Which vehicles will this kit fit and how do I confirm compatibility?

This kit is built to match the original lock assemblies on many Ford, Mercury and Lincoln models from the early 1990s through the late 1990s. Before purchasing, cross-check part numbers and year/model details to ensure a match to the original equipment in your vehicle.

• Common fits include Ford F-150/F-250/F-350 (1993–1996) and E-series vans (1992–1995).
• Covers Bronco, Crown Victoria, Mustang, Explorer, Taurus, Thunderbird, Windstar and select Lincoln models.
• Replaceable OEM numbers referenced: C-42-150, DP-42-122, F3UZ1522050D, F2UZ1522050A and related codes.
• Always verify using your vehicle VIN or the original part number for exact fitment.

How straightforward is the installation for a non-professional?

Installation is intended to be a direct replacement using the same mounting points and linkages as the factory part. Basic hand tools and a modest amount of mechanical aptitude are usually sufficient; however, some models may require panel removal or steering column disassembly.

• Direct-fit design minimizes modification—bolts and clips align with the original locations.
• Keys arrive matched to the supplied locks so programming or rekeying is not typically required.
• Remove the old cylinder, swap in the new unit, and reattach any retaining hardware and electrical connectors.
• If unsure, consult a repair manual or professional for models with more complex steering column access.

What quality and durability features does this replacement offer?

Fit4drive manufactures this lock set from robust materials and performs factory testing to help ensure consistent operation over time. The components are engineered to align with OEM specifications so they replicate the original performance and fit.

• Constructed from corrosion-resistant metals and precision components for smooth key action.
• Tested assemblies reduce the chance of premature wear or jamming compared to unknown aftermarket parts.
• OEM-style fit and tolerances designed to match mounting points and electrical interfaces.
• Packaged with customer support and fitment reminders to verify your application before installation.

What should I check before ordering to avoid returns?

Confirm the exact model year and original part number from your vehicle to ensure the replacement matches. Take note of any variations (factory options, steering column gestures, or regional differences) that could affect fitment.

• Cross-reference listed part numbers such as F3UZ1522050A with your current lock casting.
• Verify the vehicle make, model and year range (e.g., Ford Ranger 1995, Mercury Sable 1990–1995).
• Contact the seller with your VIN or photos if you need help confirming compatibility.
• Keep the original parts until the new unit is fully installed and tested.
