Master Lock combination locks are secure and durable locks which can have thousands (or tens of thousands, depending on the number of digits) of combinations.
It would take a very long time for someone to guess the combination that you set.
If the combination you choose gets discovered, however, you may want to reset the lock. The good news is that is very easy to do.
How to Reset a Customisable Combination Lock
Most Master Lock combination locks are factory set to open at either 0-0-0-0 or – – – -.
Open the lock using that setting, or if you have reset the lock to your own chosen combination, using that combination.
Turn the shackle on the lock one-quarter turn, so that the shackle’s notch aligns with the notch shown on the body of the lock.
Press and hold the shackle.
While holding the shackle in place, set the dials to your desired combination, so that the middle of each digit lines up with the stripe on the lock.
Release the shackle and return it to the closed position.
The lock is now set to your new combination, make sure you can remember it, and then scramble the digits to ‘lock’ your Master Lock.
What if You Have Forgotten the Combination?
If you have forgotten the combination for a standard, non-customisable Master Lock, then you can contact the manufacturer and they will tell you the combination.
To do this, you will need to prove that you own the lock. In addition, you must demonstrate that the lock is not attached to anything.
Master Lock will not provide combination information for a lock which is currently in use.
If the lock is a customisable lock, and you have forgotten the current combination, then Master Lock will not be able to help you.
You cannot reset the lock without knowing the current combination.
If you have a three-digit lock you could sit there and manually try each combination one digit at a time until you find the one that you need.
This will take a while even with 1000 combinations, but for a four digit lock that would be highly impractical.
Master Locks are very well made, and will not ‘crack’ open the way that some cheaper combination locks will.
This means that if you cannot find the combination through testing at home your best bet is to call in a locksmith.
Depending on the type of lock, a locksmith may be able to open the lock in a non-destructive way so that you can reset it, or force the lock open so that you can access whatever it was holding or protecting.
If you are trying to get your bike lock opened, or a lock that is securing a case, then you would be expected to be able to demonstrate ownership of the secured object.
We recommend that you choose the combination for your lock carefully and that you do not leave your lock ‘unlocked’ when it is not in use.
Otherwise, it is easy for someone to mistakenly reset the combination if they play around with the lock.
Close and scramble the lock to prevent such accidents from happening.
