I have sentry safe that i bought with keys need reset combo

I have a sentry safe 1250 .83 cubic and I have the key I was using the safe for awhile without the combination and just the key but now the key wont work and someone messed with the combination part which I dont know the combination i dont know what to do and I dont wanna trash this 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 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

Hey.

What model safe is it?
I have found a link to the Sentry safe website, where you can download product manuals for the safes. It is likely that you'll find information on code resetting there.

If you can provide anymore information in the mean time, I can also take a closer look to see if I can find the information out for you.

Thanks Sentry Safe Product Manuals

There is no default combination. Open it with the key and reset it to your own combination.

Try changing the batteries first. No the electronic combo would not be erased unless someone previously changed the combination. There is probably something causing the bolts to not retract. The lock may fail if there is any pressure on the bolts and or the door of the safe. Hopefully this information helps.

To order replacement keys, for small chests and files, you will need to know the key numbers which can be found right around where the key goes in. It should be a stamped number, letters, or both located around the keyhole. For Personal, Home and Home/Office Safes, you will need the model number and serial number. I think that the most economical place to buy keys is from www.SentrySafeShop.com. You can do a search for "lost keys" and it will give you a screen where you can enter your model number and key number. (It is a very easy screen to use. They just need 1.)Model # and 2.)Serial or Key #.)

In Summary:
For Small Chests or Files: A lock reference number is required. It will be a letter, a number, a letter and number, or "blank" (no letter or number), engraved/located on the silver cylinder of the lock. These are model numbers 0500, 1100, 1170, etc...

Combinations can also be ordered from the same website.

For Personal, Home and Home/Office Safes: (model numbers will begin with: S0, S3, S4, S5; I0, I3, I4, I5; A3, A4, A5; J3, J4, J5; L0, L3, ,CS,CSW,DA,DS,KS,KSW,MS,MSW,OA,OS,and SC): Indicate your model number and the safe serial number found on the front right-hand side of the door, between the hinges.

Hi.

The only way to open a sentry safe is by using a registered combo, or by contacting Sentry. There is no other simple and non destructive way to open a Sentry.

See here: Sentry respects strong security standards. There is no simple way of hacking a safe if you loos.

Press: Program 2x, enter a digit user-code (green led remains on), enter the 5 digit user pin (of your choice except 00000). After 5 digits entered, the green LED turns off.

You need to contact Sentry, they will send you an emergency unlock code.

Number in US is 1-800-828-1438.
