Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Allow the vehicle's electrical system to discharge for a few minutes before starting work.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard and/or in the engine compartment.
Remove the fuse related to the power locks (consult the owner’s manual for the correct fuse location).
Inspect the fuse; if it is blown, replace it with a fuse of the same amperage.

3. Test and Replace Key Fob Battery

Open the key fob using a small flat-head screwdriver.
Remove the old battery and replace it with a new one, ensuring correct polarity.
Reassemble the key fob and test its functionality.

4. Inspect Wiring and Connectors

Remove the door panel using a socket set and trim tools.
Check wiring harnesses for frayed wires or loose connections.
Clean any corroded connectors with electrical contact cleaner.
Secure any loose connectors and reassemble the door panel.

5. Test/Replace Door Lock Actuator

If the actuators are unresponsive, disconnect the door panel and access the actuator.
Apply direct battery voltage to the actuator terminals to test for operation.
If the actuator does not function, remove it and replace it with a new actuator.
