Switch removal:
From the front of the dash:
Remove the trim ring around the keyhole.
Drill out or dremel the two security bolts (once the tension is off of them, they come out easy).
Drill out the two small rivets. The plate around the switch in the dash should be loose now.
From under the dash:
Remove the wiring harness from the back of the switch (it just slides on the contacts, it's tight, get a thin screwdriver between the pieces and pry it loose).
Loosen the locknut right under the steering wheel where the steering lock connects with the steering column. Loosen the set screw that the locknut is holding. Don't completely remove it, but get it pretty loose.
The switch is now loose, and should come out. It takes a bit of maneuvering. Once it's out, you can remove the electrical portion from the mechanical portion with the two small flathead screws that hold them together.
Putting in is about 10 times harder than removing it
