Hello, and thank you for allowing me the opportunity to help you. If I am not online when you are, please allow me time to return. If the key will not go into the ignition then you need to try another key. If that keys works then replace the worn out key. If the other key does not work either then chances are that the key lock cylinder has failed. If the key will not insert then typically this is due to one of the tumblers failing in the cylinder. It will need to be replaced. Is this something that you plan on fixing yourself?
No, I am not able to do that. Can I call a locksmith, or will it have to be towed to the repair shop>
