Hi, I got a fault message on my A6 indicating that the key battery needed replacing. I did that, and still get the same message. However it has now stopped synchronising with the car at all. I can unlock manually and get the car started by placing the key against the nominated spot on the dashboard
I've seen some videos online where earlier models can be resynchronised using the spare key in the ignition - but because my car has keyless ignition these other methods don't work.
Any thoughts on how to do this for a newer model?
Theres a chance the fault lies with the key itself of course...
