- Carefully pry off any clips and screws holding the panel in place.
Disconnect the wiring harness from the power lock actuator.
Remove the screws securing the actuator to the door and take out the old actuator.
Install the new power lock actuator in reverse order.
Reconnect the wiring harness and reassemble the door panel.

4. Replace Power Lock Switch (if necessary)

Locate the power lock switch in the driver’s door panel.
Use the trim removal tool to gently pry off the switch panel.
Disconnect the wiring harness from the switch.
Install the new switch by connecting the harness and securing it back in place.
