Solution

1. Preparation

Gather tools: Socket set, screwdriver set, multimeter, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Replace the Key Fob Battery

Remove the key fob cover using a small screwdriver.
Take out the old battery and replace it with a new one (usually CR2032).
Reassemble the key fob and test the locks.

3. Check and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the fuse for the power locks (refer to the fuse diagram).
Remove the fuse and inspect it; replace with a new fuse of the same amperage if blown.

4. Inspect Door Lock Switch and Wiring

Remove the door panel using a screwdriver and pry tool.
Check the power lock switch for any visible damage or loose connections.
Using the multimeter, test the switch for continuity when pressed.
If defective, replace the switch.

5. Test and Replace Power Lock Motor (if necessary)

With the door panel removed, locate the power lock actuator.
Use a multimeter to check for voltage at the actuator connector while pressing the lock switch.
If voltage is present but the actuator does not operate, replace the actuator.
Reverse the disassembly steps to reassemble the door panel.

6. Reconnect Battery and Test System

Reconnect the negative battery terminal.
Test the power locks using both the key fob and the interior switch.
