Are Master Lock Products Easy to Open Without a Key?
While Master Lock has the most recognizable name in the padlock industry, they don’t have the most secure products. As more evidence comes out about the weak designs of Master Lock, it has become obvious they don’t bring confidence to customers.
From critical design flaws to weak construction, you can find numerous ways to exploit a standard Master Lock product. If you need to open one of these locks without a key, you won’t have a shortage of options.
Most Master Lock products have the same lock core that can be bypassed with basic lockpicking knowledge. With this information in mind, let’s move on to the methods to open a Master Lock without a key.
5 Ways to Open a Master Lock Without a Key
Using Two Wrenches
Using wrenches to open a padlock has become a popular option. This strategy doesn’t require technical skills like lockpicking and can be completed quickly. We included this technique first as it is the easiest option and uses basic hand tools.
The Master Lock padlock will open as the two wrenches exert a ton of force on the shackle. In the past, the technique involved placing the wrenches side-by-side and pushing the handles together to break the lock.
However, the updated technique makes the two wrenches much easier to use. Follow these steps to open a Master Lock with two wrenches:
- Take a pair of large crescent wrenches (22-24mm) and place one wrench in the lock shackle.
- Take the other wrench and turn it so it faces vertically. Place the wrench on top of the first wrench and prepare to pry the lock open.
- When prying the lock open, you should hold the wrench on the bottom while you push the handle of the other wrench to open it.
In most cases, you will break the end of the lock shackle and make it unusable in the future. However, the force required to break the Master Lock padlock will be easier than other lock manufacturers.
Hitting Lock With Hammer
While this may be unfortunate news, a Master Lock can be opened with one hammer hit in the right spot. In a critical design flaw, the padlocks have a weak locking mechanism that unlocks the shackle when impacted.
When the padlock is closed, there are spring locking components that keep the shackle within the lock body. However, when you hit the lock body with a hammer or other hard object, it will release from the padlock.
The most common Master Lock product model that is victim to this strategy is the Master Lock #3. This laminated steel lock can be opened with one hit in the right location, and open the Master Lock without a key.
Picking the Lock
If you want to use the Master Lock padlock after opening it, your best option is to pick the lock. A lockpicking professional can open the lock and remain careful to ensure it’s not damaged in the process.
When beginners first learn how to pick a lock, they typically start with Master Lock products as they have the simplest designs. If you want to get your start in the lockpicking hobby, learning how to open a Master Lock without a key may be your first!
However, if you want to skip the learning process, you can work with a local locksmith to open the Master Lock. A locksmith will charge $50-$75 per hour when called to a home to pick a padlock.
Cut It With Bolt Cutters
One of the best ways to cut a lock is with a pair of bolt cutters. This method is used for numerous padlocks, not just those manufactured by Master Lock. The lock’s shackle is similar to a bolt, so the bolt cutters will easily cut through it.
When using a bolt cutter, we recommend choosing a 14” or longer option for the process. The bigger bolt cutters have more leverage and will avoid putting too much stress on your body.
The only time this option will not work is if you have a Master Lock with a disc padlock design. Round locks can’t be cut, as you can’t gain access to the shackle with a large tool like bolt cutters.
Cut Shackle With Angle Grinder
If your Master Lock has a round design, your best option is an angle grinder. The angle grinder will cut through the shackle of the padlock. Along with cutting a round lock, this option is good for any type of padlock.
For readers that don’t own an angle grinder, you can rent them from your local hardware store. If you use an angle grinder, you should wear the proper safety gear, like eye protection and gloves.
The angle grinder will produce sparks when you cut through metal materials other than aluminum. If used correctly, the Master Lock’s shackle should be cut within a few seconds, allowing you to access your belongings.
Frequently Asked Questions
The default combination for a Master Lock depends on the specific model. However, in most cases, Master Locks are not sold with a preset default combination. Instead, they come with a unique combination in the instruction manual set by the user when they first purchase the lock.
Wafer locks, as used in many Master Lock products, operate using flat metal wafers instead of pins. The bump keying technique is less effective on wafer locks than traditional pin-tumbler locks. While it may be possible to bump key a Master Lock with a wafer mechanism, it is generally less reliable than bumping a pin-tumbler padlock.
Some older or lower-quality Master Locks might have design flaws or manufacturing inconsistencies that make them vulnerable to certain picking techniques. However, Master Lock has made efforts to improve the security of their locks, and some of their higher-end models can be quite challenging to pick.
