Door lock switch

A door lock switch is a device that is used to lock and unlock your car doors from inside the car’s cabin. It is basically found in the door pull or armrest area. The main lock switch can found in the driver’s door panel that permits the driver to lock or unlock all the doors with just a flick of the switch. They have become a standard for modern vehicles that come with a power door locking system.

How Door lock switch work?

It is a rocker, which turns back and forth while your car door is locked and unlocked. After the switch has been turned in a single direction, the power is allowed to enter the door lock so that the door locking mechanism is triggered. Two solenoid terminals receive electricity from the lock switch to lock the door. In order to activate the voltage, the duality is reversed by the switch before the solenoid is supplied.


Symptoms of a bad door lock switch

When a car door lock switch goes bad, it can show a few symptoms. If you see the following symptoms then it’s time to replace that part.

The switch can no longer operate because the power required to trigger the door lock mechanism is not supplied. It is a huge problem to have a door which cannot be locked, which could expose you and your passengers, especially on the road. When the vehicle is driving, you can unintentionally open your car door. To fix this issue, have someone check and repair your switch if it's defective. Make sure the other parts, such as the door lock actuator or wires, are also tested so they don't trigger a problem.
