2006 Ion 3, radio not working after alternator\dead battery
 

My alternator went out on me while driving to college the other day.
I had my car towed to a local mechanic, where they replaced the alternator and the battery.
After getting the car back, there is no power to my radio and the key is stuck in the ACCESSORY position.
Please help, I'm in college and I need my tunes!
I need to get this key out of the ignition as well.
I heard there is an "Anti-Theft" mode that the car might be in, as it thinks it's being stolen.

Take the car back to the mechanic.
