How Do You Reset the Combination on a Sentry Safe?
To reset the combination on a Sentry safe, open the door of the safe, delete the existing codes, press the PROG or P key and enter the factory code. Finally, enter a new five-digit number as per individual preference, which is the new user combination.
It is always prudent to reset the combination on a Sentry safe when the door is open because it prevents the user from being locked out. To open the Sentry safe door, type the five-digit factory code given in the owner's manual. This factory code cannot be altered.
To delete the existing codes on newer models of the safe, press the P button. Then, type the factory code and follow it up by inputting "00000" into the safe. On older models of the Sentry safe, press the PROG button and type the factory code two times.
After deleting the existing codes, press the PROG or P key and then enter the factory code once again. Within five seconds, type a new five-digit number, which is the new user code. To verify if the user code is working, retype it and then close the door of the safe. The user code is the primary code for opening the safe, and users can reset it as often as they desire.
