If everything still works (lights, heater/ac fan, radio, windows, door locks) but it doesn't crank at all meaning when you try to start it nothing happens. No noise, no clicking...nothing? It sounds to me like a fusable link between the battrey and the starter or a master fuse on the fuse panel and before the starter. Check the power wire at the starter and see if you have enough amps and volts to start it. If it doesn't the fusable link or master fuse is gone and you may have to get one from the dealer. I know on parking lot sweeper trucks, the GM Colorado truck have a 150 amp fuse after the fuse panel and before the starter wire thats for safety.
