Abstract

Cylinder locks (1A, 1B) for use in the locking of doors (2) on opposite sides of a vehicle, each have a single barrel (15; 30) which carries tumblers (16; 31) that abut internal shoulders (23) of the lock casing (7) to obstruct turning of the barrel (15; 30) in an unlocking sense (different for the two locks) until the tumblers (16; 31) are withdrawn into the barrel (15; 30) by initial turning of an inserted key (5). The barrel (15; 30) in each case is free to turn in the opposite, locking, sense without any obstruction, turning in both senses being opposed resiliently by a coiled spring (24; 40) that embraces a spindle (10) of the barrel (15; 30) externally of the casing (7). The tumblers (16) of one lock (1A) are spaced by a bush (18) forwardly within their barrel (15) as compared with the tumblers (31) of the other lock (1B) so that different sets (A, B) of the cuts (38) of the common key (5) engage the tumblers (16, 31) of the two locks (1A, 1B).
