How To Fix A Car Door Lock


Is It The Car’s Actuator?

It’s true that car power locks are convenient to remotely access cars with the push of a button to lock and unlock the doors. But, like all electronics, mechanisms can fail. Cars with power door locks or central locking contain a device called an actuator, which responds to electric signals for keyless entries. Each door lock has its own actuator. When mounted behind the car doors panels, actuators are mounted vertically so they can move the metal hook to the locks up to open and down to lock. If the actuator isn’t defective or blown a fuse, even though it may sound daunting, there are ways to inspect a jammed lock and fix a car door lock without taking your car to a mechanic or dealership. When the actuator wears out, it can cost a fortune to replace it depending on the car’s make and model, so why not try to do-it-yourself.

Check The Remote Battery

Like any remote, the key also has a battery that requires replacement when dead. Use the key to manually open and lock all the car doors before ruling on anything. If it’s just an individual or two locks that won’t open, you know it hasn’t blown a fuse. And now you know how to fix a car door lock by replacing remote batteries.

Use Spray Lubricant To Fix A Car Door Lock

Extreme weather conditions can also cause a car door lock to get stuck. Try spraying the inside of a jammed car door lock or locks with WD-40 - or any multi-purpose spray using the thin tube. You can also use P-7 - a multi-functional penetrating oil for electrical use. What these do are essentially lubricate moving parts that are stuck while displacing moisture and removing grime, tar, grease and rust. Penetrating oils offer a corrosion protection and leave behind a non- conductive film. They are safe on metal, plastics and rubber. After spraying, let it sit for about 10-12 minutes and then try again.



How To Fix A Car Door Lock By Removing The Door Handle Panel Instead

Many videos found on the internet on how to fix a car door lock, suggests removing the panel of the door to repair malfunctioning parts. While that is an option, it is also time consuming and might just not be required in solving the problem of fixing a car door lock. A more viable approach would be to use a screw driver and unscrew the door handle panel only which will enable you to see the lock mechanism with the actuator. Spray them with WD-40 or P-7 because that should loosen it up. After a few minutes, using pliers, try moving the lever up and down which connects to a riveting disc to push up the door lock. It would be helpful to repeat the action a few times just to loosen it up so the movement gets smooth before you try to use your key or the power door lock again.
