Do you have tilt or non tilt? The procedure for both is the same only different.
In either case, steering wheel, column lock plate and turn signal switch need to come off. On non tilt, remove 3 screws and the upper bearing housing. The push a tiny screw driver or paper clip in the hole in the lock housing to release the retaining tab, and pull the lock out.
It appears on tilt, insread of a hole there's a slot to stick a piece of flat stock to release the lock retainer. Got to be honest, the FSM is kind of vague on the lock removal procedure.
