Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, screwdriver, replacement battery for key fob.
Ensure you are in a well-lit area and the vehicle is parked safely.

2. Key Fob Battery Replacement

Using a small screwdriver, carefully pry open the key fob casing.
Remove the old battery, noting the orientation for the new battery.
Insert the new battery (usually CR2032) in the same orientation.
Snap the key fob casing back together securely.

3. Reprogram Key Fob (if necessary)

Enter the vehicle and close all doors.
Insert the key into the ignition and turn it to the "ON" position without starting the engine.
Within 5 seconds, turn the key back to the "OFF" position and remove it.
Press the "LOCK" button on the key fob for 1 second, then release it.
Turn the ignition switch back to "ON" and check if the doors lock/unlock with the remote.

4. Inspect Door Lock Actuators

Remove the door panel using a screwdriver and trim removal tool.
Inspect the wiring and connectors for any signs of wear or damage.
Test the door lock actuator by applying direct power from a battery to see if it functions.
Replace the actuator if it does not operate when powered directly.
