Why won't safe open ? I have 3 keys that fit safe, but door does not open. I do not know combination. I thought the key would open it, as I thought it was an override key

It also has a small hole that indicates DC connection? Has 3 lights that don't work. Its 5 years old, but has never been used, I don't think its ever been opened, and I don't recall ever seeing a combination. I assume combo inside?

SOURCE: unable to open electronic safe

Locksmiths say this is how to install sentry safe batteries
slide open the battery cover located just below the keypad.
Insert a paper clip or pen point into the small hole in the cover. Push in while sliding cover to the right. Disconnect and remove the battery holder. Insert the 4-batteries as indicated.
reconnect the connector and put back the battery holder. Slide the cover back in place.
How do I insert the batteries on my advanced electronic lock safe? On the newer model Fireproof Sentry Safes my locksmith recommended me To install batteries,
turn the electronic lock case to the right and remove. Insert four new batteries as indicated, replace the electronic lock case and turn to the left to reassemble.

Sentry Safe 1250. How to change the combination please?
Safes with dials are a little more complicated. NEVER close the door after changing the combination. Practice the opening sequence with the door open. If you did it wrong, you can reset and try again

Why won't my safe open? I have 3 keys that fit, door won't open . I don't know combination.
There should be a serial number on the safe. You can google the manufacturer and get a contact number, call them and they will be able to walk you through resetting the combination. But it sounds like you will need to replace the battery in it first
