Replace the Key Fob Battery

Follow these steps to replace the weak battery in your Opel Mokka key fob:

1. Obtain a fresh CR2032 or CR2025 coin cell battery as specified in your vehicle owner's manual.
2. Use a small flat-head screwdriver to carefully pry open the key fob casing at the designated seam.
3. Remove the exhausted battery from the internal housing, noting the positive (+) and negative (-) orientation.
4. Insert the new battery, ensuring it is clean, free of oils, and firmly seated in the correct polarity.
5. Snap the fob casing halves back together until they are flush and fully secured.
6. Verify the fix by attempting to start the vehicle normally without using the emergency induction procedure; the engine should start immediately upon pressing the Start/Stop button.
