Still Not Working?

If your Volkswagen key FOB isn’t working after switching out the battery, then the key FOB itself could be malfunctioning. There is also a chance that it could be a mechanical issue. There may be ways to fix this yourself, but the easiest way to make sure it’s fixed and done correctly is to have a professional do it for you. Electrical components can be very finnicky to repair without proper know-how. In some instances, they can also be dangerous.
