A casing includes a housing has a pair of spaced apart housing side walls and housing rear wall therebetween. A drawer slidably supported within the housing has a bottom, drawer side walls extending vertically from the bottom, and drawer front and rear walls extending vertically from the bottom. A key retaining lock is disposed in the drawer front wall and a rotatable shaft is connected to the lock and extends through an interior of the drawer to the drawer rear wall. A rotatable locking cam is connected to the shaft and located behind the drawer rear wall. A blocking member attached to the housing is located to cooperate with the locking cam to lock the drawer in a closed position. A stop block attached to the housing blocks the locking cam until the locking cam is in a position to cooperate with the blocking member to lock the drawer in a closed position.
