A legit service would be to replace lost keys for a few bucks rather than the $100's a dealer charges for one key.
It's easy to get a replacement key, but you need VW to program it. Hopefully that process becomes public.
My model (2013 Polo Vivo Blueline) came with one electronic key/remote, and one mechanical key. So I can buy another electronic key, but I can't use the remote without VW programming it.
you'll just need the contents of the 95040 eeprom on your ECU - you can dump it from the OBD2 port with various tools
