Open the safe by typing the three-, four- or five-digit factory code or the user code you set into the keypad. If you cannot remember the code, call the Sentry Safe customer service number at 800-828-1438. If you registered your safe and have a username and password, you can retrieve the combination on the Sentry Safe website. If you have not registered, follow the instructions on the website to obtain a notarized form to confirm you own the safe and need a new combination.
Hold down the “PROG” key (program key) and, at the same time, enter the factory code two times in a row. This will delete your user code.
Press and release the “PROG” key, then immediately enter the factory code one time.
Enter a new three-, four- or five-digit code. You must choose the same number of digits as your former code. For example, if your former code was four digits, you must chose a four-digit code.
Write down your new user code and put it in a safe location.
