How to reset combination for sentry safe?

This answer was rated:

I want to reset the comb for my Sentry safe but do not have the factory codes.

If this is a three-digit combo dial you cannot change it. The user code can be changed only.

If this is an electronic keypad the code is 1-7-5-0-0, then reset it to a new user code. If you have ever programmed a new user code, this number does not

work. Only for first time, then new user code changes the number. If you never changed to a new user code, this number will open the safe: 1-7-5-0-0

JACUSTOMER-qyjduax4- : This is not working (17500). What do I do because the safe is open, and bars have locked. my old code does not work anymore.

Craig : Is the 'amber' light on?

JACUSTOMER-qyjduax4- : Yes

Craig : Have you replaced the batteries yet? This is low batteries that need to be changed.

JACUSTOMER-qyjduax4- : Yes, the light goes on when I try to enter a code.

Craig : It's the batteries, you must replace them. That's what is happening, the batteries are low and will not operate.

JACUSTOMER-qyjduax4- : Ok that worked. Now my code to enter works again. How do i clear all codes and create a new one? My ex-wife had her own code, which i don't know and I had my own code as well.

Actually, I do know her code and would like to delete it. How would I do that?

Craig : There are 3 possible ways to unlock and access the safe:

1. Factory code: (Found on the first page of this guide) You can

always open the safe by entering the pre-set 5-digit factory code. This code cannot be deleted.

2. User code: If you prefer to employ your own code, you can program the safe to open using a 5-digit user code of your choice.

3. User pin: If you wish to give someone else temporary access to the safe, you can program a 5-digit user pin that can later be erased.

Programming the user code:

NOTE - One (1) user code is allowed.

To add:

1. Press the Prog key, then enter the 5-digit factory code.

2. Enter the 5-digit user code of your choice:

To delete:

1. Press the Prog key.

2. Enter the 5-digit factory code twice.

Programming user pin: NOTE - One (1) user pin is allowed.

To add:

1. Press the Prog key 2 times.

2. Enter your 5-digit user code.

3. Enter the 5-digit user pin of your choice.

To delete:

1. Press the Prog key 2 times.

2. Enter your 5-digit user code.

3. Enter 0, 0, 0, 0, 0.

NOTE: If your safe does not appear to be working, please check batteries before calling.
