Door lock actuator is a small component that makes a big difference. It is one of the most important components in your car’s door mechanism. The door locks fail when you hear a loud click and nothing happens with the doors. This is often due to a faulty relay which can be replaced with one from another vehicle in the mean time to make sure it works. However, if that doesn’t solve your problem then there may be something wrong with the actual actuating mechanism itself which will require replacement as well as diagnosis of why it failed in the first place.

If you hear a loud click but nothing happens with the doors, this is often due to a faulty relay which can be replaced with one from another vehicle in the mean time to make sure it works.
How Door Lock Actuator Mechanism Works for Holden Commodore Cars?
A door lock actuator is a motor that operates the locking mechanism of the car door. The actuator is connected to the lock cylinder and it is powered by a 12V battery. When the key is turned, it sends a signal to the actuator which makes it turn in one direction or another. This causes different components inside the door handle mechanism. The most common purpose of this movement is to open or close your car’s doors, but some models also have locks that can be opened from outside if needed (for example during an emergency situation).

You can determine if the relay is faulty by testing it with a multimeter. You can also test if the actuator is working, as this could be an issue.
A faulty relay can cause your door locks to stop working, so it’s best to replace it with one from another car in the mean time until you get hold of an original replacement.
What is a Door Lock Actuator and How to fix it?
Door lock actuators are a common component of any vehicle. They’re responsible for activating the locking mechanism on your car doors, so you can keep them secure when you’re driving.
There are two different types of door lock actuators: interior and exterior. The interior type is found inside your vehicle’s cabin, while the exterior type operates out in the open on each side of your car’s bodywork.
If either one of these components becomes faulty or defective, it could cause all sorts of problems with opening and closing doors correctly—including locking yourself out! That’s why it’s important that you understand how this system works before trying to fix anything yourself…
You can fix your Holden door lock actuator very easily.
In order to fix your Holden door lock actuator, you will need to know the car and have the right tools. This may seem obvious, but it is true that some people do not know how to operate a car and do not even have a license. If this is your case, fix your car by hiring someone else!
Be careful of what you are doing and make sure that when you are working on something important in the engine of your Holden, make sure that nothing accidentally breaks or falls out onto the ground while doing so.
Disconnect the batteries.
To disconnect the batteries, you need to first disconnect the negative battery terminal. Then, you can disconnect the positive battery terminal. If you try to go in reverse order, the car will not start and if you try to connect them in reverse order, they may become damaged.
Open the door.
- Open the door.
- Remove the door panel. You’ll need to locate and unscrew three screws on each side of the door panel in order to fully remove it. You’ll also want to disconnect two electrical connectors that are on either side of your lock actuator, as well as one connector that is connected directly to it (it’s easiest if you just push in both sides). If there are any clips holding down your door panel, they should come off with little effort.
- Locate your lock actuator by following these steps:
- Find where you think it should be located (typically right next to where your keyhole would be).
- Take a look at how many bolts stick out from this area and measure them all—they should be evenly spaced apart from one another so that they fit into corresponding holes throughout other parts of your car, including ones inside its doors like handles or latches (see picture below).
- This will tell us what type of Holden cars yours belongs too! Now we can move onto finding compatible replacements for this component!
Determine where the problem is.
You will need to check your door lock actuator, door lock relay, and the door lock switch. The next step is to check the door lock motor.
Remove the door panel.
To begin, you’ll need to remove the door panel. To do this, carefully pry off the door panel from the door with a flathead screwdriver or other similar tool. If there’s no visible damage to your vehicle and you don’t have a replacement part in hand yet, it may be easier to remove just part of the door panel instead of taking it all off.
Next up: Remove the actuator from your vehicle (this is where having a diagram handy will come in handy). The actuator is connected to different parts of your Holden car by metal clips that slip onto grooves on each side of its body and into holes drilled into them—it will only fit one way so there’s no need for guesswork here! When these clips are removed, disconnect all wires leading up into your Holden car’s doors by pulling gently at either end until they’re free; these wires should be labeled according to their function so look closely once they’re out before discarding them completely if necessary (and remember how many there were originally!).
Unscrewing the lock actuator.
Unscrewing the lock actuator is a fairly simple process. First, you’ll need to remove the door panel on your Holden. This can be done by removing several screws and loosening one or two clips that hold the panel in place. Then, you’ll want to unscrew the lock actuator from surrounding components (like hinges) using your Phillips screwdriver and make sure it’s disconnected from any electrical connections as well.
Once this is done, you’re ready to reassemble your car door!
Disconnect the lock actuator from surrounding components
- Disconnect the lock actuator from surrounding components.
- Remove the door panel and then the interior handle assembly.
- Unscrew the lock actuator from the lock cylinder with a 13mm wrench or socket, depending on your vehicle. To remove it completely, you’ll need to also unscrew two bolts that connect it to either side of your vehicle.
Install replacement units.
Once you have located your actuators, remove the old units. It’s a good idea to label them so that you know which one was for the exterior door lock and which was for the interior lock. Then, install your new ones in their place and make sure that they are connected properly. For example, if a wire harness comes with your actuator set then this should be connected to it. Also, make sure that any other components of your replacement unit are attached to each other according to instructions included with it.
Finally, test all locks by opening/closing them several times before moving on with further steps of installing new door lock actuators into Holden cars!
Replacing your car’s door locks is a fairly easy job which anyone can perform in less than an hour using simple tools.
Replacing your car’s door locks is a fairly easy job which anyone can perform in less than an hour using simple tools. The process does require some care, however, as you don’t want to damage the interior of your Holden. With that in mind, here’s what you’ll need to do:
- Use a screwdriver to carefully pry up the rubber door lock trim surrounding the latch assembly and remove it from around the edge of the door panel. Then use a wrench (or adjustable wrench) to loosen and remove all three bolts holding down each latch assembly. This may require some force if they’ve been on there for years like mine were! Once they are all off, gently pull out each old assembly and install new ones by lining up tabs on them with holes on either side of where they attach onto metal rods behind panels’ edges (where you removed screws earlier). Be careful not to damage plastic covers over these rods when removing/installing new parts as well! If needed, replace any damaged covers with appropriate replacements available for purchase at any auto parts store or online via websites such Parts Factory or stores like ebay.
Conclusion
The door locks fail when you hear a loud click and nothing happens with the doors. This is often due to a faulty relay which can be replaced with one from another vehicle in the mean time to make sure it works.
