What is Rear Lift Gate Locking Mechanism?

Rear lift gate locks are a feature that has nearly become a standard feature on many newer vehicles. They make the task of locking the vehicle's doors as simple as pressing a button on the key fob or inside of the vehicle. The door locks are electronically controlled, and as is the case with many other automotive electrical circuits, they will run their power through a relay. The door lock relay is the relay responsible for sending power to the door lock actuators so that they can lock and unlock the vehicle. When the relay fails or has issues, it can cause problems with the operation of the door locks.
