Hi, pmercury. Could you please help me. I have a 2004 SL600 with keyless go. All works fine. With 2 keys. I wanted to have a card for keyless go to keep in my wallet so I don't have to carry keys. I have bought card ordered to my chassis from Mercedes but doesnt work. Keyless go doesn't work neither does the button on card to open doors. Is there any way I can get this card to work on my car? Many thanks
