Ignition Switch - REMOVAL & INSTALLATION
(see Figure 1)

1. Disconnect the negative battery cable.
2. Remove the lower column trim panel, then remove the steering column-to-instrument panel fasteners and carefully lower the column for access to the switch.
3. Place the ignition switch in the OFF-LOCK position.
   

If the lock cylinder was removed on vehicles through 1991, the actuating rod should be pulled up until it stops, then moved down one detent; the switch is now in the Lock position.

Fig. 1: Adjusting the ignition switch

1. Remove the ignition switch-to-steering column retainers, then remove the assembly.
   

To install:

1. Before installing the ignition switch, place it in the OFF-LOCK position, then make sure that the lock cylinder and actuating rod are in the Locked position (1st detent from the top or 1st detent to the right of far left detent travel).

Most replacement switches are pinned in the OFF-LOCK position for installation purposes. If so, the pin MUST be removed after installation or damage may occur.

1. Install the activating rod into the ignition switch and assemble the switch onto the steering column. Once the switch is properly positioned, tighten the ignition switch-to-steering column retainers to 35 inch lbs. (4.0 Nm).
   

When installing the ignition switch, use only the specified screws since over length screws could impair the collapsibility of the column.

1. Raise the column into position and secure, then install any necessary trim plates.
2. Make sure the ignition is OFF , then connect the negative battery cable.

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

Steps to remove and replace the lock cylinder To Remove the Lock Cylinder 1: Remove the cover UPPER/LOWER) from the steering column(usually 2 phillips screws in lower cover, directly behind the steering wheel. 2: Turn the key to the run position (the position before start). 3: Using a small diameter object (paper clip) slide the wire into the hole located underneath the ignition switch on the underside of the column. While pushing up on the pin in the hole, turn the key and pull outward. The tumbler should release and come out. 4: To replace, turn the key in the new cylinder to run. 6: Place the cylinder in the column where the old one came out. 7: Turn the key to the off position and the cylinder is now locked in place.

BMW ignition lock replacing.

According to manual no special tools needed. here procedure!

1. Ignition elec switch. Disconnect battery. 2. remove trimpanel from lower leftside of instrument panel. remove screw retaining lower steering column and remove cove. 3. remove slotted screws on both side of switch. 4. relase tabs and remove switch from elec harnass and remove sealer.. note: before mating new ignition elec switch check that switch is in correct position. seal screws again.
2. Ignition lock cylinder replacing. 1. insert master key and turn 60 deg to radio position. 2. inset piece of stiff wire into opening in lock cylinder and pull cylinder out. (Note early models up to 10/95 turn lock cylinder back 12 deg to release)

It is not necessary to have the dealer do this, think of the cash! Though it does require patience and time. The pin you are supposed to push in goes into a slot when you have it in run position, since you cannot turn it to run you have to make a slot for the pin to go into, with a drill. Be very careful as you only have a 1/4" of play before you break a washer behind the cylinder. Once you have drilled out the key far enough to the pin hole you can take a nail set and tap the pin up, you can tell when the pin clears the housing, then it just takes wiggle, patience and tinkering to get the cylinder to slide out, keep the green washer and the metal slot washer. Metal slot washer goes in first with green plastic washer ontop of that with lock cylinder in last. You can play around with the new lock cylinder and washer before insertion to determin correct direction.

Here are official directions with inoperable lock cylinder. They say drill out retaining pin but it just spun in circles for me - I looked at new cylinder and saw how it worked. retaining pin needs a place to go.

You need to remove the shroud so you can see the whole lock assembly.Once this is removed you should see a little silver retainer pin. While pushing in on the pin, rotate the lock with the key in it, until you feel the pin drop in. At this point you can start to pull the lock out. You may need a torx driver to unscrew some of the bolts, but there are no special tools needed to actually remove the lock assembly , besides a working key.
