3 Reasons Why Car Door Locked

Below we have considered the three most common reasons why your car door stays locked no matter how hard you try to open it:

A car door lock is damaged. One of the most common reasons you can't open your car door is the mechanical failure of the lock. Thus, door lock failures can occur due to rusty or deformed parts or stuck door latches. Another reason may be poor-quality or worn parts.

Worn car keys. Over time, your car keys might wear out and become malfunctioning. Thus, not only will you not be able to open the door of your car, but you will also damage the lock of your car door. This, in turn, can lead to more serious breakdowns.
A defective key fob. Also, the reason why you can't unlock your car door might be your key fob is malfunctioning or a battery is dead. Therefore, you can solve this problem by charging the key fob battery or contacting a professional locksmith for repairs.

How do you fix a car door locking mechanism

Replacing or repairing any part of your car requires special skills and knowledge. The same applies to repairing the lock mechanism of your car door. Therefore, you should not repair or replace any car door locking mechanism components yourself. It is best to entrust it to a professional locksmith who will be able to repair any breakdown qualitatively. If you’re still determined to repair your lock mechanism, then we have collected some tips for you.

First of all, check your key fob and battery. If you only need to charge or replace the battery in the key fob, then, of course, you can do it yourself. However, if the problem is more serious, it’s advisable to contact a locksmith company.

Check the electrical wiring of your car. Perhaps the problem can only be solved by replacing the wire or the blown fuse. Also, the cause of the breakdown may be a broken solenoid. In this case, it is better to contact a professional locksmith.
Lubricate the machine door locks. If one of the locks moves with difficulty or the key gets stuck in them during use, then try to lubricate the lock with a special lubricant.
If it’s cold outside, check whether the locks are not frozen. If you don't keep your car in the garage, your locks might freeze. To solve this problem, try to heat them.

How do I know if my car door lock actuator is broken

The door lock actuator is one of the most important parts of the locking mechanism of your car, which is responsible for locking and unlocking the doors. Thus, the car door lock actuator starts the gears in the electronic lock system, which opens and closes the car doors.

So how do you understand that your door lock actuator is not working properly? Well, randomly locking or unlocking your locks can indicate this. Extraneous sounds when opening or closing the lock can also indicate a breakdown. If there are no problems like this during use, pay attention to whether the car alarm does not work by chance. This could also indicate that the door lock actuator is broken.

As for the repair or replacement of the door lock actuator, everything is not so simple here. It is necessary to remove the inner lining of the door, disconnect the electrical wiring, remove the sealants and shields, and only then replace or repair the door lock actuator. Therefore, we recommend that you contact a professional locksmith company for help.

How do I reset my car door lock

After you've tried all the ways to fix your car door lock and it still won't work, then you can try resetting the lock system. But how to reset car door locks? There are several options. First, try disconnecting your car's battery for a few minutes. Thus, the locking mechanism should reset. If nothing happens, then you can quickly lock and unlock the lock several times using the switch on the car door. After that, the system should reset and work properly. If you still cannot reset the system, then it would be reasonable to contact a specialist.
