cts remote start
Call the dealer, it should be a simple flashing of the ecm and a new remote for the car. Its all controlled by the ecm now, next time you go to start your car turn the key all the way forwards to start it and then release the key immediately. It will start all on its own.
No, '09 CTS ECM not capable of that flasing. Even if you could it would cost an arm and a leg. Trade it in.
