Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdriver.
Ensure the vehicle is parked safely and the ignition is off.

2. Key Fob Battery Replacement

Remove the key fob cover using a small screwdriver.
Replace the old battery with a new CR2032 battery, ensuring correct polarity.
Reassemble the key fob and test the locking function.

3. Inspect and Test 12V Battery

Use a multimeter to check the voltage of the 12V battery; it should read around 12.6V when fully charged.
If the battery voltage is low, jump-start or replace the battery as necessary.

4. Check Door Lock Relay and Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller to remove the door lock fuse; inspect it for continuity with a multimeter and replace if blown.
Access the door lock relay; test it by swapping it with a similar relay in the fuse box to see if the locks respond.

5. Software Update

Connect the vehicle to Wi-Fi and check for any available software updates through the vehicle's touchscreen interface.
Follow the prompts to complete the update, which may resolve any electronic control issues.

6. Wiring Inspection

Remove the door panel using a socket set and screwdriver to access the door lock actuator.
Visually inspect wiring for any fraying or disconnections.
Use a multimeter to test for continuity in the wiring harness leading to the actuator.
