Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Key Fob Battery Replacement

Remove the battery cover from the key fob using a small flat-head screwdriver.
Replace the old battery with a new one (typically CR2032).
Reassemble the key fob and test the door locks.

3. Inspect Wiring and Connectors

Remove the interior door panel using a socket set to access the door lock actuator.
Examine the wiring harness for any frayed or damaged wires.
Clean and reconnect any corroded or loose connectors.

4. Test and Replace Door Lock Actuator

Using a multimeter, test the voltage at the door lock actuator when the lock/unlock button is pressed.
If the actuator does not receive power, trace the wiring back to the central locking module.
If the actuator is faulty (no movement or irregular readings), remove the actuator by unscrewing it from the door assembly and replace it with a new unit.

5. Reassemble and Finalize

Reattach the interior door panel, ensuring all clips and screws are secure.
Reconnect the vehicle's battery.
Test the functionality of the door locks with the key fob and door switches.
