Hi there,

If you have entered the correct combination but the safe won't open, then the mechanism may be jammed - try hitting the door with a rubber mallet to help loosen it up.

I have already tried this/ have also put safe on its back, still nothing. I was looking to have you tell me that with a crowbar or with a metal blade and skillsaw I could cut it open without damaging the contents. I need to know where I should cut if necessary, or where on the door I should use a crowbar.

Hi,

Unfortunately it is not that easy - these safes are designed to be very secure.

I would recommend getting in touch directly with Sentry to firstly check that you are using the correct combination:

I have been using this combination for 10 years, it just stopped working. I was looking for some advise on where I would put the crowbar or where it is easiest to cut the safe open without damaging the materials inside.

If the combination has been unlocked but the door is stuck closed then you can try getting the crowbar in close to where the four bolts are - see the following image:
