Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Key Fob Battery

Open the key fob casing using a small flathead screwdriver.
Remove the old battery and replace it with a new one (typically CR2032).
Reassemble the key fob and test its functionality.

3. Inspect and Replace Fuse

Locate the fuse box, refer to the owner’s manual for the exact location of the power lock fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reinstall the fuse box cover.

4. Door Panel Removal

Use a trim removal tool to carefully pry off the door panel.
Remove screws securing the panel (if any) and gently detach clips holding it in place.
Lift the panel upwards to remove it from the door.

5. Inspect Lock Actuator and Wiring

Check the door lock actuator for any signs of physical damage.
Using a multimeter, check for voltage at the actuator connector when the lock switch is activated.
If voltage is present but the actuator does not operate, replace the door lock actuator.

6. Reassemble and Test

Reattach the door panel by aligning it and pressing it down until it clicks into place.
Reconnect the battery and test the power locks using the key fob and interior switch.
