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 https://en.shpock.com/i/WgwKN4clWgXDaZ53/ ) 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.

Trying to reset an ATV DVR admin password manufacturen in2015.
The DVR has a Factory Reset switch to the left of the Alarm Output connectors
on the rear panel. This switch will only be used on the rare occasions that you want
to return all the settings to the original factory settings.
When using the Factory Reset, you will lose any settings you have saved.
To reset the unit, you will need a straightened paperclip:
1. Turn the DVR off.
2. Turn it on again.
3. While the DVR is initializing, the front panel LEDs will blink. When the front panel LEDs blink,
poke the straightened paperclip to the unlabeled hole in the left of the Alarm Output connectors.
4. Hold the switch until all the LEDs on the front panel are lit.
NOTE: When the DVR successfully resets to factory defaults all the LEDs on the front panel flash
Release the reset switch. All of the DVR's settings are now at the original settings it had when it
left the factory.
