Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner, replacement key fob battery, fuse puller.
Disconnect the negative battery terminal to prevent electrical shorts during repairs.

2. Inspect and Replace Key Fob Battery

Open the key fob using a small screwdriver.
Remove the old battery and replace it with a new CR2032 battery.
Reassemble the key fob and test the locking function.

3. Check and Replace Fuses

Locate the fuse box in the driver's side footwell.
Use a fuse puller to remove the door lock fuse.
Inspect the fuse for continuity using a multimeter.
If blown, replace it with the same amperage fuse (typically 10A).
Reattach the fuse and check if the doors lock.

4. Inspect Wiring and Connectors

Remove the door panel using a screwdriver to detach screws and clips.
Inspect the wiring harness for signs of wear, fraying, or corrosion.
If damage is found, repair or replace the wiring as needed.
Reconnect the harness and reassemble the door panel.

5. Test and Replace Door Lock Actuators

Disconnect the actuator from the wiring harness.
Use a multimeter to check for voltage when activating the switch.
If there is no voltage, the problem may lie in the switch or wiring; if voltage is present, the actuator may need replacement.
To replace, unscrew the actuator from the door mechanism and install a new one.
Reconnect the actuator to the wiring harness and test its function.

6. Reassemble and Test

Reattach the door panel and secure all clips and screws.
Reconnect the negative battery terminal.
Test the locking mechanism using both the key fob and the door switch.
