An axial tumbler lock comprises a casing and a lock cylinder mounted in a lock body and forming a shear plane. A plurality of axial tumblers normally block notation of the casing relative to the cylinder. When a key is inserted, key posts urge the tumblers into an aligned position permitting rotation of the casing and opening of the lock. The tumblers are disposed in a nonregular pattern and a plurality of dummy pins are provided indistinguishable from the tumblers making detection of the tumblers and unauthorized operation of the lock extremely difficult.
