Question about Sentry Fireproof Safe

2 Answers

My sentry brand safe is malfunctioning. The door is open, but the bars that lock it are engaged and extended (as if the door were shut and locked). When I key in the code, the green light comes on, meaning that the handle should turn and the bars should retract but they don't move. Therefore, I can't shut the safe. Does anyone know how to reset the passcode?

Try unlocking the round key hole. It should pop the mechanism out. While it is out, try your password again and it should retract the bars.

My sentry safe, number bx-887566, is stuck in the open position. The lock is engaged and the key won't turn. How do,I fix this??

I did this on my own safe. Different brand but you can try. Somewhere on the door , look for a latch or pin or rod that you can push in.These are usually triggers that allow the lock to turn only when the door is closed. Somehow, you have locked it with the door open (as I did). Press in any of these and try turning the lock. It will be tricked into thinking the door is closed and allow you to turn the key. Good luck

I have a Sentry safe S5741. I have the electronic combo and the key. The door to the safe was locked with the door open. Now the door will not unlock to shut the door. Is there trip to reset the door? Is...

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.

My Sentry safe MS0100 combination dial will not turn. I can open the door but can not turn the dial to lock it.

If the safe is brand new.. you must first remove the locking screw at the base of the combination lock dial lockcase.. discard the screw.. Make sure you have the owners manual with the sticker and default lock code nearby before locking the safe.

The factory has a preset combination code that cannot be deleted. It is on the owners manual. You can use that code if your codes have become compromised.

Also ensure the batteries are fresh. This may also be the problem.

Anything beyond this will require assistance from Sentry. Your serial number is on the side of the door. Have that ready.

Best of Luck

Can not lock door, works fine when open but will not lock when closed, handle wil not go up all the way. Sentry A3150


There might be 3 problems:
1. The door is not aligned anymore.
2. There is something in the frame where the lock goes in.
3. There is internal malfunction.

If you are sure about 1 and 2, you need to take it for service/repair.
