Keep your shifter locked until you're ready to move with the Standard Ignition Shift Interlock Actuator (P/N SIA100). It drops in as a direct-fit replacement for the 2007-2014 Ford Expedition, 2009-2010 Ford F-150, 2010 Ford Lobo, and 2010 Lincoln Mark LT — see the Buyer's Guide tab for the full engine-level list. As the electromechanical component of the brake-transmission shift interlock, it controls the release that lets the lever move out of Park, working with the brake input so the shifter frees up as designed.

  • Designed to meet or exceed OE performance: gives the technician the quality part needed to get the job done right the first time.
  • Direct-fit replacement: installs in place of the original for straightforward service.
  • Extensively tested to OE specifications: checked to help ensure consistent performance and long service life.
  • Quality-engineered: once installed, helps restore proper transmission shifting function.

If a failed interlock actuator is the reason your shifter won't release from Park, this replaces it. Diagnose the cause before ordering, since shift-lock issues can also stem from the brake switch or wiring.
