A cylinder lock with a first lock actuator 104, a second lock actuator (Figure 3, 108), a cam (Figure 5, 107) between the first and second lock actuators and arranged for rotation about an axis between a locked and unlocked position, and a clutch mechanism 110 arranged to selectively engage the first lock actuator with the cam for rotation therewith. A cylinder lock wherein the clutch mechanism 110 comprises an axially movable clutch body (126 figure 1a) having a tab 138 arranged to engage a recess 136 on the cam where the tab is axially movable relative to the body. The tab may be resiliently biased towards the cam and may be movable from an extended position to a retracted position in which it is partially contained within a recess in the clutch body. |
