The present invention relates to a pin tumbler cylinder lock having a cylinder casing and a plug selectively rotatable in the casing, and a plurality of driver pins and associated tumbler pins rotatable about their longitudinal axes. The cylinder lock includes a plurality of parallel circumferential tracks formed in the cylinder casing. Each of the tumbler pins is adapted and configured to seat in the plug and includes a track engaging element arranged to selectively engage one of said tracks. The tumbler pins are arranged to align both vertically and horizontally with matching depressions in a symmetrical key, in order to permit the turning of the plug in the cylinder casing when the key is turned. |
