<p>The cylinder lock assembly includes a cylindrical lock housing having an inner core extending between first and second ends. The inner core defines a core axis extending through the first and second ends. A lock cylinder is received in the inner core for rotational and axial movement in the inner core. The lock cylinder includes an axially extending key slot for receiving a key therein and a radially extending slot extending through the lock cylinder and intersecting the key slot. A rotation plate assembly is received in the radially extending slot and blocks at least a portion of the key slot. The rotation plate includes first and second rotation plate members which are movable relative to each other. A first biasing member engaging the first and second rotation plate members urges the second rotation plate member radially away from the first rotation plate member. The first and second rotation plate members define a space therebetween having a variable radial dimension for receiving therethrough the key received in the key slot, wherein upon insertion of the key through the space and into the key hole, the key engages the first rotation plate member to urge the first rotation plate member radially toward the second plate member against the urging of the first biasing member to allow the key to enter the key slot through the space.</p> |
