightforward method:

1. Start with a Center Punch:
   Use a bull nose center punch to create a mark directly in the middle of the keyhole. This gives your drill bit a place to start and helps prevent it from wandering as you begin to drill.
2. Drill Into the Center of the Lock:
   Grab a 1/2-inch drill bit (or similar, depending on your specific lock size) and carefully drill straight into the center of the lock cylinder. Take your time, applying steady pressure. Most standard coin box locks can be drilled out in just a couple of minutes.
3. Remove Residual Pieces and Open the Box:
   Once you’ve drilled through, the lock should release. You can now open the coin box and replace the lock or the box itself as needed.

This approach is often quicker than you might expect—sometimes taking under a minute with the right tools. Just remember, after drilling out any lock, you’ll need to install a brand-new high-security replacement to keep your laundry revenue safe and your tenants reassured.

How to Remove a Stuck Coin Box Lock Without Damaging the Machine

Let’s say you find yourself needing to drill out a stubborn coin box lock—maybe the key is long gone, or the lock simply won’t budge. It’s possible to tackle this without leaving battle scars on your washer or dryer. Here’s how to get the job done safely:

• Unplug first: Always unplug your machine before starting any work—safety first!
• Mark your drilling spot: Use a center punch or similar tool to gently mark the very center of the lock cylinder. This step helps your drill bit stay in place, so you don’t end up scratching up the coin box or the surface around it.
• Go slow and steady: Start drilling with a small (pilot) drill bit, and gradually increase to a larger size. Resist the urge to rush or apply extra pressure—let the drill do the work. This prevents the bit from slipping and reduces the chance of damaging any neighboring parts.
• Use the right tools: Choose a drill bit suited for metal, and position your hands securely so nothing slips as you work.
• Keep it clean: Work in a clear, well-lit space, and lay down a towel or drop cloth to catch any stray shavings. This makes clean-up easier and keeps metal debris from finding its way into hard-to-reach places.

By taking these precautions, you’ll keep the surrounding panels and electronics safe—plus, you’ll avoid turning a tough lock into a bigger repair bill. If you’re not comfortable with power tools or if the lock proves especially tricky, don’t hesitate to call in a locksmith who specializes in high-security locks like Medeco or Abloy.

Removing a coin box lock can sound daunting, but with patience and care, you’ll keep both your equipment and your sanity intact.

What If Drilling Doesn’t Work? Alternative Solutions for Tough Coin Box Locks

Sometimes, even after you’ve followed all the usual steps—center punching, careful drilling, and escalating to larger bits—the lock simply refuses to give up its secrets. So, what do you do if the lockout blues are turning into a full-on coin box nightmare?

Here are a few alternative routes to consider if your standard lock-removal tactics just aren’t cutting it:

• Upgrade Your Tool Arsenal:
  If a standard drill bit won’t make a dent, try switching to a carbide-tipped bit or even a hole saw specifically designed for hardened steel. Some commercial coin vaults, especially those sporting high-security mechanisms, are built to withstand basic attacks—hence the need for a little extra firepower.
• Target the Lock Body (If Safe):
  On rare occasions, the lock may feature anti-drill guards or rods that extend deep into the box, making front-facing attacks nearly useless. In these cases, carefully drilling through the face of the coin vault itself—even if it means sacrificing the box—can let you access the interior locking rod. Save this for last resort situations, and only if replacement parts are readily available.
• Specialty Extractors:
  Some broken or jammed locks respond well to screw extractors—the same kind you’d use to remove a snapped bolt. Insert the extractor into your drilled pilot hole, turn counterclockwise, and see if you can coax the lock core out with some gentle persuasion.
• Outsource to a Locksmith (With the Right Tools):
  If you’re staring down a Medeco, Abloy, or other high-security lock and the above options don’t budge it, it might be time to bring in a locksmith specializing in commercial or high-security locks. Pros like these typically carry diamond hole saws and specialty tools that won’t risk collateral damage to your machine.
• Consult the Manufacturer:
  In situations where the coin vault features internal rods, multiple lock faces, or other unique security features (here’s looking at you, industrial Whirlpool and Huebsch models), reach out directly to the manufacturer or an authorized service provider. They may have removal guides, service tools, or even replacement coin boxes to help minimize downtime.

Quick Tip: Before resorting to more aggressive tactics, double-check the model manual or available service diagrams—sometimes, a hidden latch or release catch is all that’s standing between you and success.

If all else fails, remember that a heavily damaged coin box is replaceable; your washers and dryers, on the other hand, are worth a little extra patience and care. Don’t be shy about calling in expert help when things get hairy—a locksmith visit is cheaper than a new machine!

