Breaking into a Master Lock can be done through several bypass techniques, ranging from simple physical strikes to manual "decoding" of combinations.
You can visit a Master Lock Distributor / Retailer or submit a Lost Combination form. Bring your lock to the retailer. Be sure that it is not attached to anything. If you do not bring the lock, or it is attached to something, we will not release the combination.
Known weak points: Thieves target Master Locks because they know exactly how to break them. No advanced pin features: Most models lack security pins like spools or serrated pins, making them easier to pick. Fails under pressure: A quick strike, pry, or twist is often enough to force the shackle open without finesse.
What should I do? If you recorded the key number, you may be able to get replacement keys from a hardware store or locksmith. If you didn't record the number, contact a locksmith to remove your lock. Please note there will likely be a fee for this service.
To force a lock open, choose a method based on the lock type: credit card (for standard spring-latch doors), lock picking (for pin-tumbler locks), or cutting/shimming (for padlocks). Always ensure you have the legal right to access the lock before proceeding.
Using a Knife
Start by carefully inserting the knife into the lock, manuvering until it touches the back of the lock. Continue to be as gentle as possible so as not to damage any piece of the lock. This is the part where you try turning the knife like you would a key. Only turn slightly, then jiggle the knife.
The default factory code for most Master Lock combination locks and lock boxes is 0-0-0 (for 3-digit locks) or 0-0-0-0 (for 4-digit locks).
No, all Master Lock keys are not the same. Each lock is made with a unique combination of pins, meaning a key cut for one lock will generally not open another. However, because they are mass-produced, identical key cuts are used repeatedly, so another person may have the exact same key as you.
Home Depot can duplicate keys as long as you have the original. They can also duplicate car keys and transponder keys but they can't give you access to your car if you have lost your car key. They can't rekey a lock or install high-security locks around your home or business.
Yes, most standard Master Lock padlocks can be picked easily using a basic tension tool and a hook or rake pick, often crafted from simple DIY tools like paper clips or bobby pins.
Generally, all you'll need to pick a lock are some picks (long, thin metal pieces with curved ends of different shapes for different types of locks) and a tension wrench. You can use paperclips as picks in a pinch, and a tension wrench can be any tool used to create tension, including a flathead screwdriver.
The Master Lock was first officially broken on the March 19 episode of Raw, by ECW World Champion Bobby Lashley.
Resetting a 4-number Master Lock involves opening the lock, turning the shackle 90 or 180 degrees, pressing it down, and setting your new numbers while holding the shackle.
Opening a 3-digit combination lock depends on whether it is a traditional rotary dial (like a Master Lock) or a multi-dial luggage/padlock. For rotary locks, use the classic right-left-right sequence. For dial locks, pull the shackle and rotate until it clicks to bypass the code.
Yes, standard bolt cutters can easily cut through most standard, inexpensive Master Locks. However, their effectiveness depends heavily on the size of the cutters and the specific model of the padlock.
Bump keys are specially cut keys that can bypass the security mechanisms built into traditional pin and tumbler locks. Bump keys are also referred to as “999 keys” because all of their ridges are cut to the maximum depth (999) in a key-making machine.
Yes, Home Depot can cut and duplicate standard Master Lock keys. You can bring your existing key to the hardware counter where an associate can cut a matching replacement from standard blanks (such as the popular HY-KO Blank Master Lock Key).
To open a standard Master Lock when you've forgotten the combination, you can "crack" the code using the shackle's tension or retrieve the code directly from Master Lock.
Enter the combination and pull the shackle to open. If this is a factory-new lock, the combination is 0-0-0-0. Turn Shackle 90° to position 1. Push shackle in to lock until it clicks.
Yes, a locksmith can easily open a Master Lock. Whether it is a keyed padlock or a combination dial, professionals use specialized tools to pick or bypass the lock without causing damage. If the lock is a heavy-duty model or jammed, they can also use bolt cutters or grinders to remove it.
Yes, a magnet can open certain types of locks, but it depends entirely on the lock's design and mechanism. While a magnet won't work on high-security padlocks or deadbolts, it can successfully manipulate some standard, smart, and magnetically keyed locks.
Common household items for lock picking include paperclips, bobby pins, and safety pins, which can be shaped into a tension wrench and pick. Aluminum can strips or small flathead screwdrivers may also work.
