Sentury Fire Proof Safe 1250

Good morning,

We have lost our combination to the safe during our move. Is there anyway we can re set the combination??? The door to the safe is open but is in a locked position.

We have a combination lock with a handle and the only information I have on the safe is that it is a Sentury Fire Proof Safe 1250; bought about 10 years ago.

Any help would be great!!!

Thank you,

Keith Barker

    Sentry has a pretty good website. Take a look at this link:

    If you have the serial number for your safe and you never changed the original combination, it looks like they may be able to give it to you.

    I tried to look up the instructions for the 1250 on they Sentry website, but they don't appear to be available any longer. If I were you I would call Sentry to see if they can help you reset the combination or if you'll need to pay them for the original combination. Good luck.

Is there any way to crack the safe by feel, ive seen it done before and have some experience in opening locks with pin tumblers, but not wheel tumblers. i can find the notch in the third wheel at around 10-15 but i dont know where to go from there. I would not be using this information for any illegal use, i just need to open my safe on my own, and soon, thank you.

    Noah is right the best thing to do is contact Sentry. The serial # should be a long sticker on the lower part of the safe just under the door or sometimes on the side.

Remove the back plate. Then turn the dial 4x to the left all wheels should be moving now. Look for the first gate (a small opening in the wheel) on the wheel closest the safe dial. When it's lined up with the fence from the handle. Look and write down this # now dial right until the next wheel is picked up. Doing the same as before. Again change direction and write down the number. Do this until all numbers are recorded. Turn the handle and if it works, keep the door open and try it from the numbers you have. It will be different on 4 and 3 wheel packs but same idea. Turns should be 4321 alternating L and R. If this doesn't work goto local locksmith. Do not shut and lock door till you are sure you can open!!!

I concur with ohiotom but I will use this as a suggested solution in order to get this off the board.

You have to contact Sentry directly to get another combination

All you have to do is find your owners manual the sentry safe combination was posted in. Unless you locked it the safe as happens all the time. After all that is the safest place for it right. Or you can just call a locksmith service tech

I have a Sentry safe model #1250, but I have lost the combination. How do I retrieve the combination?

If you have it and it's not yours, give it back to the person who does have the combination.
Otherwise go through all the possible combinations until one works.

If it saves you money, use the Yes Machine that would be used on it in case of fire, and buy another safe you can remember the combination to.
