Ken: Normally, when you are in "1" position the key is inserted. Now you insert the wire tool and that releases the lock because your wire tool depresses the latch. Now the lock comes out when you pull on the key. It comes out together with the collar. For the purpose of this exercise the escutchion plate has been removed. If the escutchion plate has not been removed it will come out too because it sits around the small diameter of the collar. Yes, I know, you don't have a key handle. What you have now in your hand is the lock and the collar. The collar is still around the lock. But because you can manipulate the lock, like turn it, you can remove the collar by pulling it off. You have to pull the key first, because the collar opening is smaller than the handle of the key. Now you have the naked lock in your hand. It looks to me, that it may not be a repairable part, but I did not take it apart. To assemble the stuff: Remember, the lock is still in the "1" position: You insert the lock cylinder into the location in the dash: There is a 1/4 inch keyway that indexes the lock cylinder. The key is not in the lock at this time. Then you insert the collar. Then you install the escutchion plate. Everything is in place now, the lock is still in the "1" position. Now you can insert the key and it works. That's how I remember it. I hope, I remember right.
