S3877 Sentry safe will not open, get green light but lever

I have had this safe for 5 years and never had a problem, today I put in the 5 digit code and it accepted and went green, heard the normal click noise yet the lever would not open, it was thought it never opened.

I am confused because the everything works like normal but the lever will not turn now as though it is bad. I replaced the batteries and it did not help. The code still works and it goes green yet it will not open.

Please advise...Thank you

It sounds like the selinoid went bad or stuck this pulls the plunger down to release the handle, you might be able to take out the key pad and determine the 2 wires that go to selinoid jumper them out with a nine volt battery good luck. p.s. this could ruin your safe, be carefull. bigds keys

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:

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.

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.

Safe SENTRY S3877 can not open the door

The door lock could be jammed try shacking briskly to losen lid and latch! akso it may have reset itself and the combo is no good no more and back to the origanal setting it had when you bought it ! ( if its a 911 you can put a screwdriver in where key goes and turn hard counter clockwise)
Good Luck!
