REMOVAL & INSTALLATION
Operational Lock Cylinders
See Figures 1 and 2
The following procedure pertains to vehicles that have functional lock cylinders and ignition keys.
- Disconnect the negative battery cable.
- For 1986-91 models, remove the trim shroud, then remove the electrical connector from the key warning switch.
- Turn the lock cylinder to the RUN position.
- Place a 1 / 8 in. (3mm) diameter pin or small drift punch in the hole located at 4 o'clock and 1 1 / 4 in. (32mm) from the outer edge of the lock cylinder housing. Depress the retaining pin and pull out the lock cylinder.
- On 1986-91 models, prior to installing the lock cylinder, lubricate the cylinder cavity, including the drive gear with lock lubricant D8AZ-19587-A or equivalent.
- Turn the lock cylinder to the RUN position, depress the retaining pin, and insert it into the lock cylinder housing. Make sure the cylinder is fully seated and aligned into the interlocking washer before turning the key to the OFF position. This action will permit the cylinder retaining pin to extend into the hole in the lock cylinder housing.
- Using the ignition key, rotate the lock cylinder to insure correct mechanical operation in all positions. Install the electrical connector onto the key warning switch.
- Connect the negative battery cable, then check for proper ignition functions and verify that the column is locked in the LOCK position. Install the trim shrouds.
When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 10 miles (16 km) or more to relearn the strategy.Non-Operational Lock Cylinders

The following procedure applies to vehicles where the ignition lock is inoperative and the lock cylinder cannot be rotated due to a lost or broken ignition key.
- Disconnect the negative battery cable.
- Remove the horn cover (or air bag module) and the steering wheel, as described earlier in this section.
- Remove the trim shrouds and the connector from the key warning switch.
For 1986-91 models, perform the following steps:
- Use a 1 / 8 in. (3mm) diameter drill to drill out the retaining pin, being careful not to drill any deeper than 1 / 2 in. (13mm).
- Place a chisel at the base of the ignition lock cylinder cap, then use a hammer to strike the chisel with sharp blows to break the cap away from the lock cylinder.
- For 1992-96 models, use a pair of locking pliers, or the equivalent, to twist the lock cylinder cap until it separates from the lock cylinder.
- Using a 3 / 8 in. (10mm) diameter drill, drill down the middle of the ignition lock key slot approximately 1 3 / 4 in. (45mm) until the lock cylinder breaks loose from the break-away base of the cylinder. Remove the lock cylinder and drill shavings from the lock cylinder housing.
- Remove the retainer, washer and ignition switch and actuator. Thoroughly clean all drill shavings and other foreign materials from the casting.
- Carefully inspect the lock cylinder housing for damage from the removal operation. If any damage is apparent, the housing must be replaced.
- Position the lock drive gear in the base of the lock cylinder housing in the same position as noted during the removal procedure. The position of the lock drive gear is correct if the last tooth on the drive gear meshes with the last tooth on the rack. Verify correct gear to rack alignment by inserting a flat bladed screwdriver in the recess of the gear and rotating it to the full counterclockwise position. After verification, rotate the drive gear back to the original removal position. Install the washer and retainer. Note that the flats in the recess of the drive gear align with the flats in the washer.
- Install the ignition lock cylinder as described in the previous procedure.
- Connect the key warning switch wire, then install the shroud.
- Install the steering wheel and horn cover or air bag module.
- Connect the negative battery cable.
- Check for proper ignition and accessory operation and verify that the column locks in the LOCK position.
When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 10 miles (16 km) or more to relearn the strategy.
