Question about Sentry Fireproof Safe

Error light comes on when keying combination code

Model A3750 fireproof safe, always has worked up until tonight. As soon as we put key in, turn to right, button pops out, then when we enter code, error light comes on and blinks as if we have entered the wrong code. Code is correct.

    Thank you for helping me. I though that it might be the batteries, but I forgot how to get to them to change them. After changing them it worked perfect. Now all I need is the papers that came with my safe I have lost them in moving.

How do you open a sentry 1250 combination safe? I have the number


Locksmiths agree If your safe doesn't have a key, skip Step 3.
Turn the dial to zero.
Insert your sentry safe key and turn it until the plunger pops out.
Turn the dial to the left (counterclockwise) three times to the first number of the combination (pass the first number of your combination two times, stopping on it the third time).
Turn the dial to the right (clockwise) two times to the second number of the combination (pass your second number once, stopping on it the second time).
Turn the dial to the left to the last number (stop the first time on your last number).
Pull the handle down; cracking the Fireproof Sentry Safe open.

My combination to s3877 works, but key button is pressed by accident and I can't find the keys to unpop it. How do I get it open. Light turns green after inputting the code, but level is unmovable.


You will need to contact customer service (either in the UK or US) for the replacement keys - without the keys you can't get into the safe. The key barrel is a secondary lock and needs to be unlocked before you can use the digital or dial combination.

Key is not working


Nice looking safe. You can download an owner's manual from sentrysafe.com.
Some safes have provisions for supplying power to the combo in event of battery failure.
I don't know how it is supposed to operate with key.
