X AUTOHAUX Front Door Lock Cylinder Pair for Ford & Lincoln - 2 Keys, OE 7C3Z-1521990-A

This is a pair of front door lock cylinders with two keys (OE 7C3Z-1521990-A) designed to replace worn or damaged locks on compatible Ford and Lincoln vehicles.

When a door lock cylinder sticks, won’t turn, or the key won’t engage, swapping in a matching replacement cylinder restores normal door locking and handle operation. The X AUTOHAUX set includes both driver and passenger front cylinders, two matching keys and C-clips so you can complete the service in one visit without hunting for parts. These metal tumblers are built to resist rust and wear and are made to fit the listed Ford and Lincoln models — check the part number and vehicle fitment before ordering.