How to Safely Remove and Replace a Coin Box Lock

If your coin box lock has jammed or the original keys are long gone, you might find yourself needing to remove and replace it altogether. Here’s a safe, step-by-step approach to tackle the job—without risking damage to your machines or your wallet:

1. Power Down First:
   Always unplug the washer or dryer before starting any work. Safety first—no exceptions.
2. Secure Your Work Area:
   Clear the space around the lock and ensure you have plenty of lighting. This helps prevent accidental scratches or slips while working.
3. Mark the Center:
   Use a center punch (or an awl) to gently mark the center of the lock cylinder. This step keeps your drill bit exactly where it belongs and helps prevent it from wandering across the face of the lock.
4. Drilling Out the Lock:
   • Start with a small drill bit to create a pilot hole.
   • Gradually work up to a larger bit, drilling slowly through the lock cylinder and pins.
   • Take your time—rushing risks damaging the coin box or surrounding parts.
   • Tip: Use a sharp bit and steady pressure rather than brute force.
5. Remove the Old Lock:
   Once the internal pins are drilled out, the lock cylinder should release. Carefully pull it free.
6. Install the New Lock:
   Select a replacement lock compatible with your machine—brands like Medeco and Abloy offer excellent, high-security options for laundry applications. Insert and secure the new lock, making sure it operates smoothly.
7. Routine Maintenance:
   Give the new lock a quick spray with a recommended lock lubricant. A little preventative care goes a long way in keeping future jams at bay.

By following these steps, you’ll safely replace a stubborn or obsolete coin box lock—helping to secure your collections and keep your laundry room running like a well-oiled machine.

Drilling Out a Stuck Coin Box Lock: Step-by-Step

If you’re faced with a coin box lock that refuses to budge—and replacement keys are simply out of reach—sometimes drilling out the lock becomes the only reliable option. While it sounds intimidating, with the right tools and a little know-how, you can safely remove a stubborn lock without destroying the surrounding coin box or washer.

Here’s how to tackle this common issue:

1. Gather the Right Tools
   • A bull nose (center) punch
   • A power drill
   • Drill bits, starting small and working up to about ½ inch in size
   • Safety glasses
   • Vacuum or magnet for cleaning up metal shavings
2. Prep the Area
   Unplug the machine to ensure your safety. Clear any laundry or clutter around the coin box so you have room to work. Make sure the area is well-lit—good visibility helps prevent accidental slips or scratches.
3. Start with Precision
   Use the center punch to make a small indentation right in the middle of the lock’s key slot. This prevents the drill bit from sliding off and keeps your aim true.
4. Work Your Way Up
   Begin by unplugging the machine to ensure your safety, then locate the coin box locking mechanism—most commonly a cam lock found on commercial laundry equipment. Make sure the area around the coin box is clear, giving yourself ample space to work.Begin drilling with a small bit to create a pilot hole, then gradually step up to larger bits—ending with a ½ inch bit for most commercial locks (including those by Greenwald, ESD, or Medeco). Go slow and steady; excessive force can damage the coin box itself.
   • If the lock cylinder is particularly stubborn, a flathead screwdriver or lock-picking tool may help—but only attempt gentle turning before drilling to avoid unnecessary damage.
   • If drilling, be patient. Rushing can crack the coin box or mar nearby panels.
5. Remove the Old Lock
   Once you’ve drilled through the center, the lock cylinder should break free. Carefully pull it out using pliers if needed. If the lock cover is in the way, you may need to gently pry it off, but always avoid forceful prying that could deform the box or panel.
6. Clean and Install
   Clear out any debris or metal shards using a vacuum or magnet, then install your new lock. If you’re often facing stuck locks, consider lubricating the new mechanism or upgrading to a higher-security option from trusted brands like Abloy or Medeco.

Pro Tip:
If you manage a property with multiple machines, keep spare keys handy and periodically request extras from the manufacturer to avoid future lockouts. A little preventative planning can save a lot of hassle.

With patience and the right technique, you can handle even the most stubborn locks—saving your equipment and sidestepping a laundromat headache.

When Drilling Isn’t Enough: Advanced Tactics for Tough Coin Box Locks

Occasionally, you’ll come across a coin box lock that scoffs at standard drilling techniques—especially on older or more complex models. So, what’s your next move when drilling out the cylinder just won’t set it free?

