When you put the key in the ignition, it goes further and doesn't want to start. I've told a few people and they have said it could either be the ignition switch or the starter. The lights still work, so I don't think it is the battery.
Yes, the ignition switch is bad and would need to be replaced. I recommend you have a qualified mechanic check it for you since working on or around the air bags require proper knowledge of the system.
