The ignition systems on these cars are equipped with the PATS system; if the anti-theft system sees the key as not programed, then the vehicle will not start. Look to see if the Anti-Theft Light is illuminated. If it is, then try another spare key to see if that works. If it does, then the key that did not work will need to be replaced. If the car still does not start, then a Worldwide Diagnostic System tester needs to be used to see why the anti-theft will not accept the key. I recommend that you have a mechanic, such as one from YourMechanic, come by and diagnose the issue with your ignition switch, and recommend the best path to repair.
