Hi Footlocker04,
Sorry to hear you had this issue and fortunately you were able to get the key out of the ignition. If you continue to have this problem, I would suggest speaking with your dealership to have them check the key and the ignition cylinder. Because I don't have access to dealer pricing on repairs, you would have to check with your local dealership.
Please keep me posted on how it goes.
