What is a Central Door Lock Relay?

Although power door locks were once a rare feature in vehicles, they are now standard equipment on most vehicles. The lock serves two purposes: to provide safety for your vehicle and passengers as well as making it easier to open and shut the doors. It is as easy as pressing a button on the key fob, or inside your car to do this. Relay power powers all electronic door locks.

The central door lock relay controls power supply to door lock actuators. All doors can be locked and unlocked by this relay. The button is pressed to complete a circuit. Once the button has been pressed, the lock actuator will activate the lock mechanism to the desired position. Door locks may not work properly if the relay is defective or fails.

 

What are the symptoms of a Central Door Lock Relay Failure

An errant door lock relay can cause some problems. These are the most common symptoms of a malfunction:

 

Intermittent Operation Electric Door Locks

Intermittent door locks operation is one of many symptoms that indicate a defective door lock relay. Door locks can malfunction and open or lock intermittently if there are any wiring problems or internal faults. It can be very frustrating for drivers trying to lock and unlock their vehicles.

 

Electric door locks not working

A common problem is the inability to get power doors locked. If the relay is damaged, the power supply to all doors will be cut, which can cause the doors to stop working. Vehicles with lock cylinders inside their doors can be opened manually by using the key. Vehicles without lock cylinders cannot be locked or unlocked until the electrical problem has been resolved.
