My 2006 Crossfire base coupe V6 will not start. Recently installed camshaft and Crankshift sensors. Doing fine and driving good, Driving from grocery shopping taking my daughter home it would not start. Tried and tried. No go. I notice its done this about 4 times in a two year period. Usually it will start. But now NOTHING. My mechanic checked it out and says it is the Skim Module Security System. Do I need to take it to the Dealer or can a mechanic fix it? I've heard horror stories about this that not even Dealers could remedy. HELP! Pie
