Travinsky Posted February 21, 2018 Share Posted February 21, 2018 The spare key that came with my A4 Cabrio has never worked. I replaced the battery and the light comes on when I press it but it doesn't unlock the car, any suggestions? Quote Link to comment Share on other sites More sharing options...
Steve Q Posted February 22, 2018 Share Posted February 22, 2018 Hi Trevor, S the light is working but not unlocking the car, I'd say it needs reprogramming. cheers Steve Quote Link to comment Share on other sites More sharing options...
Travinsky Posted February 22, 2018 Author Share Posted February 22, 2018 Thanks Steve, pardon my ignorance but does that involve a trip to my Audi dealer? Quote Link to comment Share on other sites More sharing options...
