In a cylinder lock protection system in which a shutter plate automatically returns from an open position to a closed position in response to a mechanical key being withdrawn from a key hole, resilient means (57), first and second engagement members (58, 59), and cam means (60) for moving the engagement members (58, 59) are housed within a casing (22) so that they move along a plane perpendicular to the axis of a key hole (28), and the cam means (60) makes the first engagement member (58) engage with a shutter plate (34) in response to movement of the shutter plate (34) to the open position, makes the second engagement member (59) engage with the shutter plate (34) in response to the mechanical key (33) being inserted, releases the engagement of the first engagement member (58) with the shutter plate (34) in response to pivoting to an ON position, and releases the engagement of the second engagement member (59) with the shutter plate (34) in response to the mechanical key (33) being withdrawn. This enables the cylinder lock protection system to be formed compactly without the necessity for forming a long mechanical key.
