ABSTRACT:
A key-operated cylinder lock including a cylinder lock housing, a cylinder lock core assembly rotatably located within the housing, and an outwardly biased, radially movable lock bolt. The cylinder lock housing includes a cylindrical side wall encircling an axial cavity for receipt of the cylinder lock core assembly and a pair of opposed axially extending arcuate lugs extending inwardly from the cylindrical side wall into the axial cavity. The cylinder lock core assembly includes a core insert retaining several hardened key guides and biased tumblers. The core insert rotates within the cylinder lock housing to transfer force between a key inserted into a key entryway and an eccentric stud riding within a cam cavity defined within the lock bolt to effect radial movement of the lock bolt in conjunction with rotational movement of the key. The core insert includes a pair of opposing fortified wings for abutting the arcuate lugs of the cylinder lock housing to resist relative axial movement between the core insert and the cylinder lock housing. A radially extending hardened cylindrical pin is embedded within the core insert behind the hardened guides and in front of the eccentric stud to deflect an intrusive device away from the eccentric stud and into the hardened guides.
