You will need to either break it open, or go see a locksmith.

How do i change the battery on a Nutool SF10 electronic Digital Safe

Don't know this model (sounds American) but in general batteries can only be replaced once the safe is open.

For emergency access (sensible) models have a couple of externally accessible terminals onto which you press a 9 volt battery and then open with your combination so you can get to the internal battery to change it.

Looks like this model (from a pic found online at ) has a key over-ride to unlock for emergencies. In that case it's unlikely to have an external battery connection.

Also from a pic online at
the battery is accessed (once opened) via the battery cover clearly visible!!! on the back of the door.

If you haven't noticed this my guess is you have not opened it, in which case....

If you don't have a key then chuck out the safe.

My reasoning is if you can open it without key or combo then it's a useless junky safe, so ditch it. If you can't, then the only way to retrieve the contents is to cut it up, and then you will have to ditch it anyway.

CAVEAT: URLS go dead, so the picture may not be valid by the time you read this.
