This is the steering column from below with the plastic bottom cover removed. In the center of the pic, between the wire and the shadow of the wire, you can see the hole that accesses the pin in the cylinder surround that holds the cylinder in place. This is the pin that must be pushed up to remove the lock cylinder.
In the previous post, you can see the plastic cover. I have a phillips screwdriver going through the hole in the plastic cover that reveals the hole in the cylinder surround.
