The process of changing a combination lock is different based on what type of combination lock you are working with, as well as what type of device the combination lock is affixed to. Here’s a guide to opening up combination locks, as prepared by the commercial locksmith experts at SOS Locksmith. Of course, these many techniques vary on the exact make and model of safe that you’re dealing with – however, this guide applies to a broad range of different types of safes.
General Manual Dial Safe Changing Procedure
-
Open up the safe
-
With the door open, move the dial according to the existing number combination, but move the numbers to the change mark (to the left of the 12 o clock mark.)
-
Leave the dial on the last number of the combination.
-
Put the change key into the keyhole on the inside of the safe door.
-
Turn the key, but don’t torque it into the keyway.
-
Dial in the new combination by using the change mark, and according to the same rotating pattern that you normally use to open up the safe.
-
Leave the safe dial on the last number of the new number combination.
-
Turn, and take out the change key.
-
Try this combination a few times while the safe door is open.
General Digital Safe Changing Procedure

The lock will then change to programming mode. Press the current safe code, then ‘#’.
-
Wait until you hear a series of unique beeping noises.
