Nissan 48750-0M010 Ignition Switch

New shear-bolts must be used when refitting the lock assembly. To remove the lock assembly, first disconnect the battery negative terminal. Lower the steering column to its lowest point and remove the steering column shrouds. Disconnect the two wiring connectors from the left-hand side of the steering column. For models with an intelligent key system, disconnect the wiring connector from the top of the ignition switch. Next, disconnect the wiring connector to the transponder ring around the ignition switch, undo the retaining screw, and withdraw the transponder ring from around the switch. To remove the lock assembly, drill out and remove the two shear-bolts from the top of the steering column, then withdraw the two sections of the lock casting from the steering column, noting that the lock assembly cannot be removed from the casting. Refitting is a reversal of removal, but when refitting the lock assembly, use two new shear-bolts and tighten the bolts until the heads break off.
