Check the Wire

A bad control module could be the reason behind a non-working door lock button inside the car. These modules are responsible for the electric locking and unlocking mechanisms. They connect to the actual latch and handle through a series of rods that allow them to move between up and down. The system will stop working properly when they wear out. This is a problem that happens in older cars.

There are other problems that can cause the door to lock, and then become stuck in a locked state, like grime or dirt that has accumulated on the lock mechanism, a collision or a door handle that is jammed. A simple lubrication can fix the issue. A penetrating catalyst or WD-40 can be purchased at most home improvement centers, auto supply stores, or on the internet, and used to lubricate car door locks via the keyhole.

If you're unable to unlock the door using the key or button located inside the vehicle it's an excellent idea to inspect the fuses and wiring to see if any issues could be occurring. If the wiring is in good condition it's likely to be with the solenoids for power locks and actuators.

The process for taking off the handle and interior panel varies from car to vehicle, but the concept is the same. Generally speaking, you'll have to find and remove all the fasteners that keep the handle plate or panel in place and then gently pull them up without breaking the pieces off. You'll then be able to access the door latch and the lock actuator to check what's happening. Once you've gotten the panel out, you can usually access the latch that is locked by placing a screwdriver between the legs of the door latch, and pushing it upwards until it reaches its final position that is unlocked. Then you can shut the door to verify that the latch has been reset.

Check the Actuator

Like all electrical devices, the door lock actuator could begin to malfunction in time. It can be caused by a number of reasons, including corrosion caused by exposure to water or other contaminants. The actuator can also be damaged or misaligned because of excessive force or mechanical stress.

One of the most frequent signs that the door lock actuator is starting to fail is when you're unable to unlock the doors even if you use the key fob or manually trigger the switch inside the vehicle. This could be a serious problem, as it means that someone is able to lock the car without the right keys.

The first step in evaluating the condition of the door lock actuator is to check whether it's receiving power from the vehicle's central locking system or power windows control module. Then, you can test the function of the actuator with a multimeter, looking for any unusual or irregular behavior. Additionally you can inspect the actuator for indications of wear or damage and ensure that the linkage isn't obstructed or tied up.

It is important to remember that the actuator isn't repairable and should be replaced in the event that it fails. It is possible to do this with the help of a professional, but you should know that you will probably have to take off the door panel for accessing the actuator.

It's a good idea, before you attempt any tests on the actuator of the door lock, to put on safety glasses and to consult the owner's manual of your vehicle to find out about the recommended safety precautions. It's also a good idea to ensure that you're working on a solid surface and have access to a suitable socket.

To test the actuator you must locate the latch inside the front door as well as the gap or hole it is supposed to be able to latch into. After you've done that then, place a key or pen into the gap. Then flick/push the object towards the door in an upwards motion. If the door latch moves, then it's likely that the actuator is operating properly and the issue is in the remote or key fob.
