Abstract: A pin tumbler lock having a cylindrical lock housing receiving a rotatable plug shaft with a front barrel and a rear barrel secured thereon, a center barrel secured in the lock housing and an index ring stationarily mounted in the lock housing and encompassing the front barrel. The front, center and rear barrels have a plurality of axially extending passages receiving tumblers, change tumblers and locking pins. The index ring includes a pair of oppositely disposed radial openings normally aligned with radial openings in the front barrel and receiving a pair of inwardly biased retaining pins having rounded inner ends cooperating with depressions in the surface of the key. Rearwardly of the retaining pins is a second pair of radial openings in the index ring normally aligned with radial openings in the front barrel to receive inwardly biased drivers and antitorque pins also cooperating with the exterior surface of the key. The plug shaft within the front barrel is provided with a plurality of circumferentially equally spaced longitudinal ribs which cooperate with longitudinal grooves on the interior surface of the key so that rotation of the key provides simultaneous rotation of the plug shaft as well as the front and rear barrels and a lock bolt on the rear end of the shaft if the retaining pins, antitorque tumblers and axial pin tumblers are properly oriented by the key.
