I did some searching but couldn't come across anything definitive.

I'm looking for an extra keyfob for my b8.5. It has advanced key if that makes any difference.

Dealer wants about 400 including programming which seems crazy.

Is it possible to get a key from ebay and then get it programmed? Something like this

Or what about buying an S4 key from another car and reprogramming it?

Thanks
