Since the ignition switch and ignition lock are 2 different components, I'm giving you both. First is the switch.
Removal & Installation
Without Air Bag
See Figures 1 and 2
The ignition switch is located on the lower part of the steering column.
Place the ignition in the LOCK position.
Fig. 1: Ignition/dimmer switch assembly
Remove any components necessary to access the switch.
Remove the two switch mounting screws.
Disconnect the switch from the rod.
Disconnect the wiring and remove the switch.
Fig. 2: Ignition switch rod positioning
On non-tilt columns:
Move the ignition switch slider to the OFF unlocked position (move the slider all the way down, then back two clicks). The remote rod hole in the ignition switch slider should now be centered.
Insert the remote rod in the ignition switch slider hole and install the ignition switch on the steering column. Tighten the attaching screws to 35 inch lbs. (4 Nm).
On tilt columns:
Insert the ignition key in the lock cylinder and turn the cylinder to the OFF unlocked position.
Move the ignition switch downward to eliminate any slack and tighten the attaching screws to 35 inch lbs. (4 Nm).
Install any components removed for switch access.
With Air Bag
See Figures 3 through 9
Disconnect the negative battery cable and disable the air bag system.
If equipped, remove the tilt lever.
Remove the upper and lower steering column covers with a suitable Torx® driver.
Using Snap-On® tamper-proof bit TTXR20BO or equivalent, remove the ignition switch screws.

Pull the ignition switch away from the column.
Release the 2 connector locks on the 7-terminal wiring connector and remove the connector from the ignition switch.
Fig. 4: Unplug the connector from the switch
Release the connector lock on the key-in-switch and halo light 4-terminal connector and remove the connector from the ignition switch.
Insert the key into the ignition lock and ensure it is in the LOCK position.
Using a small screwdriver, depress the key cylinder retaining pin so it is flush with the key cylinder surface.

Do not remove the cylinder at this time.
Turn the key to the LOCK position and remove the key.
Remove the ignition lock.
Install the electrical connectors to the switch. Ensure the switch locking tabs are fully seated in the wiring connectors.
Mount the ignition switch to the column. The dowel pin on the ignition switch assembly must engage with the column park-lock slider linkage. Ensure the ignition switch is in the lock position (flag is parallel with the ignition switch terminals).
Fig. 8: View of the switch from the column
Apply a dab of grease to the flag and pin. Position the park-lock link and slider to mid-travel. Position the ignition lock against the lock housing face. Ensure the pin is inserted into the park-lock link contour slot and tighten the retaining screw.
With the ignition lock and switch in the LOCK position, insert the lock into the switch assembly until it bottoms.

Assemble the column covers.
If equipped, install the tilt wheel lever.
Connect the negative battery cable.
From the right side of the vehicle (in case of accidental deployment), turn the ignition switch to the ON position.
Check for proper air bag warning light operation.
Here is the lock
See Figures 1, 2, 3 and 4
Remove the turn signal switch.
Insert the key in the lock cylinder and turn it to the ON position.

Remove the key warning buzzer switch and contacts AS AN ASSEMBLY using needle-nosed pliers, or a paper clip with a 90° bend.
Fig. 2: Lock cylinder retaining screw
Some steering columns may have a retaining screw holding the lock cylinder in the column. When servicing this type, simply remove the retaining screw and remove the lock cylinder.

Fig. 4: ... then pull out the lock cylinder from the steering column
With the ignition switch still in the ON position, insert a thin screwdriver into the slot adjacent to the switch attaching screw boss (right-hand slot). Depress the spring latch located at the bottom of the slot to release the lock cylinder.
Remove the lock cylinder.
To install the lock cylinder, turn the key to the LOCK position. Insert the lock cylinder in to the housing far enough to contact the drive tang. Force it inward and move the ignition switch actuator rod up and down to align the components. When the components align, the cylinder will move inward and the spring-loaded retainer will snap into place locking the lock cylinder in the housing.
If the lock cylinder is retained by a screw, tighten the screw to 40 inch lbs. (5 Nm).
Install the key warning buzzer switch.
Follow the ignition switch installation procedures to adjust the ignition switch.
Install the turn signal switch.
Please refer to the ignition switch removal and installation procedure.
