Abstract

A dual cam, reversible key includes first and second patterns of notches in first and second edges of the shank of the key on a common side of the key shank of the key, providing a dual cam key. The patterns of notches are formed to have complementary symmetry and to make the width of the shank constant along at least the portion of the shank that includes the notches. The first pattern of notches is identical with the second pattern of notches insomuch as they are 'parallels' to each other. The key operates tumblers each of which has an opening defining a pair of staggered generally rectangular windows, each of the windows defining cam surfaces for accommodating the dual cam, reversible key. Also disclosed is a method for making the dual cam, reversible key.
