A second locking device ( 68 ) includes a member ( 32 ) moveable between a first and a second position wherein when the member ( 32 ) is in the first position the lock is locked and when in the second position the lock is unlocked. Generally the first locking device ( 52 ) is key operated and the second locking device ( 68 ) is driven by an electric motor ( 72 ). The first locking device ( 52 ) can operate the lock independently of the member ( 32 ) and regardless of its position and when used to lock or unlock the lock can decouple through a clutch mechanism ( 80 ) the second locking device ( 68 ) from controlling the lock.</p> |
