Temporary key template

Abstract

A kit and method for constructing a temporary key template from a key code of a lock having pin tumblers is disclosed. The temporary key template is used as a master in order to make a permanent duplicate key having appropriate serrations from a suitable uncut key. The kit includes a converter blank key having an elongate bar in which a plurality of apertures are provided. These apertures are spaced at predetermined distances from one another which correspond to the respective distances between the pin tumblers of the lock. A plurality of different pins are provided which are adapted to be inserted into any of the apertures so that a predetermined upper portion of the pin extends above the elongate bar. The particular pin need for an aperture is determined by the key code so that by filling the appropriate apertures with appropriate pins, a temporary key template is constructed which is easily duplicated on a conventional key duplicating machine. The converter blank key preferably includes a stop member from which the elongate bar extends and a mechanism for holding the pins in the apertures. The diameters of the upper portions of the pins is preferably slightly smaller that the spacing between the apertures where the apertures are evenly spaced.
