ABSTRACT:
A key retaining device for capturing and selectively locking therein a portion of the working section of a key. When the key is locked in the device, its handle section is visible so that the presence of the key can be instantly determined without unlocking of the apparatus, yet the key cannot be removed from the device until unlocked with a master key. Retention of the key within the housing is accomplished by a clamping mechanism employing a pair of blades which reciprocate toward each other to clamp the working section of the key therebetween and reciprocate away from each other to permit free removal of the key, the reciprocation resulting from manipulation of the master key in a lock assembly.