Here’s a battle-tested plan for those extra-stubborn situations:

• Double-Check Your Progress:
  If you’ve already drilled out the main lock cylinder and nothing’s budging, shine a flashlight into the opening. Look for hidden rods or internal mechanisms that could be holding the vault in place. Some vintage coin vaults include rods extending deep into the box or cabinet, making straight-on drilling less effective.
• Upgrade Your Tools:
  Standard drill bits might not cut it—literally. If progress stalls, switch to a carbide-tipped hole saw or a heavy-duty metal-cutting bit. These can chew through reinforced steel or thicker outer layers that normal bits just bounce off.
• Target Weak Points:
  Examine the construction of the coin box. Sometimes, drilling into the lock face isn’t enough—especially when there are additional locking bars or sleeves at the back. You may need to expand your approach by carefully drilling around the perimeter or through the side panels (when accessible).
• Controlled Destruction:
  When all else fails, you may need to sacrifice the old coin vault for the greater good of your sanity. Use a hole saw or angle grinder to cut directly into the most vulnerable part of the box itself. Yes, this will destroy the vault, but sometimes that’s the only way forward.
• Clean Up and Replace:
  Once you’ve managed to free the coin vault, be meticulous about cleaning up all metal shavings and debris to prevent future jams. At this stage, it’s usually best to replace both the damaged lock and the coin vault itself. Reach out to your equipment distributor for OEM parts, or upgrade to a higher-security brand like Medeco or Abloy for peace of mind.

A word to the wise: don’t be discouraged if your lock removal turns into a mini-epic. Tough locks are designed to protect your quarters, after all! And after some elbow grease (and possibly a few colorful words), your laundry room will be back in business—with a more secure, hassle-free setup for the future.

Should You Replace Locks and Coin Boxes on Older Machines?

If your machines have seen a few decades, it might actually make sense to swap out those original locks and coin boxes altogether. Not only does this give you a fresh start with a new set of keys and codes, but it also boosts security and can save you future headaches.

Brands like Medeco and Abloy offer high-security locks designed for laundry applications, so you can select a system that works better for your property’s needs. If you’re not sure about the best approach, don’t hesitate to reach out to a locksmith or your distributor for specific recommendations—they’ve seen it all. If you’ve lost your keys, contacting the lock manufacturer or a locksmith who specializes in coin machine locks is usually your best bet for obtaining replacements or even exploring master key options. This proactive step can help ensure your machines stay secure and accessible, without the hassle of drilling or damaging your equipment.

Staying proactive with new hardware can keep your collections running smoothly and give both you and your tenants some extra peace of mind.

Matching Keys Across Multiple Machines: What to Know

If you’re hoping to simplify your setup so that one key fits all your machines, here’s the deal: Typically, all machines need to be re-keyed by a locksmith to share the same key. This only works if the machines are the same brand and use compatible lock styles; different brands or box designs usually require different keys altogether. Unfortunately, there isn’t a universal “master key” that will fit across different brands or styles of coin boxes and service panels.

Take a close look at the numbers stamped on your current locks or keys (for example, you might see codes like 777 or 701). Different numbers indicate different lock codes, which means they’re not keyed alike. If you want all your service panels or coin boxes to use the same key, you’ll need to change out all the locks to ones that match—often by ordering a full set of new locks keyed alike from a reputable supplier.

Service Panel Locks vs. Coin Box Locks

It’s worth noting that service panel locks and coin box locks are usually separate: even if you match all the service panel locks to one key, the coin boxes themselves may still require a different key unless you replace every coin box with a matching model.

Staying proactive with new hardware can keep your collections running smoothly and give both you and your tenants some extra peace of mind.

Should You Use a Master Key System?

For properties with multiple machines, consider master keys for coin-operated washers and dryers. These handy systems allow access to several locks with a single key, streamlining maintenance and making collections a breeze. Start by identifying the lock brand and model on each machine to source compatible master keys. If a universal master key isn’t available for your mix of locks, rekeying them to a single system can be a smart upgrade.

But remember—keep all spare keys securely stored, and always document every key’s serial number and location. This habit is a lifesaver when keys inevitably go missing and you don’t want to spend hours turning over every drawer.

Can All Your Coin-Op Machines Be Rekeyed to Use a Single Key?

If you’re tired of carrying around jangling rings of mismatched keys, you’re not alone. The good news: many coin-operated machines can be rekeyed so a single key opens them all—provided they’re compatible. Here’s what you should know:

• Same Brand, Same Lock Style: If your machines are the same brand and use similar lock types, a locksmith can usually rekey them to match one key. This makes collections and maintenance far less of a juggling act.
• Different Brands or Mechanisms: If your machines come from different manufacturers or use various lock mechanisms, achieving a “one-key-fits-all” setup may be tricky. In some cases, you might need to swap out all the locks for a compatible line (for example, all Medeco or all Abloy locks) to standardize your key.
• Consult a Pro: Not sure what will work? A qualified locksmith or laundry distributor can review your current hardware and suggest the best solution—saving you time and ensuring your new keys are secure.

