Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and replacement fuse/key fob battery if needed.
Ensure the vehicle is parked securely and the ignition is off.
Disconnect the vehicle battery by removing the negative terminal to prevent electrical shorts.

2. Replace Key Fob Battery

Identify the type of battery required for the key fob (typically CR2032).
Use a small flathead screwdriver to gently pry open the key fob casing.
Remove the old battery and insert the new battery with the correct polarity.
Reassemble the key fob and test the locking mechanism.

3. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power locks using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers. Inspect for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage rating (usually 10A or 15A).

4. Test Power Lock Switch

Remove the switch panel on the driver's door using a screwdriver.
Disconnect the wiring harness from the switch.
Use a multimeter to test continuity across the switch terminals while pressing the lock/unlock buttons.
If the switch is faulty, replace it with a new one.

5. Reconnect and Test

Reconnect the vehicle battery by attaching the negative terminal.
Test the power locks using both the key fob and interior switch to ensure functionality.
