Abstract: A power actuator for a vehicle door locking mechanism includes a power operable actuator lever, a manual locking lever operated by a sill button or the like, and a transmission connector selectively coupling the power operable and manual levers so that they are reciprocated by a drive from the manual lever between locked and unlocked conditions. A superlocking motor is operable to rotate the transmission connector angularly about a longitudinal axis and disengage the connector from at least one of the levers to disable the manual lever and effect superlocking for maximum security.
