[jetfixer]

Total pain since to change the lock cylinder/key assembly you have to be able to turn the key to remove the lock cylinder!

Removal (See Autozone.com for installation instructions)

1. Disable the SIR system. Refer to the Chassis Electrical Section.
2. Remove the knee bolster.
3. Remove the steering column trim covers from the steering column.
4. Disconnect the steering column electrical connectors.
5. Remove the wire harness assembly from the steering column and the wire harness strap.
6. Slide the 2 connectors of the turn signal and multifunction switch assembly out of the bulkhead connector.
7. Remove the key alarm connector (1) from the lock module assembly (2) in the following way:
   
   1. Rotate the key alarm connector (1) 90 degrees.
   2. Pull the key alarm connector (1) out of the lock module assembly (2)
8. Remove the passkey connector from the lock module assembly (2).
9. Remove the connector (2) from the electric park lock (1), for vehicles equipped with floor shifters.
10. Remove the ignition switch from the lock module using the J 42759.

Did you try turning the wheel back and forth? Some times the wheel lock jams the ignition.
