A DOUBLE CYLINDER LOCK
A cylinder lock comprises a cam for actuating the bolting means of a door; the cylinder lock further comprising two ends, a first end positioned on a first side of the cam and a second end position on a second side of the cam, substantially opposite said first end; wherein at least said first end comprises a keyhole which, when a key is inserted, actuates the cam to lock or unlock the bolting means of the door; wherein the lock further comprises a drive assembly for displacing said cam when a key is inserted, and a securing means which is displaceable, by said drive assembly, between a first position in which the securing means engages with the cam to prevent its movement, and a second position wherein the securing means disengages the cam to allow movement of the cam; whereby, in use, when a key is not present in the lock, the securing means is in the first position to prevent movement of the cam and thus the bolting means of the door.
