<p>A multi component key (1) including a primary component (7) having a shank portion (3), a contoured edge portion (4) including a step (21), and a head portion (2) is useful for granting conditional access to a facility. One or more secondary components (8) are also included, each also having a shank portion (3), a contoured edge portion (4) and a head portion (2). The primary component (7) and the one or more secondary components (8) form, when assembled together, a complete key (1) for opening a lock. Removal of the primary component (7) from a lock is facilitated by the assembly of the one or more secondary components (8) with the primary component (7); however removal of the primary component (7) from a lock is prevented in the absence of the one or more secondary components (8) because the step (21) abuts a pin of the lock.</p> |
