Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver set, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the battery to avoid any electrical shorts during repair.

2. Check Key Fob and Battery

Remove the key fob battery cover and replace the battery with a new one (CR2032).
Test the key fob again to see if it resolves the issue.

3. Inspect and Replace Fuses

Locate the fuse box under the dashboard and the engine compartment.
Identify the fuse for the power locks (refer to the owner's manual).
Remove the fuse using a fuse puller and check for continuity with a multimeter.
If blown, replace it with a fuse of the same amperage.

4. Test and Replace Door Lock Actuators

Remove the door panel using a screwdriver and trim tool.
Disconnect the wiring harness from the door lock actuator.
Apply direct battery voltage to the actuator to check for movement.
If the actuator does not respond, replace it with a new one.

5. Reassemble

Reconnect the wiring harness to the actuator and secure the door panel back in place.
Reconnect the vehicle's battery and ensure all connections are tight.
