SOURCE: know combination, but cannot open sentry safe 1250

If you know the combination:

1) Turn the dial to the left a few complete rounds, then stop on 1st number.
2) Turning the dial to the right, pass up the 2nd number once, then stop on it on the next round.
3) Turn the dial to the left directly to the 3rd number then stop.

The handle should open now.

SOURCE: Sentry Safe (DSW3607 Model) Won't Open

I finally ignored the poorly-written instructions for programming a personal code and simply entered the factory code first and then pressed the prog/enter code button.  The safe opened.  The instructions tell you to push the prog/enter code first and then enter the factory code or personal code to open the safe.  Wrong!  Do it my way should this problem happen to you.

White powder is leaking out of the door of my Sentry A3821 safe. What is the composition of this powder? Is it asbestos?


Sentry uses a proprietary compound concrete/water and some other "secret ingredients".

Sentry claims there is no harmful or toxic products used it's line of safes.

Seal the crack/hole..with silicone or gorilla glue etc..

Best of luck

I need to find out what the factory code is to my sentry safe model a3821 they said you had my solution and i paid but have not seen a solution yet@@@?????


Here's the link to the Owner's Manual for the safe. See the bottom right of page 3 for installation of new batteries. This model has the batteries outside of the safe so there is no reason to look into for the batteries. Once you follow these steps, you will have your resolution. http://www.sentrysafe.com/pdfs/OwnersMan uals/501664.pdf Reference: http://www.sentrysafe.com/pdfs/OwnersMan uals/501664.pdf

Dead battery and safe wont open


battery cover can be removed from outside. replace batteries and try again but if you remove batteries more than 1 or 2 times in a row, safe will revert back to a factory setting. That number should have been on your instruction sheet when bought. Good luck though, I bought a Sentry A3821 and it's only 5 years old and won't open.. After help from sentry I was told solenoid is bad and no longer made. So I now have a piece of junk bolted to my floor

Somehow can open my sentry s3877 with the keypad.


A Safe and Vault Tech Will confirm that once you change the batteries the user code will erase and you will now have to enter the factory default that is in the owners manual and then use the programing instructions to program a new user code.

Sentry 1610 safe - battery is dying?


I have 2 Sentry 1610 Safes. A fresh alkaline battery MAY open the safe once (maybe twice), and then the same problem. I have a variable DC power supply that I hook up to the battery terminals, set to 9 volts and increase the current until the keypad responds & the deadbolt releases. Sentry has no solution for this problem, as this model is too old & they have no parts or troubleshooting. If you know someone with a small DC Power Supply, you can get your safe open / closed.

How to cahnge the battery on a sentry safe


There is a small opening on the front number panel of safe. Use a small hex screwdriver or pin to insert into opening. It will open up the front panel (slide panel to right to take off) showing you 4 AA batteries. Just replace and close panel. Very simple to do. I wish the manual show me how. Instead of trying to figure it out for hours.
