A cylinder lock protection device is provided in which a shutter plate is housed in a casing having a mechanical key insertion hole, the shutter plate being capable of opening and closing the mechanical key insertion hole, wherein when restricted state release means (65) releases the restricted state due to closed position restriction means (56), the shutter plate (36) is automatically operated from the closed position to the open position by urging force applied from open direction urging means. In a state in which the shutter plate (36) is at the open position, when the mechanical key inserted into the cylinder lock side from the mechanical key insertion hole is pulled out of the mechanical key insertion hole at a predetermined pivoting position, closed position side urging force control means (94) allows closed direction urging means, which exhibits urging force that is larger than that of open direction urging means, to make the urging force act on the shutter plate (36), the urging force from the closed direction urging means thereby acts on the shutter plate (36) and the shutter plate (36) automatically operates to the closed position. Thus, the shutter plate automatically moves between the closed position and the open position, thereby enhancing the ease of operation.
