Gary, once the locking pawl and clip are out of place, I know of no easy way to put in back together in the car. There is a rod on the side of the lock cylinder that has a flat on it. This engages and pushes the steering lock bolt into place. When you turn the key to 1st position, this little rod pulls the plastic pushrod back to the right and allows the lock bolt to release the wheel. This is soundind like you will need to replace the lock assy. Check here. I think they are available. You will ahve to lower the steering column to get the lock off the side of the column. I see no upside in trying to rebuild a lock cylinder. Get a new one.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
