Question: Which key tool can I use for 8E transponders, from Audi A6L/Q7?
Answer: There are optional solutions. It can be done with some key programming tools.
VVDI2 commander and Zed-Full are two popular ones.
Noe that Xhorse VVDI2 is the best for it. Easy and fast!
But of course YMMV.
Here you go.
