ABSTRACT:
A lock (10) having inductive key detection includes a lock mechanism (14). A detector member (20) is movably disposed proximate the lock mechanism (14) such that the detector member (20) moves when a key engages the lock mechanism (14). The detector member (20) has a magnetic portion (24). An antenna (30) is disposed proximate the detector member (20) such that movement of the detector member (20) induces a signal in the antenna (30). A detector (42) is coupled to the antenna (30) and is operable to detect the signal in the antenna (30).
