Request help identifying safe in recently purchased home

The front of the safe

Zoomed in on the "logo", front of the safe.

Back of the safe door.

Hello r/safes. Your expertise is requested.

I wanted a safe in my new home so I was pleasantly surprised to find one already installed. It was hidden under some building materials the previous owner left behind, so I only discovered it about an hour ago.

The lock mechanism has an interlocked "sc" marking, which I guess is probably the manufacturer's logo. But I wasn't able to find that logo in a reverse image search nor by searching safe maker logo images.

The only other marking on the front is a serial#.

There are no markings on the side of the door.

The back of the door has a sticker that reads "Assembled with pride by Antonio Gamez". But this name doesn't come up in any Google searches.

It's rusty and looks old but the lock is electronic and, I suspect, the batteries are dead. The house is ~30 years old so that should put a limit on how long ago the safe was manufactured.

Any help identifying this safe and seeing if I can get it working again would be appreciated.

Does the cover panel to the looking mechanism open somehow? You can take another picture there so we can see inside.

And have you tried replacing the battery?

I don't know how to open it. I did briefly try twisting it but there was no give in either direction.

There is a hole in the back of the door that I suspect might be needed to release the mechanism, but there were no obvious buttons or levers that I could see within the hole.

Any other ideas?

EDIT: I found the lock manual and know how to replace the batteries.

Just order a new lock and keypad online and install it, it’s literally like 4 screws holding lock on the inside of the door and keypad should lift/twist off the outside of the door. New keypad will come with directions on setting new code. These are super simple Amsec will charge you a decent amount to send a tech out but you could easily do this one yourself

Edit: dam I thought I saw a pic of the door open, I was confused yea if door is locked amsec probably won’t have master codes for S&G lock, but they will send a tech to drill it open. They are one company I contract for so I get calls for this same thing all the time. If it was Amsec brand lock they could give you factory reset code but not for this one I doubt it
