ABSTRACT:
A lock and key set comprises two cylinder locks (1,2) each having a cylinder (3,3'), a barrel (4,4') rotatable in the cylinder, and a set of tumblers (9,9') radially movable in the cylinder into and out of engagement with the cylinder, and a key (20) having a bit (21) which can be inserted into the barrels of both locks and provided with two sets (23,24) of cam surfaces (22). The sets of tumblers (9,9') in each lock are movable by a respective one of the sets of cam surfaces in response to rotation of the key bit in clockwise and anticlockwise directions, so that when the two locks are incorporated in doors on opposite sides of a vehicle, they are actuated with opposite movements.
