  3. Install the New Battery:

    • Insert the new CR2032 battery in the same orientation as the old one.
    • Ensure it is seated correctly and securely.

  4. Reassemble the Key Fob:

    • Replace and tighten the screws.
Step 2: Re-pair the Key Fob

  1. Enter the Vehicle:

Step 3: Perform a Software Update (if necessary)
  1. Check for Updates:
    • Navigate to 'Software' on the touchscreen.
    • If an update is available, connect to Wi-Fi and initiate the update.
Step 4: Test the Key Fob

  1. Test Lock/Unlock:

    • Press the lock and unlock buttons to check if the key fob is functioning correctly.
