Symptoms of a Failing Ignition Lock Cylinder
Watch for these clear signs that your ignition lock cylinder needs attention:
- Cylinder is Loose or Falls Out: The most dramatic symptom is the cylinder coming completely out of the steering column, often with the key still in it. This indicates the retaining pin has broken.

- Key Gets Stuck in the Ignition: You may be unable to remove the key 🎬 Watch this video if your key is stuck in the ignition. after turning the car off. While this can sometimes be related to the shifter not being fully in park, it's also a common sign of a bad cylinder.
Choosing the Right Aftermarket Part
When replacing the ignition lock cylinder, you have two main choices: OEM or a quality aftermarket part. For this repair, both are good options, but they have different approaches.
- Motorcraft (OEM): Motorcraft is Ford's official parts brand. A Motorcraft replacement cylinder (like part number SW-6991) is a direct, high-quality replacement. However, it is typically more expensive and is just the cylinder housing, designed to be re-keyed using your original tumblers.
- Dorman (Aftermarket): Dorman is a popular aftermarket brand that offers a complete kit (like part number 924-717) for this repair. These kits are cost-effective and include the new cylinder, a full set of new tumblers and springs, and grease. The major benefit is that you can rebuild the new cylinder to match your existing key, which saves you from having to get new keys programmed.

Frequently Asked Questions
Why did my ignition cylinder just fall out?
