Locks only keep honest men honest. I have a name brand fire safe I keep my important documents in. Of course I lost the key and needed a car title or my DD-214. The car thief's screwdriver (that's another story) was nearby and the over foot long lever pop the safe. Like it was said by superc previously, my gun safe keeps my 4 year old grand son at bay. And that is not an easy thing to do!
