Could be anything. Starter, key assembly, ecm, computer. Do you hear the starter? Do you hear the fuel pump kicking in before starting? Is the car struggling to start or no noise at all?
Is your Service Engine Soon light on? Check the codes. It's not unusual for these cars to blow both the crank and cam position sensors since they're identical twins and the stock ones are made of plastic, as are the replacements from Advance and Autozone. Getting them from the dealer or from NAPA is the way to go. If you don't hear the fuel pump priming when you turn the switch to ON and get no spark, or if the ECU fails to communicate with your OBD2 scanner then that's the ECU...
