Get your key turning and your ignition system responding again with the Standard Ignition Ignition Lock Cylinder and Switch (US-861). It installs as a direct-fit replacement on the 2004-2007 Nissan Frontier, combining the key cylinder and the electrical ignition switch in a single service assembly.
The lock cylinder accepts and holds the vehicle key and rotates through its ignition positions, while the integrated switch routes power to the accessory, run, and start circuits as the key is turned. Together they let you unlock the steering and hand off the crank signal that starts the engine.
- Combined assembly: pairs the key lock cylinder with the ignition switch so both wear items are replaced together.
- Key-position control: turns through the off, accessory, run, and start positions to signal the correct circuits.
- Direct fit: designed to replace the original unit on the listed application.
Signs this part may need replacing include a key that is hard to turn or sticks, a no-crank condition, or intermittent power to the accessory and run circuits. If a worn lock cylinder or failed ignition switch is the cause, this assembly replaces it; diagnose the fault before ordering.
