1. Insert a paper clip or pen point into
the small hole of the battery cover located
directly below the keypad. Push in while
sliding cover to the right (Fig. B).
2. Disconnect and remove battery holder.
• Insert 4 new AA batteries (not included)
to power this lock.
• Reconnect the battery holder and put back into proper
position. Slide battery cover back in place.
NOTE: The yellow LED will light when the batteries need
to be replaced.

You can also get the manual here on link below. page 1 tells you how to replace battery.

Safe will not open


Once you get the error light that means you are entering a user code that was deleted when the batteries went dead . Simply use the master code in your owners manual to open the safe. Reprogram new user code instructions bottom of this page.

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:

We have a S3877 Sentry safe. The battery appears dead so I can't use the code. I also have the key but since the battery is dead it is no help. What can I do?
