How do you remove the ignition lock cylinder from a 1994 Saturn sc2?

If it is like the '97 SC2, which it likely is:

Remove the plastic cover from around the steering column.

Turn the old ignition cylinder to ACC (I know what you are about to say... If you can turn the cylinder, why replace it. Unfortunately I can't answer that. I had to drill out the old lock to replace the one on my saturn. Please consult a locksmith before doing so. You don't want to drill into the wrong parts.)

With the old cylinder turned to ACC, there is a small button on the side (probably upper right towards the air vents) Push this button in and the old cylinder should pull out. Installation is reverse of removal (without the drilling...)
