Is it possible to reprogram used keys? Here is one I found on ebay: http://cgi.ebay.co.uk/CITROEN-RELAY-REMOTE...p3286.m20.l1116 Also I found this new transponder key on ebay: http://cgi.ebay.co.uk/Citroen-Relay-Transp...p3286.m20.l1116 would a dealer be able to program that. I have the key code card with the electronic and mechanical code.
