ABSTRACT:
An apparatus and method are described, for converting vehicle door locks that can be only manually operated, into door locks that can be either electrically or manually opened and closed. The door lock originally has a key-operated lock device with a key cylinder projecting to the outside and with a lock member that can be moved to prevent rotation of a latch (22, FIG. 5) to its open position to enable opening of the door. The original door lock device is removed and a power pack (60) is installed, which includes a mechanism (64) that can engage the door latch, with the mechanism being operated by either an electrically energized action motor (70) or a key operated lock device (40A). The key operated lock device on the power pack has a cylinder (84) that mounts in the same position as the key cylinder of the original lock device that was removed.
