I have a start issue, couple of guys with mercedes computers programers tried to find what the problems was, but they could not connected with car computer so we were lost on the problem cause. The only dealership that have the chrysler crossfire programer was 2 1/2 hours far away from were the car was and you know the bills they come with this guys, so I'm so happy now that I did step by step what the ilustration and photos remarked and boom the car started imediately, and so far everything is working propertly. We the Crossfire owners face a dificult situation, Chrysler are eliminating this programers or not investing in them anymore, Mercedes won't touch the car cause for them is not their brand even though it is a SLK 320 all over, so i don't know what we are going to do in the future unless we find a way to eliminate this safety key switch. again thanks for all your help.
