So I want to check the connections behind the back box for the pinball I just got. The guy who sold it to me said he couldn't find the key. I was thinking I could unscrew the two screws holding the lock in place, but I don't know what kind of bit that is. I've tried star tips, Allen's, every different tip I could find and I don't have it, whatever it is. I'm afraid to try a flat head and a hammer because of the proximity of the glass obviously, and if I have to drill I will, but figured I'd ask for some help in here first.
