Abstract
A key has a blade formed with a part-cylindrical face and with a pair of relatively shallow, outwardly open, and generally parallel but spaced grooves formed in the face extending generally longitudinally in a nonstraight path and a relatively deep and outwardly open groove formed in the face and extending generally longitudinally in a nonstraight path generally nonparallel to the shallow grooves. The grooves each have a plurality of control positions at which they extend substantially parallel to the blade and are inclined to the blade between the respective control positions. The control positions of the shallow grooves are transversely aligned and staggered relative to the control positions of the deep groove
