Abstract
A lock and key combination providing extra code combinations. The lock has a housing and a cylindrical key plug with a keyway and at least side locking tumbler. The side locking tumbler has, at its rear side, a tongue which will fit into an associated recess in a side bar. The outer surface of the tongue is shaped as a groove between two vertical edge portions. One of these edge portions will make contact with the sidebar, adjacent to an entrance opening of the recess in the sidebar and thereby stop the tongue from entering into the rectangular recess if the side locking tumbler is rotationally misaligned. Because of this, it is possible to design the cylinder lock with a large number of predetermined code positions for each side locking tumbler. An associated key with a key blade having a wave-like side code pattern, will have, for each side locking tumbler, a selected one of a large number of predetermined different code positions.
