Holden Door Locking Mechanism to Replace the Malfunctioning Door Lock Actuator

The electronic door lock actuator latches and locks/unlocks the door in a car with power locks. The actuator assembly of door locks in most current vehicles comprises a built-in latch mechanism as well as a switch sensor that detects whether the door is open or closed. Cables or mechanical linkages connect the door lock actuator to the inner and outer door knobs. As the vehicle ages, the actuator becomes rusty, and you may experience malfunctioning issues. This must be resolved immediately for your own safety.

Door Lock Actuator Failure

There could be a number of reasons that imply the need to replace the actuator of the door lock, and you should understand the Holden Door Locking Mechanism in case you have a Holden Car.

During lock/unlock operation, the worn-out and damaged actuator can produce a buzzing noise during lock/unlock operation. A failed actuator will cause the door lock not to work when all other door locks are working.

If the electric motor or mechanism within the door-lock actuator wears out, the door lock may lock or unlock slowly or intermittently. You may be able to lock the door of your car even in case of a faulty actuator; however, it will be a nightmare for you to unlock it.

The cable that links the actuator to the door handle is frequently integrated within the actuator assembly. If the cable breaks in this situation, the actuator component in the door lock may also need to be replaced. Take a look at the image of a damaged door lock cable.

The issue with the built-in switch that detects whether the door is open or closed might cause the “Door Ajar” warning light to remain illuminated even after the door is closed. The same issue might cause the anti-theft alarm to sound at random. It occasionally happens in rainy weather when water penetrates the actuator and shorts the switch within.

If the bolts that secure the door lock actuator become loose, the door will not lock correctly, so it is important to understand the door lock mechanism.

How the Door Lock Actuator is Tested

To diagnose, your mechanic may need to remove the door cover, inspect the door lock linkages, and measure the voltage at the door lock actuator using the wiring diagram. When the power lock button is pushed, the voltage is detected. In case you have sufficient voltage supply; however, the problem is in an actuator that causes malfunctioning or not working at all; the actuator is faulty and must be changed timely.

The second scenario could be no sign of voltage when the power lock switch is turned on; the electrical diagram must investigate the problem further. It might be a faulty main door lock switch, a faulty door wire harness, a faulty control module, or just a blown fuse. Also, see how to test a fuse.

How Can You Know Which Door Lock Actuator Sets Off the Alarm?

If you believe that one of the actuators in your Holden car is causing the alarm to sound in wet weather, the first thing you should do is inspect the weather strips above the door locks. A hole in the weather strip and the distance between the weather strip could be a possible cause. Water can get inside if the weather strip above the actuator does not seal correctly.

For example, you can check for a crack in the weather strip that allows water to enter the actuator below. Our industry experts have corrected the car’s random alarm that went off on wet days by sealing these holes in all the doors and lubricating the door locks and trunk/tailgate locks.

Check that all of the doors close smoothly and that the Door Ajar light turns off whenever a door is closed. If the light turns on and off intermittently while one of the doors is closed, the switch in that door is most likely to blame. If any of the door locks appear corroded, lubricate them with a suitable liquid lubricant.

If no evident malfunction is discovered, this issue can be evaluated at your local dealership. Using the dealership scan tool, the mechanic may identify which door or trunk or hood has recently activated the alarm. If the scan tool reveals that the same door generated repeated alarms, the door lock connection and actuator must be examined. Often, replacing the faulty actuator resolves the issue.

Replacement of the Holden Door Lock actuator

A door lock actuator replacement at a dealership may cost you $200-$350 in labour + $200-$270 in aftermarket OEM Parts. Although aftermarket components are less expensive ($180-$220), they are not accessible for all vehicles.

How simple is it to replace a door lock actuator as a do-it-yourself project? Parts Factory Australia would grade it a 6 out of 10, with ten being the most challenging. The door cover must be taken off. The entry inside the door is restricted, and you’d need a little torch to look inside. In some vehicles, the window regulator, as well as the window or the exterior door handle, may need to be removed, which might be difficult. The most challenging aspect is connecting all of the wires and connectors once the new door lock actuator is fitted.

Here comes the help from Parts Factory Australia with guided video tutorials available on YouTube. Our industry experts have made videos on how to replace car parts like a professional, and you can save thousands of bucks on car maintenance. The thing you need is the right tool set and confidence that you can get from our YouTube channel.