By rekeying or upgrading, you can simplify access, streamline operations, and avoid the infamous janitor’s key chain—always a win in any laundry room.

Do Companies Track Which Keys Belong to Which Laundry Machines?

It’s a great question, and one that trips up even some seasoned landlords. Most key manufacturers—especially big players like Medeco or Dexter—do not maintain a master list tying specific key orders to exact laundromats or buildings. That means if you lose your key, they can’t just look you up in some super-secret key registry and tell you, “Ah yes, the Green Ocean Property coin box model #12345, here’s your spare.”

Instead, key makers rely solely on the unique code or serial number stamped on the key or lock. When you need a replacement, you’ll be asked for this code—no code, no key. They don’t process orders based on vague requests like, “Can you send another one just like the key I bought ten years ago?” The system is intentional—protecting property owners and discouraging unauthorized duplication.

So, as part of our routine, we always make sure to document those serial numbers right away. That way, if the key ever goes missing, we’re not left scrambling—or worse, having to replace the entire coin box.

If you do lose a key and don’t have the code, your best bet is to contact the lock’s manufacturer or a locksmith who specializes in coin machine locks. They can sometimes offer replacement or master key solutions if you can provide enough identifying details about your lock or machine.

Maintenance Tips to Keep Coin Box Locks from Jamming

Now, if you want to avoid finding yourself with a jammed lock and a line of irritated tenants, a little routine maintenance goes a long way. Here are some simple steps you can take:

• Lubricate regularly: Applying a light, non-greasy lubricant like graphite or Tri-Flow to the lock mechanism can help prevent sticking—just be sure to avoid heavy oils that attract lint and dust.
• Keep coin boxes clean: Dirt, detergent residue, and stray coins can all contribute to jams. Wipe down the interior and the keyway every so often, and give a quick blast with compressed air if you notice buildup.
• Inspect for wear: Take a peek at your locks and keys periodically for signs of rust, bent keys, or other damage. Early detection means easier fixes.
• Replace worn parts promptly: If you spot a lock that’s starting to act up, don’t wait for a full-blown meltdown. Swapping out an old lock or key can spare a lot of hassle.

A bit of preventive care will save you from midnight lockouts and keep your laundry room humming along without interruption.

Essential Security Products for Coin Laundry Equipment

When it comes to safeguarding your coin-operated laundry equipment, there’s a full toolkit of products specifically designed to keep both your machines and your collections secure.

Here are some solutions you might consider:

• Heavy-duty coin boxes and money boxes: These are built to resist tampering and provide reliable protection for your coin collections.
• High-security locks and lock extensions: From Medeco to Abloy and other reputable brands, these secure your coin boxes and discourage any unauthorized attempts.
• Coin chutes and coin slides: Not only do these control access, but they’re also made to last, standing up to constant use and wear.
• Replacement keys and serial-matched key sets: Whether you lost those keys or just want backups, replacements matched to your coin box serial numbers can keep you prepared.
  If you’re facing a locked coin box and need quick access, there are also practical methods to consider. Using a bull nose center punch, for example, you can punch directly through the keyhole slot to breach the key guard from the center. Follow this by drilling into the center of the lock with a 1/2 inch drill bit. This straightforward approach can get the job done in just a few minutes—sometimes in under a minute—making it an efficient option when you’re in a pinch.
• Locking key rings and organizing accessories: Reduce the risk of misplaced keys and streamline management with key security products. If you’re managing washers and dryers from different brands, juggling a handful of unique keys can quickly become a headache. While a universal master key for all brands doesn’t exist, you can simplify your routine by consolidating locks where possible. For example, many service panel locks—especially those using round keys—can be re-keyed or replaced so they all use the same style and key number (such as “777”). Doing this means you could access multiple service panels with a single key, cutting down on the clutter.Keep in mind, though, that coin box locks are typically brand- and style-specific. Achieving a single key solution for coin boxes would require replacing all units with matching boxes and locks. For most owners, focusing on unifying service panel keys offers the biggest improvement in day-to-day efficiency.

  By pairing key ring organizers with a thoughtful lock strategy, you’ll spend less time searching and more time getting things done.

• Tokens, meters, and timers: For those who want a cashless operation, token kits and electronic meters offer an alternative level of control.
• Service door locks and accessories: Add another layer of protection to other vulnerable areas of your laundry machines.

As you can see, there’s a full lineup of components you can use to prevent headaches—so you stay ahead of the game and avoid emergencies like lost keys or forced entries.

