Solution
1. Preparation
  • Gather tools: screwdriver set, multimeter, and a replacement key fob battery (CR2032).
  • Ensure the vehicle is in "Park" mode and turn it off.
2. Check Key Fob Battery
  • Remove the key fob casing using a small screwdriver.
  • Replace the old battery with a new CR2032 battery ensuring the correct polarity.
  • Reassemble the key fob and test its functionality.
3. Update Vehicle Software
  • Access the settings on the touchscreen.
  • Go to “Software” and check for updates.
  • If an update is available, follow the prompts to install the latest software version.
4. Inspect Door Lock Actuators
  • Remove the interior door panel using a screwdriver to access the lock actuator.
  • Check the wiring harness connected to the actuator for any loose connections or damage.
  • Use a multimeter to test the actuator for proper voltage when the lock button is pressed.
  • If the actuator is faulty, replace it with a new unit.
5. Reset Vehicle Systems
  • Perform a hard reset by holding down both scroll wheels on the steering wheel until the screen turns off and reboots.
  • Wait for the system to restart, then test the power locks again.
