Well I got the key Friday and it works ,I can lock and unlock the doors with the buttons , when I hit unlock two times the windows and sun roof will open and on lock the second time I press lock the windows and sun roof will close.

But my Keyless Go Don't work when I try it , Question Is What Is The trick or setting to get KEYLESS GO to work On My 05 S500 W220
