What to know about the Door Lock Switch:
Door lock buttons are electrical rocker buttons that are used to lock and unlock car doors. When you activate the switch, it sends a signal to the door lock relay to activate the door lock actuator inside the door. Due to regular use, the switches and electrical currents running through them eventually fail, necessitating replacement.
Facts to Note:
Many modern vehicles have a complete lock assembly which needs to be changed if the switch dies.
How to Fix:
Test the operation of the electric door locks.
Test the fuse for that circuit.
Test the relay.
Change the defective door lock switch.
Test for proper operation of electric door locks.
Door lock systems are not a part of regular upkeep, but it’s not rare for the switches to die. If you notice that your vehicle is not locking and unlocking when you press the corresponding buttons, it’s time to schedule an inspection.
Common symptoms indicating you may need to change the Door Lock Switch:

Importance of this service:
The door lock switch acts as a remote for the door lock actuator, which is responsible for locking and unlocking your vehicle’s doors. When you press the lock or unlock button, the switch triggers the actuator, and the door is locked or unlocked. When the lock switch dies, the actuator has no way of being activated, and your door locks will stop working.
