If someone attempts to open the locked safe by forcing the safe handle to the open position it can strip the plastic gear. So even if you have the correct safe code and the batteries are fully charged the safe will not open. If you can lay the safe on its side (hinge side on the floor) gravity and banging the side of the safe with a hammer may cause the bolts to unlock. Unfortunately, if this doesn't work you will need a locksmith to open the safe.

Good luck.

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

Yes I agree. Their key lockable products are much much better.
