Fix your Door Lock Actuator is Compulsory

Your vehicle’s power Door Lock Actuator system is one of the most convenient features. It allows you to lock and unlock your vehicle with a button. This can become especially useful when you have children who need to get out of the car quickly, have an injured leg, or when it’s cold outside, and you want to keep your hands warm while unlocking the door instead of fumbling around with a key. However, even with all these benefits, it’s easy for something to go wrong with this system. One common defect involves actuators—small electric motors responsible for moving locks into position when they sense power is supplied through their wires.

The Door Lock Actuator is one of the most convenient features of a power door lock system.

When you press the button on your key fob or the driver’s door switch, the lock actuator uses rotary motion to unlock and lock the doors. This is a small electric motor connected to your car’s locking mechanism. The lock actuator is one of the most convenient features of a power door lock system that allows you to open and close your car’s doors without having to use a key or insert an ignition switch.

Door Lock ActuatorThe problem may get caused by lousy ground, broken wire, or a faulty actuator.

Door Lock Actuator is essential in the proper functioning of a power door lock system.

Actuators are the motors that make your power door locks work. They enable you to lock and unlock your doors, and they’re a common cause of problems with your power door locks.

Most modern cars use actuators to control their power door locks. They’re reliable, but they tend to wear out over time. If you have trouble with your car’s power door locks, it may be time for a new one!

Replacing an actuator is easy and cheap enough that most people can do it themselves without difficulty—especially if you follow our instructions carefully!

The Door Lock Actuator’s rotary motion facilitates the locking and unlocking process.

The actuator is a cylindrical device located on the door lock switch. The actuator gets connected to the door lock switch, which allows it to rotate when activated by you.

The actuator rotates until it reaches a particular position. Once it comes to that position, your car will unlock or lock automatically. The most common problem with a Door Lock Actuator is when it fails to make the door lock or unlock.

The most common problem with a door lock actuator is when it fails to make the door lock or unlock. For example, if you’re in your car and want to get out, your door won’t open because of faulty wiring from the motor. This can become very frustrating, especially if it’s at night and there’s nobody around to help you get out of your car.

Another issue is an intermittent switch between locking and unlocking functions.

  • If the actuator gets broken, it will not function properly. If the actuator is clean, it may work poorly.
  • If the actuator is misaligned, you may experience problems with locking or unlocking your door.
  • If the actuator doesn’t connect to the door lock or housing (if present), it won’t work as intended and could be causing problems for you.

An inconvenient but not uncommon problem with door lock actuators is when they get stuck in one position. Occasionally, the Door Lock Actuator will get stuck in one position. This can happen for any of the following reasons:

  • The door lock actuator is jammed or broken and cannot move. In this case, you will need to replace your old actuator with a new one.
  • The motor is malfunctioning and is constantly running even when it shouldn’t be (e.g., when the car ignition is off). You may need to adjust your motor’s speed by changing a few settings on your dashboard controls. If this doesn’t work out for you, check out our article on fixing a faulty motor that won’t stop running!

You can purchase aftermarket units or try fixing the existing team in materials.

  • The most common problem with a Door Lock Actuator is when it fails to make the door lock or unlock. This can cause by dirt getting into the locking mechanism and jamming it up. If this happens, check all your wiring connections to ensure they are secure. Then spray some WD-40 cleaner into all moving parts of the actuator (make sure not to get any on any electrical connectors). You may also need to remove dirt inside the actuator before everything works smoothly again.

It would help if you fixed your damaged power door locks as soon as possible.

If you’re reading this, your power door locks are likely broken. You may be able to fix them yourself, but if not, you can pay for a mechanic or buy a new car.

If you want to fix it yourself:

  • You’ll need to get in the trunk of your car and disconnect the battery (or turn off the main power) so that there’s no electrical current running through any part of your car while working on it.
  • Next, look at each component of your door lock system and carefully figure out which one needs replacement. Your symptoms will tell you what kind of problem exists with each element. If only one side does get jammed up or not work at all. Then chances are something went wrong with that side’s actuator motor or solenoid coil unit. If both sides are jammed up but work when pressed manually on their respective actuators’ cylinders. Then something probably went wrong with either one’s wiring harness leading from its separate central control unit (CCU) box into its cylinder housing assembly.


Fixing your power Door Lock Actuator is a relatively simple task that you can perform in less than an hour. If the repair doesn’t solve your problem, you may need to replace the actuator with a new one. In any case, it’s best to have this done by someone who knows what they’re doing because, otherwise, additional damage could cause when replacing or repairing the unit.
