I only have 1 key with my car and would like 2 

1st question if I buy a 3 fob key off eBay that's never been programmed can I do this with vcds after I've had it cut or can it been done with the old one in ignition and new one in the door any help be grate 

Alarm part can be done with a working key and the new one. Imobiliser part to start the car is a tad more involved. Best find a VW key and locks bloke to sort it out.
