Question about Sentry Fireproof Safe

1 Answer

Bolts on a SentrySafe A3860 are stuck retracted in the door.

The bolts on our A3860 safe appear to be stuck in the retracted position. I had trouble opening the safe this last time - it took several attempts to get the door open. Now the bolts on the door won't extend to lock the safe. I can push the individual bolts in slightly in the door, but they will not fully extend. The handle won't move them either. I'm thinking it might be something wrong with the handle or interior locking mechanism...?

I can't open the door, I have used the key and tried the combination. I hear the lock disengage but the door won't open. It appears to be stuck. How do I get it open?

You may have the same problem as me.
The bolts in the opening side may have sheared off of the ratchet arm that pulls them into the door. It's a casting using inferior quality metal.
I was lucky. The problem was found when the door was open.
The only way to open the door will be to turn the safe (with everything unlocked) so that the hinged side is along the floor and try tapping the top so the bolts drop into the door (the bolts are joined together).
If the safe has been secured and cant be moved get a grinder and chop the hinges off. With the hinge side bolts withdrawn the door can be opened. Sentry doesn't do this spare, so a new safe is required.

I have a sentry 1250. the door is stuck shut. The dialer won't move but the handle will. how can i fix this?

As a locksmith it sounds like the safe is unlocked and the handle is broken. try turning it on it's side and dropping it this might retract the bolts.

I have a sentry SO500. I know the combination but

A locksmith would try to replace the batteries. Sometimes you will get the green light but the batteries still will not have enough power to retract the latch.
