I need to nurse my car home. The other day my wife went to Blockbuster. When she tried to start up to get home, something in the ignition failed. I have since removed the lock cylinder and found the disgruntled part. It is a silver shaft with two lobes on each side. It acts as a transmission from the key to the mechanism in the steering column.

How do I over-ride the steering lock mechanism, so that I can get my car home in my own garage???? Anybody have any photos?? Any help would be appreaciated. I imagine I can shove a screw driver down the hole to start it up. The auto-transmission lock is no problem.
