Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner, wire connectors, electrical tape.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box (usually found under the dashboard or in the engine bay).
Identify and remove the fuse related to the power locks.
Use a multimeter to check continuity of the fuse.
Replace with a new fuse of the same amperage if found faulty.

3. Repair or Replace the Power Lock Switch

Remove the panel covering the power lock switch using a screwdriver.
Disconnect the wiring harness from the switch.
Test the switch using a multimeter; if it does not show continuity when pressed, replace the switch with a new one.
Reconnect the wiring harness and reassemble the panel.

4. Test Key Fob

Open the key fob and replace the battery with a new CR2032 battery.
Reprogram the key fob according to the owner’s manual instructions.
Test the key fob to ensure it sends signals to lock/unlock the doors.

5. Check and Replace Door Lock Actuators

Remove the door panel to access the door lock actuator.
Disconnect the actuator wiring harness.
Test the actuator by connecting it directly to a power source; if it does not respond, replace the actuator.
Install the new actuator and reconnect the wiring harness before reassembling the door panel.
