Hi all, quick question. I have a Golf 8, 1 key works fine and the spare has been sat in a draw for a 2 - 3 years and does not work. I have put a fresh battery in it, tried putting the working battery from the main key in and also tried as the manual says and putting the fob in the cup holder (where the key antenna is). Nothing has worked, the light on the fob flashes but it will not lock, unlock or start the car.
VW say the key may need re-programming at a cost of £100. What I don't understand is how a key can lose its programming. I get that the battery was flat but surely the programming is not lost if the battery goes flat? Or does it?
