Solution
1. Preparation
  • Gather tools and parts: OBD-II scanner, multimeter, socket set, replacement fuses, and key fob battery.
  • Disconnect the vehicle's battery to ensure safety during electrical work.
2. Inspect and Replace Fuses
  • Locate the fuse box (usually under the dashboard or in the engine compartment).
  • Identify and remove the fuse related to the power door locks using a fuse puller.
  • Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.
3. Test and Replace Door Lock Switches
  • Remove the door panel using a socket set to access the door lock switches.
  • Disconnect the electrical connector from the switch.
  • Use a multimeter to check for continuity while pressing the switch.
  • Replace the switch if it does not show continuity.
4. Inspect Wiring and Connectors
  • Visually inspect wiring harnesses for frays, corrosion, or disconnections along the door frame.
  • Clean any corroded connectors and ensure they are securely connected.
  • Repair or replace damaged wiring as needed.
5. Replace Key Fob Battery (if applicable)
  • Open the key fob casing with a small flathead screwdriver.
  • Replace the old battery with a new one, ensuring correct polarity.
  • Reassemble the key fob and test its functionality.
