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.

To install: 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.
