Replace a worn key cylinder and ignition switch in one step with the Standard Ignition Ignition Switch with Lock Cylinder, part number US-683, a direct-fit ignition switch for the 1998-1999 Nissan Altima. It combines the key-operated lock cylinder and the electrical switch in one unit. As the key turns through its positions, the switch sends power to the vehicle's ignition circuits.
