Replace a worn, sticking key cylinder and a tired ignition switch in one step with the Standard Ignition Ignition Switch With Lock Cylinder, part number US-633. This Standard Ignition switch pairs the lock cylinder and the electrical switch in a single unit. It is a direct-fit replacement for the 1998-2002 Subaru Forester. See the Buyer's Guide tab for engine details.

  • Global OE ignition maker: Standard Ignition manufactures original equipment ignition products worldwide and keeps quality control in-house, from componentry through the finished product.
  • Copper alloy conductors: Used for superior electrical conductivity with low resistive losses.
  • 100% tested: Every unit is checked to verify both mechanical and electrical switching performance.
  • Built for proper fit and function: The switch line uses high-grade materials in a robust design made for the stringent demands of today's service professional.

What it does: The lock cylinder accepts your key and turns the switch through its positions. The switch then routes power to the ignition and accessory circuits and signals the starter to crank.

Signs this part may need replacing:

  • A key that sticks or is hard to turn
  • Intermittent no-crank or no-start
  • Dash lights or accessories cutting out when the key is moved
  • Stalling while driving

Because other faults can cause the same symptoms, diagnose the cause first. If the original cylinder or switch is at fault, US-633 replaces both.
