Power door lock actuators such as these work by using a small electric motor with a geared spindle to drive a plunger arm forward or backward. The direction of the plunger is determined by the polarity of the DC power supplied. By coupling the plunger arm to the existing rod within the car door which moves the door lock mechanism, the actuator can lock or unlock the door.



This motor driven actuator can be installed to add power door lock systems to most vehicles. Simple two wire hook-up for easy installation. Reverse polarity to push/pull. 0.75" travel. Includes mounting bracket, rod, and necessary hardware. 5-5/16" length.
