A cylinder lock device including: a body housing having a bore, with a direction of elongation defining an axial direction for the device; a rotatable cylindrical plug in the bore, the plug having an axially extending key slot from at least one end of the plug; a plurality of driver pins configurable substantially perpendicular to the key slot and located within the body housing and substantially outside of the plug; a plurality of tumbler pins corresponding to and positionable substantially collinear with each one of the plurality of driver pins and substantially inside the plug, the tumbler pins displaceable by a key to bias the driver pins to enable rotation of the plug, the driver pins adapted to displace the respective tumbler pins; and a displacement mechanism being deployed within the body housing and adapted to displace the plurality of driver pins thereby selectively enabling rotation of the plug when no key is present in the slot.
