How to Fix a Car Door Lock, Identify the Causes

Car door locks are one of the proofs of technological advancement in the automotive field. Because door locks have become one of the safety features needed in modern times like today to prevent the risk of theft. Considering its vital function, car owners need to know how to repair car door locks to ensure security is always maintained. The following are the complete methods.

How to Repair Car Door Locks

There are several methods you need to know when you want to repair car door locks. The complete details are as follows.

1. Check and Repair the Connecting Wire

As previously explained, door locks are components that play a vital role in car security. Therefore, this component must always be maintained. However, over time, this component can experience damage.

To address a damaged car door lock, you can check the condition of the connecting wire that connects the door lock device to the car door. If the connecting wire is only cut at the end, you can stretch the connecting wire so that the bolt can be installed.

However, if the connecting wire is already broken, you need to replace it with a similar wire. You can do the wire replacement yourself or ask for help from a workshop.

2. Check the Fuse Section

If the connecting wire is still in good condition, but the door lock is still damaged, you can check the fuse section. Use a fuse tester to measure the voltage flowing through the fuse component.

If the voltage is not in accordance with the voltage required by the fuse, then it is certain that the fuse component has a problem. A damaged fuse cannot conduct electricity properly to the car door lock, so this component cannot function optimally.

3. Check the Module Section

If the connecting wire and fuse are in good condition, but the car door lock does not function, then you need to check the module section. To determine if the module is in good or damaged condition, simply press the lock button on the car remote.

If the module can lock and unlock according to the remote's instructions, it means the module is not damaged. However, if the module does not respond to the remote's instructions, then the car door lock also cannot function because the electrical flow cannot be delivered to the module or door lock.

4. Check the Actuator Motor Section

Lastly, you can check the components of the car's actuator motor. The actuator motor component functions as an automatic lock puller. When the actuator motor receives instructions to lock, a magnet will appear and pull the plunger so that the car door can be locked. Immediately replace the component if the actuator motor can no longer perform its function properly.

Causes of Car Door Lock Damage

There are several factors that cause car door locks to be damaged that you need to know. The complete causes are as follows.

1. Damaged Connecting Wire

The connecting wire is part of the door lock that functions to transmit electrical current to the actuator motor so that it can open and close the car door. If the wire is broken or damaged, the electrical current from the door lock to the actuator motor cannot be transmitted.

2. Damaged Fuse

A damaged fuse causes abnormal electrical voltage, thus disrupting the function of the door lock.

3. Damaged Module

A damaged module causes the door lock to be unable to receive electrical flow, so the door lock cannot function.

4. Actuator Motor

The actuator motor is a component that functions to pull the car door using electromagnetic fields. If this component is damaged, the car cannot be closed properly, thus it cannot be locked.

Thus is the review on how to repair damaged car door locks along with their causes. If the above problems occur in your car, immediately perform service at an official Daihatsu workshop.
