SOURCE: Forgot Digital Combination of Sentry Safe Model #SO500

They should be able to help. I would try calling first, to avoid paying the $12 to retrieve the combo, but with the serial number of the safe, they SHOULD be able to help you over the tele.

SOURCE: know combination, but cannot open sentry safe 1250

Make sure you are working the dial properly for this type of safe. With the door lever fully counter clockwise, turn the dial clockwise a couple turns to start. It should turn quietly. Then turn the dial counterclockwise (LEFT) to the first number in the combination. Now turn the dial clockwise (RIGHT) a full turn passing the first number again, and additionally clockwise to the second number. Then turn the dial counter clockwise from the second number directly to the third number. Try to open with a sharp movement of the door lever clockwise. If this does not work the first time try adding or subtracting ONE to each number in the combination in case the mechanism is worn. If it still does not work it is time for a drill and a power saw to cut the thing open!

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.

SOURCE: sentry safe S3877 have key and know combination but battery dead

Our safe had a philips screw at the bottom of the keypad (facing downward), not a paperclip hole as some do. To replace batteries, unscrew this setscrew and twist the face gently. Replace the 4AAs and reinstall faceplate/fingerpad. Should work.

How do I open a sentry s3877 safe when the battery is dead and safe is closed


The factory code combination to your electronic lock will remain in the memory of the unit - even if the batteries go dead. Any use programmed codes will be lost if the batteries lose power. The Sentry programmed factory code is always your default code.

If you do not know your factory code, you can follow this link for your combination retrieval:

Sentry safe v260 . have both keys but forgot the combination. how can i over write it?


If you have a "3 number combination" or have a "4 number combination you that you have NOT changed", you can send in your serial number in a notarized letter and $8 to: Sentry Group, Dept 200, 882 Linden Ave., Rochester, NY 14625-2784. (this info is in your Owners Manual under Lost Keys or Combination) If you don't have your Owners Manual you can download it from: http://www.sentrysafe.com/products/productDetail.aspx?s=130

If you have a "4 number combination" and you HAVE changed it from the original cobmination, the only solution you have is a locksmith.

Changing the combination


These sentry safes dial combinations are not built to be changed as they have no key change hole. Switching the order of the tumblers could be done by a trained locksmith. I would suggest buying the electronic sentry safes as these safes can be reprogramed.
