My son is going to buy a gun safe. He is thinking about one w/ key pad. I advised him to go with the combination. A gun safe is a life long thing he will own. Realistically electric solenoids will wear out and fail. I have one that went bad. Luckily I have a skeleton key that hangs in safe #1 and can open it. Now my keypad proudly has a NRA sticker over the numbers. Anyone have input to settle the arguments?
