I have a G7311 (| Sentry® Safe | G7311 Gun Safe) gun safe. It's obviously more of a "cabinet" than "safe," but serves it's purpose (so we can avoid the comments of "you should get a better safe" or "you asked for it by buying that") and I understand that. At this point in my life and collection, it's all I really need. Now, with all that said, I purchased it a couple weeks ago, about a week ago the electronic keypad stopped opening the door (it worked fine before). It does have a key override, so I can still get in, but not by using the electronic keypad. The keypad is obviously getting power, as the green and red lights work, appropriately (if I push a number, the green light comes on. If I input the correct code, the green light comes on. If I input the wrong code, the red light comes on). So, I know it's getting power. I called and talked with Sentry and they believed it could be the battery pack/wires had a problem, so they sent me out a new battery pack and wires. I replaced those and am still having the same problem. At this point, I believe the problem is either the circuit board or the unlocking mechanism. Anyone have this problem before and know the remedy? I will be requesting Sentry send me a new circuit board (fat chance of that I am guessing) and/or a new locking mechanism (not sure the actual name of the component) and see if that works. I really don't see how it could be anything else (except possibly the keypad itself). So all-in-all, three possible components. Since the model is discontinued, I purchased the last one at the store. Sure, I could take it back, but then I'd have to unbolt it and drag it back to the store, and I would have to get something else. For now, I'm actually okay with the safe, I just want it working again and there's only so many components that can go back, so I figure I could just as easily fix it. Thank you.
