Ignition Key Programming
 

I purchase a 2013 from Hertz. Love the car. Great deal. I have my main ignition key and FOB (combo). I also have a second combo key/fob. The second combo key/fob works fine except the key doesn't turn over the ignition. It locks and unlocks the doors and the trunk...just doesn't turn over the ignition. I need assistance in learning how to program the key to start the car.
