1. Key Fob Battery Replacement

Sub-steps:
- Open the key fob using a small flathead screwdriver.
- Remove the old battery and replace it with a new battery of the same type (typically CR2032).
- Reassemble the key fob and test it.

2. Fuse Inspection and Replacement

Sub-steps:
- Locate the fuse box (usually under the dashboard or in the engine compartment).
- Identify the fuse related to the door locks (refer to the owner's manual for exact location).
- Remove the fuse using a fuse puller and inspect it for continuity.
- Replace the blown fuse with one of the same amperage (usually 10A or 15A).
- Close the fuse box and test the remote functionality again.

3. Door Lock Actuator Inspection

Sub-steps:
- Remove the door panel by unscrewing screws and unclipping the panel from the door frame.
- Access the door lock actuator by detaching any connectors and screws holding it in place.
- Test the actuator with a multimeter to ensure it is functioning properly (check for voltage when activated).
- If faulty, replace the actuator with a new one, reconnect the wiring, and reassemble the door panel.
