Patent Images
1. An electronic lock comprising:
- (a) an elongate cylinder housed within a shell, and rotatable about a longitudinal axis relative to said shell;
(b) said cylinder containing an electrically-controlled locking mechanism including a locking member selectively movable alternatively toward engagement with said shell so as to interfere with rotation of said cylinder relative to said shell, or away from engagement with said shell so as to permit said rotation;
(c) said cylinder having respective front and rear portions located at different positions along said longitudinal axis;
(d) said front portion being engageable with a key so as to enable said key to rotate said front portion relative to said shell, and said rear portion being detachably interconnected with said front portion so as to be rotatable by said key in unison with said front portion; and
(e) said rear portion containing said locking member.
