Check the Key
Over time, the tumblers inside your car door lock may become blocked by dirt and rust. This can prevent the lock from working when you use the key fob, or turn the ignition key. This can cause the mechanism of the lock to become jammed. If this happens, you'll have to take off the door handle, and then open the lock mechanism to free it. It's an easy DIY project that can be done at home.
There are many reasons why your door latch could be stuck. It could be due to a physical obstruction within the latch mechanism or an electrical issue with your key fob. Someone might have knocked the latch to it's locked position even though the door was still open.
If the problem is with your key, try taking it out and in the lock several times to see whether the tumblers move freely. This will usually reset the lock.
You can also try a lock de-icer to melt the ice and allow you to open the door. If you're still having issues, spray some multi-purpose lubricant on the door lock mechanism. Be sure to turn off the lock before you do this. Otherwise, you may damage the latch mechanism.
When the lock is well-lubricated, you should be able to open it with your door handle. If you cannot, there may be a problem with the latch mechanism and you will require replacing it.
You can fix a latch that is stuck by using an screwdriver to manually push the latch to the unlocked position. To do this begin by pulling the interior, then the handle on the outside of the car. Then, use a screwdriver to put pressure against the left side of the latch, so that it can be pushed upward to the unlocked position. Repeat the process on the left leg of the latch to reset it. Close the door once the latch has been unlocked to test the latch.
Check the Battery
Car door locks work by sending electronic signals from a key fob to the solenoid in each door. It then converts those signals into a mechanical action, in this instance turning a rod of steel that is then able to latch the door. It can be a hassle if your car's doors don't lock or unlock via the key fob or from either inside or outside. Fortunately, you can often fix the issue without having to take your car to mechanic.
The door lock mechanism could be blocked. To determine this, open your door and inspect the latch mechanism. It should be apparent that it has "open" jaws on the other side designed to grab the anchor inside the door jamb and turn into a closed position to connect the latch to the anchor. If the latch is shut and doesn't rotate to the right position, it will not be able to connect with the anchor and close the door.
It is possible to fix this by applying WD-40 or some other oil lubricant to the inside of the door. Then you can use a screwdriver to move the latch into an open position so that you can work on rotating it back into its proper position. It's an ideal idea to have a friend or family member help in this process as it can be very difficult to do alone without damaging something.
After you've lubricated your latch mechanism, it's important that you don't attempt to force the key in. You could break the key in the lock if you attempt this.
If you are still having problems locking or unlocking your car using the key fob and you've tried the steps above then it is recommended to contact a professional technician who will provide more advanced diagnostics and repairs. They'll be able to determine the cause of the problem and recommend the best solution for your vehicle and you.
Check the Wiring
If the door lock button on the inside of your vehicle isn't working, it could be a malfunctioning control module. These modules are responsible for the electric locking and unlocking mechanisms. They are connected to the handle and latch via a series rods that allow them to move upwards and downwards. When they start to wear out the system stops working correctly. This is a problem that happens in older vehicles.
There are other problems that could cause the door to lock and then get stuck in a locked position like grime or dirt that has accumulated on the lock mechanism, a collision or a jammed door handle. A simple lubrication can fix the issue. You can purchase WD-40 or a penetrating catalyst in hardware stores, auto supply shops or even online. You can use it to lubricate your car door locks via the keyhole.
If you are unable to unlock the door using the button or key on the inside of the vehicle it's an excellent idea to inspect the wiring and fuses for any issues that could be occurring. If car locks repair is fine it's likely to be with one of the power lock solenoids or actuators.
A professional locksmith can solve any problems that arise with the locks on your car's door. They can also help you install any new features like smart keys that will make your car more comfortable in the future.
The procedure for removing the interior panel and handle varies from car to vehicle, but the concept is the same. You'll generally need to find and take off all fasteners holding the handle plate or the panel in place, and then slowly remove the panels without breaking them. You'll then be able to access the door latch and lock actuator to check what's going on. After removing the panel, you can access the locked latch with the screwdriver. Set it between the legs of door latch and then push it upwards to its final unlocked position. Then you can close the door to confirm whether the latch has been reset.
Check the Actuator
As with all electrical devices, the door lock actuator may start to malfunction as time passes. It could be due to a variety of causes including corrosion caused by exposure to water or other contaminants. The actuator can also be damaged or misaligned due to excessive pressure or mechanical stress.
If you're unable to open the doors with the key fob, or even manually activating the switch in the vehicle, this is a typical sign that the actuator is failing. This could be a serious problem, as it means that someone is able to lock the car without the correct keys.
The first step to evaluate the condition of the door lock actuator is to check whether it is receiving power from the vehicle's central locking system or the power windows control module. Then you can test the function of the actuator with a multimeter, noting any odd or erratic behavior. You can also examine the actuator to check for evidence of wear and tear and ensure that the linkage isn't obstructed.
It is important to remember that the actuator is not repairable and must be replaced in the event that it goes bad. You can do this with the help of a professional, but you should know that you'll probably require the removal of the door panel for accessing the actuator.
Before attempting to perform any tests on the door lock actuator, it's always a good idea to put on your safety glasses and refer to the manual for the vehicle owner's guideline for the recommended safety precautions. Also, make sure you're working on a level surface and have a socket readily available.
To test the actuator, you'll need to locate the latch inside the door and locate the gap or hole it's supposed to get caught in. Once you've done this you can insert a key or pen into the gap and flick/push it towards the door in a semi-upward direction. If the door's latch moves then the actuator is likely to be working correctly and the issue lies with the remote or key fob.
