The Dorman 924-730 ignition lock cylinder is a direct-fit replacement designed to restore ignition switch function on specified Ford, Lincoln and Mercury vehicles when the original cylinder is worn or damaged.

If your key won’t turn, the ignition feels loose, or the cylinder shows wear, replacing the lock cylinder can bring back reliable starting and steering lock security without the expense of an entire steering column assembly. Dorman engineers this part to match the original equipment’s fit and operation so installation is straightforward for DIYers and professional technicians alike. Before purchasing, confirm vehicle compatibility by entering your exact year, make and trim in the garage fitment tool.

Replacing only the cylinder is a targeted repair that often saves time and money versus replacing the whole column.