We also know how to drill them with special bits, but that’s something we want to avoid.

But these are the small things that, as a property management company, we have the experience to go through and avoid unnecessary expenses for you, the landlord.

It’s just about being proactive and detail-oriented to get the information that you need.

How to Prevent Coin Box Locks from Jamming

One of the easiest ways to dodge future headaches with stuck or jammed coin box locks is to give them a little regular TLC. We recommend making it part of your maintenance checklist to periodically lubricate those locks—especially if your machines see a lot of use or are in humid environments (Boston basements, we’re looking at you).

A quick spritz with a graphite lubricant or a lock-specific spray every few months can keep everything moving smoothly. Avoid using heavy oils—those can actually attract grit and gum things up over time.

Pairing this with occasional cleaning (just a gentle blast of compressed air to clear out any dust or lint) will help your locks last longer and save you the hassle of wrestling with a stuck key during collections.

Taking a few preventative steps now means fewer emergencies and less chance of finding yourself stuck on laundry day—both for you and your tenants.

Should You Drill Out the Keyhole or the Rivets?

When you’re faced with a stubborn coin box lock and no key in sight, the question often comes up: is it simpler to drill out the keyhole or the rivets? After years of dealing with laundry rooms and tricky lockouts, here’s what I’ve found works best.

Drilling the keyhole typically proves the quickest and least destructive way to open a coin box. With a bull-nose center punch to start your hole, followed by a ½-inch drill bit, you can breach the lock’s core directly through the key slot. Most standard locks, including those from Medeco or similar reputable brands, give way in under a minute with the right tools. It’s surprisingly efficient, and it saves the surrounding hardware—which means you’re less likely to damage the coin box or door itself.

On the other hand, going after the rivets can be more tedious. Rivets are designed to be tamper-resistant, and drilling them out often involves awkward angles and leaves you with extra repair work. You may end up needing to replace more than just the lock, which, as any seasoned landlord can attest, adds time, cost, and hassle.

Our advice? Stick to drilling the keyhole if you have to resort to force. But ideally, keep track of those serial numbers and spare keys to avoid going down this path altogether. Prevention is always cheaper than repair—trust us, we’ve learned that one the hard way.

What If Standard Drill Bits Aren’t Doing the Trick?

Sometimes, the tried-and-true drill bit just won’t get the job done—especially with higher-security coin box locks from sturdy brands like Medeco or Abloy. If you find yourself staring down a lock that seems to laugh off your usual bits, don’t panic. There’s a next-level approach:

• Grab a bull nose center punch (often found at hardware stores). This nifty tool lets you create a solid starting point, right in the dead center of the keyhole. It’ll help prevent your drill from wandering, especially if you’re dealing with those slick, tamper-proof key guards.
• After marking your spot, switch to a heavy-duty (preferably cobalt or carbide-tipped) 1/2-inch drill bit. Drill directly into the center you just punched. These bits are designed to tackle hardened steel—perfect for the locks that just won’t budge.
• Keep steady pressure and patience. In most cases, this method can get that lock off in minutes, minimizing downtime for you and your tenants.

But what if even your best drill bits are barely making a dent, or the lock just keeps turning without budging? In rare cases—especially with reinforced coin vaults from brands like Medeco or Abloy—you may find the lock is so robust that conventional drilling simply isn’t enough. That’s when you might need to take it a step further:

• Consider using a carbide-tipped hole saw or similar heavy-duty tool to cut through the lock face or even the front of the coin vault itself. Some vaults are designed to resist just about everything short of full-on destruction, so be prepared for a little more effort (and possibly some collateral damage to the coin box).
• If you have to go this route, know that you’ll likely need to replace the entire vault once it’s removed. It’s not anyone’s favorite solution, but sometimes there’s no way around it.

As always, take necessary safety precautions and consult a professional locksmith if you’re unsure or want to avoid any risk of damaging your machine. The aim is to protect your investment, not turn laundry day into a demolition derby!

Preventing Drill Bit Slippage When Drilling Out a Coin Box Lock

If you ever find yourself needing to drill out a stubborn coin box lock, there’s a classic trick to save yourself some frustration: use a center punch to create a small dimple right at the center of the lock cylinder. This tiny indentation will guide your drill bit, helping prevent it from wandering off course as you start drilling. It’s one of those “measure twice, drill once” tips that keeps your work neat—especially helpful with the hardened locks from brands like Medeco or Abloy.

By taking this extra step, you not only make the process smoother but also protect the surrounding hardware from unnecessary scratches or damage. All in all, it’s another example of how a little attention to detail can save you both time and potential repair costs.
