It doesn't take long to pull the lock cylinder or remove the lock plate.

1. Disconnect the battery & remove the Steering Wheel. Remove the large nut holding the corrugated can on the steering column and use a puller with some long bolts to remove the can.
2. Remove the 3 screws holding the Turn signal Switch assembly and the 1 screw holding the lever to the switch.
3. Remove the snap ring holding the bearing to the shaft.
4. Remove the 3 screws holding the upper housing to the middle housing.
5. Disconnect the wiring under the column to give slack so you can move the upper housing out of the way.
6. Wiggle the Turns Signal switch up and out of the way. You can now pull a little slack out of the wiring you disconnected and freed in steps 5.
8. Wiggle or gently pry the upper column housing off of the middle column housing and pull it off the shaft. It's OK to let it hang on the Turn Signal Switch wiring if you need to but be gentle.
9. Remove the other snap ring on the shaft.
10. Pry up to remove the collar from the lock plate and then drive out the pin under the collar . Remove the lock plate.
11. Remove the two screws holding the column lock mechanism in place.
12. Under that plate you will see a small bolt. Remove it and the lock cylinder will come out. Later models have a small hole push a pin in it and pull out to remove the lock cylinder. Do not have keys in the lock cylinder.
13. Reassemble as needed.
