Standard Ignition Ignition Lock Cylinder and Switch P/N:US-171

Get your key turning and your ignition circuits switching again with the Standard Ignition Ignition Lock Cylinder and Switch (US-171). It drops in as a direct-fit replacement for the 1987-1989 Mitsubishi Precis, combining the key-operated lock cylinder and the electrical ignition switch in one serviceable unit.

This combination part handles two jobs: the lock cylinder holds the tumblers your key rotates, while the ignition switch routes power through the off, accessory, run, and start positions as the cylinder turns.

  • Integrated design: pairs the ignition lock cylinder with the ignition switch for a single replacement.
  • Key-operated cylinder: houses the tumblers the vehicle key engages to rotate the assembly.
  • Ignition switching: controls the electrical positions that feed the starter and accessory circuits.

Signs this part may need replacing include a key that is hard to insert or turn, worn tumblers, or intermittent power to the ignition circuits. If a failed lock cylinder or switch is the cause, this assembly replaces it — diagnose the underlying fault before installing.

Frequently Asked Questions

What vehicles does the US-171 fit?

It is a direct-fit replacement for the 1987-1989 Mitsubishi Precis. Check the Buyer's Guide tab to confirm fitment for your vehicle.

What does this part do?

It combines the key-operated ignition lock cylinder and the ignition switch, so the key rotates the cylinder while the switch routes power through the off, accessory, run, and start positions.

Why is my key hard to turn or won't turn?

Worn tumblers in the lock cylinder can make a key hard to insert or rotate. If a failed cylinder is the cause, this assembly replaces it; diagnose the fault first.

Does replacing this fix a no-start?

A no-start has several possible causes. If a failed ignition switch is not sending power to the starter circuit, replacing this assembly addresses that; verify the cause before ordering.

What interchange numbers does it cross-reference?

It cross-references CS157, KS6683, 8190021100, 8190021190, 8190621120, 90021100, 90621120, and LC14920.
