Obtain two self-shear screws from your Nissan dealer, needed to reinstall the steering lock. Remove the steering wheel, then take off the top and bottom steering column covers, which are attached by two retaining screws each. Next, remove the instrument panel combination switches and the trim panel from the cluster panel by taking out the four retaining screws. The steering lock/ignition switch assembly is secured to the steering shaft with two self-shear screws that must be carefully drilled out, requiring precise drilling. Disconnect the ignition switch electrical connector. For installation, align the mating surface of the steering lock with the hole in the steering column tube, loosely install the two self-shear screws, and after checking the operation of the lock with the key, tighten the screws until the tops snap off. Finally, install the instrument cluster panel trim piece, the instrument panel combination switches, the top and bottom steering column trim pieces, and then the steering wheel.
