Abstract
An electromechanical lock system has a lock cylinder including a body, a rotatable core forming a key passage, and carrying at least one magnet, tumblers engageable between the core and the body and shiftable between positions blocking rotation of the core in the body and freeing positions permitting such rotation, a sensor juxtaposable with the magnet in an angular position of the core in the body, anda coupling member juxtaposed with an inner end of the core, forming an inner extension of the passage, and rotatable in the body independently of the core. A mechanically operable element is coupled mechanically to the coupling member and an electrically operable element is coupled electrically to the sensor. A long key engageable in the passage has a bitting fittable with the tumblers to set same in the freeing positions and is of a length sufficient to reach into the coupling member so that insertion of the long key fully into the passage and subsequent rotation of the key turns the core and the coupling member to operate both the mechanical and electrical elements. A short key engageable in the passage has a bitting fittable with the tumblers to set same in the freeing positions and is of a length insufficient to reach into the coupling member so that insertion of the short key fully into the passage and subsequent rotation of the key turns only the core to operate only the electrical element while not operating the mechanical element.
