  • Combination to lock

Maintain lock security; keep the combination safe.

Master combination locks offer an easy and efficient way to secure your personal belongings at school, in the gym or around the office. A standard combination Master lock comes with a three-number combination code inside the packaging. Memorize your code or keep the sticker in a safe place so you can refer to the code later if you forget it. Master combination padlocks also come in resettable versions, and you can set the combination for these locks yourself. Opening your combination Master lock is very easy, and will only take a few seconds.


Step 1

Combination padlocks protect your stuff.

Hold the lock with the black combination dial facing you. Make sure the numbers on the combination dial are displayed upright and are not upside down.

Step 2

Turn the combination dial three times to your right. On the third turn, stop on the first number of your combination code.


Step 3

Turn the combination dial to the left; go past the first number of your combination code one time before stopping on the second number of your code.

Step 4

Turn the combination dial to the right and stop on the third number of your combination code.

Step 5

Pull down on the lock; the top shackle should open. If it does not, make sure you are entering the right combination code and repeat Steps 1 through 4.


If you lose or forget the combination to your Master combination lock, visit the Masterlock website (see Resources) for details on contacting their warehouse. You will need to send several documents to the address that is listed, including a notarized copy of the Lost Combination Form--available on the website--and a photocopy of your lock's serial number. Masterlock takes 4 to 6 weeks to process lost combinations. Unfortunately, if your combination lock is attached to something, Masterlock will not send you the combination code. In this case, you will need to have a locksmith remove your lock.
