Or cut the safe and buy better brand.
This is why I would not own a safe with an electrical key pad.
It was a shock to say the least, right out of my easy chair across the rug then touch the keypad is not good.Must have been one heck of a static electricity shock.
I have a digital key pad too but my safe was a gift from my brother. I have always been in the habit of touching the safe handle, before I reach for the key pad.
I got lit up good from static discharge from a UH1 Iroquois helicopter once, due to another guy's lack of attention to detail but that's a whole other story.
Best of luck to you!
Last safe I bought had an electronic lock. Bought a s&g dial for $110 and changed it out. Take the door panel off and the change out is easy, hole pattern was the same on mine. There was one hole that was only drilled from the factory that I had to run a tap into.
That's what I would look into once you get it open.
