Never set the safe before

I am in the military and we bought one of your sentry safes and never used it before. Now that we are trying to use it we lost the instructions and the door is lock. But we never set a combination to it what can I do, Is it possible for us to get it open and to get the instructions sent to us?

SOURCE: How do I open the combination lock to my sentry home safe?

Locksmiths advise these Opening instructions for sentry fireproof electronic security safes. Insert the tubular sentry key into the lock to the left of the key pad. Turn the key all the way to the right until the plunger pops out. Press the five-digit factory code. The green Proceed light will come on. Pull the handle down; to crack the sentry door open.

That didn't take you long to lose it. You can get it from Sentry direct. You should also have a key on larger ones? Then you press the reset button inside and set a new one.

Dead battery and safe wont open

battery cover can be removed from outside. replace batteries and try again but if you remove batteries more than 1 or 2 times in a row, safe will revert back to a factory setting. That number should have been on your instruction sheet when bought. Good luck though, I bought a Sentry A3821 and it's only 5 years old and won't open.. After help from sentry I was told solenoid is bad and no longer made. So I now have a piece of junk bolted to my floor

Sentry Safe (DSW3607 Model) Won't Open

I finally ignored the poorly-written instructions for programming a personal code and simply entered the factory code first and then pressed the prog/enter code button.  The safe opened.  The instructions tell you to push the prog/enter code first and then enter the factory code or personal code to open the safe.  Wrong!  Do it my way should this problem happen to you.

Safe SENTRY S3877 can not open the door

The door lock could be jammed try shacking briskly to losen lid and latch! akso it may have reset itself and the combo is no good no more and back to the origanal setting it had when you bought it ! ( if its a 911 you can put a screwdriver in where key goes and turn hard counter clockwise)
Good Luck!
