Hi All,

I just got a 2013 A4 and I only have one master key/FOB. I got a spare FOB from the dealer, is there any instructions that I can find to program the secondary FOB as I can't seem to find any online.

Most videos suggest using an external device, and I saw a post on eBay with some instructions - but i don't really trust it as most people are leaning to some device from Germany to China to program it.

Here is the link to the eBay instruction.

Thanks in advance and looking forward to getting the spare FOB working without going to the dealer.
