How do you replace the ignition cylinder on a 1997 toyota 4 runner

Here's what you need:
1) Drill
2) 5/32′ cobalt drill bit (use cobalt, it's for drilling hard metals and is necessary)
3) 10mm socket wrench
Here's what you do:
1) Remove panel underneath steering column (4 X 10mm bolts)
2) Remove plastic shield covering ignition (should just snap out)
3) On the underside of the ignition assembly, you'll see a small hole (~1/4′) about 2 inches back from where the key goes. Using the 5/32′ drill bit, drill up into the hole, trying to center the drill bit on the pin which is inside the hole. You can normally push this retaining pin in if the ignition is turned to the first position and slide the cylinder out.
4) When the pin is drilled out completely, the lock cylinder should be easy to pop out with a small flat head screwdriver pried just underneath where the key goes on the front of the ignition.
5) The new cylinder should slide right in (with the key inserted and turned to the first position - ACC)
Heres what it cost:
1) Ignition lock cylinder assembly from Toyota dealer ~ $115
2) 5/32′ cobalt drill bit ~$4
