Solution

1. Preparation

Gather necessary tools and replacement parts.
Disconnect the vehicle's battery to prevent any electrical short circuits.
Tools Required: Socket set, multimeter, OBD-II scanner, wiring diagram.

2. Key Fob Battery Replacement

Sub-step 1: Open the key fob using a flat-head screwdriver to avoid damage.
Sub-step 2: Remove the old battery and replace it with a new CR2032 battery, ensuring correct polarity.
Sub-step 3: Reassemble the key fob and test if the locks respond.

3. Fuse Check and Replacement

Sub-step 1: Locate the fuse box, typically found under the dashboard or in the engine compartment.
Sub-step 2: Refer to the owner's manual to identify the specific fuse for the power locks.
Sub-step 3: Use a fuse puller or pliers to remove the fuse and check if it is blown.
Sub-step 4: If blown, replace with a new fuse of the same amperage (typically 10-15A).

4. Inspect and Repair Wiring

Sub-step 1: Remove the door panels to access the wiring harnesses for the door lock actuators.
Sub-step 2: Visually inspect the wiring for any signs of wear, fraying, or corrosion.
Sub-step 3: Repair or replace any damaged wiring as needed, ensuring secure connections.
