This is a common problem with the new Chevy ignitions --- sometimes it is the ignition switch and sometimes it is the microchip inside the key itself. your best and cheapest way to get this fixed is to call a automotive locksmith and have them come out to your vehicle and determine if it is the key or the switch,,, either way it will only take 30 minutes to change out the ignition - or 10 minutes to re-program the key to the car. on the low end it will cost you 85 dollars -- on the high end it should not be more then 145 dollars ( this is with the new switch ).
