The screws stripped out while I was trying to attach this box to the outside of my house, then after 2 weeks, the lever used to open the box jammed, so that even with the right combination, it will not open.The "good" news is that it took me less than 60 seconds to break the box open with a screwdriver (no hammer required), so I got my key back without breaking a sweat.This is worthless and expensive. Even if it worked, it would be a piece of cake for someone to open it and get your key.
