Do Keyless-GO keys require programming?
I'm in need of an extra Keyless-GO key and am planning on ordering one from the dealer. I've heard from different dealers different things, most say that Keyless-GO keys need to be programmed and charge another 1-2 hours of labor on top of the key; some dealers say that the key should be pre-programmed directly from mercedes and doesn't require any additional programming. My question is who's telling the truth? Can anyone answer this?
