I've actually reprogrammed my A4 twice so I'm familiar with the general process, although the Vehicross' appears easier than the Audi's. I'm just concerned as the key FOB is entirely different than the one I had that works. Also, I'm not getting any response. I've held the green button in for 10-15 seconds or longer along with pressing one of the key FOB buttons. And before anyone asks, yes, the key is in the "on" position as well. Before I scrap the Ebay FOB and salvage the batteries, I wanted to know if anyone else had a similar sounding FOB, or did I just buy a FOB never meant for the Vehicross...
