Dorman Ignition Lock Cylinder Housing OE FIX — Direct-Fit for Ford/Mazda/Mercury, Thicker Cam & Shear Bolt Included

Replacement ignition lock cylinder housing engineered to fix the factory cam weakness and restore reliable steering column operation in select Ford, Mazda, and Mercury vehicles.

If your steering column is binding or the ignition switch isn't engaging smoothly, the Dorman 989-019 OE FIX ignition lock cylinder housing addresses a known durability shortcoming in the original equipment. This direct-fit replacement uses a thicker internal cam, improved materials, and includes a new shear bolt so you can complete the repair and return the vehicle to normal starting and steering behavior. Fitment applies to specific model years—verify your exact trim with the vehicle garage tool before ordering.

Will this part fit my car?

Compatibility is limited to certain Ford, Mazda, and Mercury models and years. Always confirm compatibility by entering your vehicle's year, make, model, and trim into the seller’s garage tool to avoid installation issues.

• Compatible models: Ford Escape (2008–2010), Ford Focus (2009–2011)
• Mazda Tribute (2008–2011)
• Mercury Mariner (2008–2010)
• Use the garage tool to confirm trim-level fit before purchase

How does the OE FIX design improve durability?

Dorman's OE FIX version solves a recurring failure mode by reinforcing the component that transmits key-turn motion. The internal cam is thicker and more rigid to resist wear and deformation that can lead to jamming or inconsistent ignition engagement.

• Thicker internal cam to reduce flex and premature wear
• Stronger mating surfaces for improved longevity
• Material selection tuned for durability under repeated use

What comes in the box and what do I need for installation?

This unit ships ready for installation and includes a replacement shear bolt so you won’t need additional hardware for a typical swap. Basic hand tools and access to the steering column are required; professional installation is recommended if you’re not comfortable with automotive repairs.

• Includes ignition lock cylinder housing with thicker internal cam
• Includes new shear bolt for secure installation
• Pre-lubricated with silicone grease for smoother initial operation
• No extra parts usually required—verify instructions for your vehicle

How is quality verified for this replacement part?

Dorman performs both material testing and vehicle try-on validation to ensure the part meets fit and function expectations. These checks reduce the chance of fitment problems and help confirm the revised cam geometry resolves the original issue.

• Vehicle try-on testing for fit verification
• Material testing for strength and wear resistance
• Manufactured to address specific OE failure modes
