Hi, I've just purchased 03 2.3 ghia, really happy with car in general but I got 2 keys witth the car 1 just standard key (which works fine, opens doors and starts car) the other a 2 button remote key last owner changed battery in the key but to no avail, the key itself opens the door and turns the ignition but car won't start with it!! I take it the transponder within the key doesn't work or the car doesn't recognise it? How do I fix that? I saw a reply somewhere that said get a key with remote off ebay but how do I know which one to get?? any help appreciated, thanks in advance.
