Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and replacement fuses or components if needed.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard on the driver’s side or in the engine compartment.
Remove the cover and identify the fuse for the power locks (refer to the diagram on the fuse box cover).
Use a fuse puller or pliers to remove the fuse and inspect it for damage.
If blown, replace it with a new fuse of the same amperage (typically 10A or 15A, check your owner's manual for specifics).

3. Test and Replace Power Lock Switch

Remove the panel covering the power lock switch using a flathead screwdriver.
Disconnect the switch connector and use a multimeter to test for continuity.
If no continuity is detected, replace the power lock switch with a new unit.
Reconnect the switch and reassemble the panel.

4. Check the Wiring and Connectors

Inspect the wiring harness leading to the door lock actuators for any signs of wear or damage.
Disconnect the connectors and clean any corrosion with electrical cleaner.
Reconnect all wiring securely and ensure no wires are pinched or exposed.

5. Key Fob Battery Replacement

Open the key fob using a small flathead screwdriver or coin.
Remove the old battery and replace it with a new one (typically a CR2032 or similar).
Reassemble the key fob and test the locking/unlocking function.
