Abstract
Abstract A key assembly which can be assembled to a specific code by snapping together the different parts of the key assembly. The key assembly includes a tubular, cylindrical barrel which has a plurality of spaced apart elongated grooves formed in the exterior surface of the barrel. A hole connects with each groove. A pin is to be mountable within each hole. An insert selected from a grouping of a plurality of different lengths of inserts is to be mounted within each groove with the pin for that groove being located within an appropriate opening formed within the insert thereby longitudinally fixing in position the insert with respect to the groove. A collar is then exteriorly mounted on the barrel about the inserts and fixed in position thereby preventing disengagement of the inserts from their respective grooves. A handle is mounted on the barrel.
