Honda Accord Door Lock Actuator

How to Spot Problems on Your Honda Accord Door Lock Actuator

Locking and unlocking the doors of your Honda Accord is a crucial aspect in operating the car. These are affected by your door lock actuator, the motor inside your door panel that moves the door latch to open or close the door. When your door lock actuator is bad, your car is open for anyone's easy access. More so, you may experience the frustration from difficulty in unlocking the door. With this, before things get worse, you should know when your door lock actuator is running its final miles.

Buzzing sounds

Your door lock actuator has two rubber stoppers inside. These stoppers secure the position of the motor inside the actuator. There are times when one of these rubber components slides out of its place. When this happens, the motor also moves slightly out of its position. This causes the buzzing sounds when operating your door lock actuator. To fix this, open the actuator and secure the position of the rubber stops with quick-drying silicone.

One door lock does not work with the use of the central switch

If one of your door locks do not work when using the central switch, there may be an issue with the wiring of your door lock actuator. The actuator may not be getting enough voltage to make it move the door latch. This may be caused by a poor relay. You can check your relay and look for possible short circuits or small damage. You may also try replacing the relay.

Sluggish operations

You would know when your lock is getting slow or sluggish. This can be annoying because your lock takes some time before finally opening or closing. This problem is caused by a burned door lock actuator which tends to slow down before finally giving in. This part burns because of corrosion and dirt inside your door panel. With this, you should replace your burned actuator and regularly keep the new one from dirt and dust.

Door locks and unlocks on its own

This is a rare symptom that can be a little creepy at the same time. This is caused by a bad actuator wiring. What you can do is check the wires. They may be touching ground somewhere, causing intermittent activations of the actuator. If these continue, the actuator may die due to excess work.

  • How to Make Sure Your Honda Accord Door Lock Actuator Works Well 27 February 2013

    The door lock actuator functions by controlling the lock of your door. With this, it is a very important security component that keeps the interior of your car from easy access. More so, it allows you to electronically control all four of your door locks. Indeed, the door lock actuator offers safety and comfort. However, it causes the opposite once it is damaged. That's the main reason why you have to take good care of this part. Following are some ways you can do so.


    Lubricate its connections from time to time.


    Your Honda Accord door lock actuator works electronically and manually. With this, you need to make sure its mechanical parts are working smoothly together. You can do this by often lubricating these parts. Your actuator contains gears that are mated together, which function better with proper lubrication. Teflon- or silicon-based lubricants are enough to keep these gears working efficiently.


    Clean your door lock actuator regularly.


    Corrosion and dust inside the door panel can damage the motor of your actuator. These small particles burn when they make contact with the actuator's motor. If this happens, your motor may burn as well. The motor is the most crucial part in your actuator because it produces the movement that opens and closes the latch of your door. If it's already burned, your door lock actuator needs to be replaced.


    Often check the wirings of your Honda Accord door lock actuator.


    Your actuator is powered by electricity, so you should ensure the delivery of ample voltage for it to work efficiently. Make it a habit to look into the fuse, relay, and wires. You have to make sure they are grounded properly. Common issues like intermittent actuator operations are caused by electrical problems.


    Be careful when installing your new door lock actuator.


    Needless to say, much care is required in installing a new auto part. This includes your door lock actuator. When installing this part, you should avoid damaging its surrounding parts such as the outer handle rod and cylinder rod. These metal rods may bend while you are installing your new door lock actuator. If they bend, the actuator would need to work harder, reducing its service life.
