ok thank you for your response I do have maybe three to four inches of travel in the steering wheel so does this mean that binding is not the issue?
If your steering wheel immobilizer is not the problem, it sounds like a problem with the lock itself. I only Know what i had to go through when I worked on my car. They stuffed a lot of things into a small space on a 107, so things may be totally different for you.
Can you turn the key at all? Could you have a worn key that is acting like the wrong key? How long since the lock has been lubricated? What type of lubricant was used?
Do NOT use WD40 as a lubricant. It is designed to displace water, protecting metal surfaces. It leaves a film that attracts dirt. The proper lube is dry graphite.
Someone may have used WD40, and you are suffering the consequences. A guy in the 107 thread ended up having to 'flush out' his lock cylinder by spraying a goodly amount of a solvent through it. It was messy and ugly, and involved putting plastic down to catch the solvent, but he was able to get the cylinder to turn enough that he could remove it. The cylinder has to be in a specific position for removal. He then was able to get a new one through the dealership for replacement.
That's the Bad scenario. The Worst scenario involves a locksmith. That one is not only messier and uglier, but expensive.
A couple more things to try,
