Keith;

I don't know what you mean by "serious encouragement", but I hope you didn't beat the hell out of it, which would do needless and unnecessary damage to the rest of the IGN sw assy. Generally, locks are intended to withstand such insults!

You need to turn the lock cylinder (LC) to the IGN ON position...I suggest working the key back and forth in the cylinder as you apply rotational force with a small screwdriver...patience helps...once it turns ONE CLICK, into the IGN ON position, (and only then, are you able to) push the release button and withdraw the LC. The bezel will come along with the LC. You will then also be able to remove the key fragment and get a new key cut with the pattern it still has.
