You can automatically lock/unlock your car door with power door locks.
Power door locks consist of a control switch, locking door latch and an electric control solenoid. The control switch is energized by an electrical impulse which forces the control solenoid to push or pull the locking mechanism. Kits are available with instructions to convert your manual car door locks to power door locks.
Instructions
1. Identify a location to mount the module. You should mount the main module to a wiring harness or support strap or attach it to a firewall. Determine how the wires will run through the door boot and into the door. Remove the door panel to find a suitable spot to mount the actuator.
2. Mount the module using tie straps. This involves mounting the module to a stiff wiring harness under the dash or you can strap it to a dash support brace. Ensure the connection is secure and tight. Attach it to the firewall or kick panel area using the screw provided.
3. Plug the wiring harness into the mounted control module. The wires on the wiring harness are pre-wired and color coded to the wires on the actuator. Run the wires along their corresponding paths. The shorter side of the two five-wire groups will go into the driver's door and the longer set will run under the dash and into the passenger door. Secure the remainder of wires to the door.
4. Identify the position you have chosen for the actuator. It can mount directly to the door skin or you can mount the door strap to the door skin and then the actuator to the strap. The latter is the most popular method, as it allows you to make room for the door panel to be reinstalled.
5. Loop the metal rod through the hole in the actuator and align it with the door unlock/lock. Using a square metal clamp, connect the rod from the actuator to the rod on the door.
6. Ensure that the door panels fit properly and test your lock and latch assembly to verify that your installation is operable.
