Hi, to let you know that the cheverolet problems with the ignition switch in the dash, the one that wont let it crank and the security system says it is shutting it down, I have an '03 Monte Carlo that was doing the same thing. You need to replace the ignition switch HOUSING. That is what the wiring harness plugs into on the back. It will cost around $100, more or less depending on where you live and where you go. It took me forever to figure this out and I hope that it helps a lot of people out there save time and money trying to fix the problem.
