ABSTRACT:
An improved key safe for a door wherein the door has a hole therethrough. A hollow key holder is shiftably mounted in the hole. A spring exerts a bias force against the key holder in the hole of the door so that the key holder and key held thereby will be automatically ejected into an adjacent room and become completely inaccessible to an intruder. Ejection of the holder occurs when a hold-down means at the opposite end of the holder is forced off the holder in any manner, such as by using a crowbar, screwdriver or the like. The hold-down means will preferably be an O-ring seated in an annular groove at the opposite end of the holder. When unseated from the groove, the hold-down means moves off the holder, thus permitting the holder to be projected off the door and into the adjacent room under the influence of the bias force of the spring. Since the door is locked, an intruder will be prevented from reaching the key for unlocking the door.
