Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and electrical connectors.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Fuse

Locate the fuse box and identify the power lock fuse using the diagram in the owner's manual.
Remove the fuse with a fuse puller or pliers and inspect it for continuity.
Replace with a new fuse of the same amperage if the old fuse is blown.

3. Test Power Lock Switch

Reconnect the battery.
Use a multimeter to check for voltage at the power lock switch.
If there is no voltage, check wiring continuity from the switch to the fuse and the body control module (BCM).
If the switch is faulty, remove it and replace it with a new one.

4. Inspect Door Lock Actuators

Remove the door panel for access to the actuator.
Disconnect the actuator connector and test it with a multimeter.
If the actuator is faulty, remove it by unscrewing bolts and replace it with a new actuator, ensuring correct alignment.

5. Reassemble and Test

Reassemble the door panel and ensure all clips and screws are secured.
Reconnect the battery and test the power locks with the switch and remote.
