To replace the battery in a VW remote, first carefully use a flat-head screwdriver to separate the two halves. Be gentle to avoid scratches. Remove the dead battery and insert a new one, making sure the positive side is facing down. Finally, reassemble the remote by pressing the halves back together until they snap securely.
Next, locate the small notch on the key fob. Insert a flathead screwdriver in this notch to gently pry open the fob. Be careful not to damage the casing. Once open, remove the old battery and note the orientation, as the new battery must be inserted the same way. Place the new battery into the slot, ensuring it fits snugly. After replacing the battery, align and press the key fob halves together until they snap back into place.
By following these steps, you can have your VW key fob fully operational in no time. If the remote still fails to work, further troubleshooting may be necessary. Next, we will explore common issues that can affect key fob functionality and their solutions.
