Manual For Sentry Safe 1250
I have a Sentry Safe that I purchased from Sam’s a year or two ago (too lazy to look it up). My wife recently tried to open it and, even though it agreed with the combination that was entered, the electronic opener refused to release the lock. Since this safe can only be opened with an electronic code, this is a BAD situation! I first tested all four batteries with my handy-dandy battery tester and they all passed with flying colors. I could hear the actuator trying to work each time I entered the code. I even tried the “master” code. Being somewhat mechanically inclined, I decided to whack on the front of the safe with my fist (didn’t think I would hurt it) after entering the code.
