Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box and identify the fuse for the power locks based on the owner’s manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Replace Key Fob Battery (if necessary)

Open the key fob using a small screwdriver or trim removal tool.
Remove the old battery, noting the orientation.
Insert the new battery in the same orientation.
Reassemble the key fob.

4. Inspect Wiring and Connectors

Remove the door panel using a trim removal tool and socket set.
Visually inspect the wiring and connectors leading to the door lock actuator for damage.
Repair or replace any damaged wires or connectors.
