If Hello melody plays after replacing batteries, 00 00 00 is the default code.

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 as of 2015, 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 want too

i think with this kind of safe it comes with 2 keys, one which requires the code to be entered, and a master key that will unlock without requiring the code.

if you have the master key, just use that.

after you have opened the door you can reset the code by pressing the reset button (a pin / paperclip required to press)
on the back of the door.

I cannot open my Noble safe. I havent used it for 1 year, it has no battery and cant open it with my key. I cant remember the code, but i wont be able ti use it with no batteries.

What can i do

Hi I have the key and know the code , I want to change the code on my Honeywell 2087D I have lost the book what's the trick? I have no red reset button. Please HELP!!!! Sharon

are you the manager user of the safe?if yes,you can reset a new code by yourself.

On this safe, first hold the reset button on the bottom for 30 seconds to reset it. The code should now be the factory default of 1234. Next, type 1-2-3-4 and ot your thumb to the fingerprint reader on the front to open it. It should open. If it starts saying activated, just enter the code once more.

Now to reset the code. With the safe open, enter the new code and press star. Do this once more to confirm. You should hear an acknowledgment tone that it is now set.
