Replacing the 811W46433-6018 Ignition Lock Cylinder is a moderately simple procedure that requires basic mechanical and electrical knowledge. This work should be performed by a qualified technician. Begin by disconnecting the battery negative terminal to prevent accidental short circuits.
Remove the steering column shroud to access the ignition lock cylinder. Insert the key and turn to the accessory position, then depress the retaining pin and slide the old cylinder out. Disconnect the ignition switch connector and withdraw the cylinder completely.
Insert the new 811W46433-6018 cylinder into the column housing, aligning the retaining pin with its slot. Push it fully into place until it clicks. Reconnect the ignition switch connector and refit the column shroud. Reconnect the battery and test all key positions: accessory, ignition, start and steering lock.
For ongoing maintenance, periodically lubricate the cylinder with a graphite-based lock lubricant and check that the key inserts and turns smoothly. If the cylinder becomes stiff, inspect the tumblers and ignition switch before replacing it again.
