Signs Your VW Key Fob Battery Needs Replacing
Several signs indicate your VW key fob battery is nearing its end. Recognizing these early can save you the headache of a non-responsive key fob. Reduced operating range is often the first sign. You might find yourself having to stand closer to your car to lock or unlock it. Another tell-tale sign is a weak or intermittent signal. The car might not respond to the key fob on the first try, requiring multiple button presses. Dimming key fob lights or a complete absence of light can also point to a dying battery. Finally, if your car only starts when the key fob is very close to the ignition, the battery is likely the culprit.
