Schrader *IS* the OEM manufacturer... Chrysler and Schrader both independently confirmed this.... Unless they are both lying about it? Then I'm not sure lol.

And again, not sure what you mean by "programmed before you buy."? You can't just "program" them pop em in and use em... It doesn't work like that because there is no "learn" mode on the Crossfires... So yes, you *COULD* get em "pre-programmed" and put them in but you'd *STILL* have to take the card to the Chrysler dealership (One that has Crossfire programming capabilities at that because 9/10 dealers (at least here in Chicago) do NOT have these tools either).
