Zusammenfassung:A lock assembly includes a plug with a keyway, primary pins aligned with the keyway, a sidebar, secondary pins adjacent the keyway, and at least one supplemental sidebar control element for controlling movement of the sidebar. A key blank has a key blade with a primary top edge to receive primary bittings for controlling the primary pins, a rib to receive secondary bittings for controlling the secondary pins, and at least one shuttle pin. The shuttle pin engages a multi-level ridge within the keyway to move the shuttle pin from a retracted position to an extended position in which an end of the shuttle pin actuates the supplemental sidebar control element.
