Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, Phillips screwdriver, and replacement fuses if necessary.
Ensure the vehicle is in park, and disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Key Fob Battery

Remove the key fob cover using a flathead screwdriver.
Replace the old battery with a new one (CR2032 or as specified in the owner's manual).
Reassemble the key fob and test the locking mechanism.

3. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the fuse for the door locking system using the vehicle’s manual.
Remove the fuse using a fuse puller, and inspect it for continuity with a multimeter.
If blown, replace it with a new fuse of the same amperage rating.

4. Check Door Lock Actuators

Remove the door panel using a socket set and Phillips screwdriver.
Visually inspect the door lock actuators for any physical damage or disconnections.
If necessary, test the actuators with a multimeter to check for proper voltage and functionality.
Replace any faulty actuators by disconnecting the wiring harness and removing the mounting screws.

5. Reassemble and Test

Reattach the door panel ensuring all clips and screws are secured.
Reconnect the negative battery terminal.
Test the locking system with the key fob and manual switches to verify functionality.
