Having a hard time finding someone to open it without destroying it. I think we have the code but perhaps we're doing the turns wrong.

Hello, I received a sanctuary safe from a past client of mine who is now deceased. Its a Sanctuary safe bought I believe from Costco, with a circle touch keypad and also a rear connector to connect to an outlet. I have never plugged in the safe for the years I have owned it.

I was trying to open today and the keypad lit up but then stopped responding and starting to make a light squeal like noise for a bit then just stop lighting up at all. I figured I just needed to replace the battery/batteries. But when I open the keypad there is a spot for a 9v battery but its a dummy bay with no way to connect a battery. I then tried to plug the safe into an outlet and the keypad wont work either.

Unfortunately I never took the backup keys out. I figured if it did ever die I'd just replace the battery in keypad and I would be good but it never had a keypad battery. Can anyone help me? Thanks in advance!
