Ford Expedition Ignition Lock Cylinder Guide (2011-2017)
If your key is stuck or won't turn in your 2011-2017 Expedition, your ignition lock cylinder may be the problem.
- Symptoms include a key that is hard to turn, gets stuck, or won't start the engine.
- This is a common DIY repair; the new cylinder is re-keyed to your old key, so no programming is needed.
- The OEM Motorcraft part is often priced similarly to aftermarket options, making it a recommended choice.
- Make sure your issue isn't the separate electronic ignition switch or a stuck shifter interlock.
Is Your Expedition's Key Giving You Trouble?
A common issue for the 2011-2017 Ford Expedition is a worn or failing ignition lock cylinder. This can leave you unable to start your truck or, in some cases, unable to remove your key. The symptoms often start small and get worse over time. Recognizing them early can save you from being stranded.
Top 4 Signs of a Failing Ignition Lock Cylinder
- Key is Hard to Turn: You find yourself needing to jiggle or force the key to get it to turn to the 'ON' or 'START' position. This is often the first sign of wear inside the cylinder's tumblers.
- Key Gets Stuck: The key turns to start the engine but won't turn back to the 'OFF' position, preventing you from removing it. This can also be related to the shifter not correctly telling the cylinder it's in Park.
- No-Start Condition: You turn the key, but nothing happens. The dashboard lights may or may not come on. This happens when the cylinder fails to make contact with the electronic ignition switch behind it.
- Key Won't Go In or Comes Out Too Easily: A worn cylinder might not accept the key smoothly, or the key may feel loose and sloppy inside.
Lock Cylinder vs. Ignition Switch
It's easy to confuse these two parts. The lock cylinder is the mechanical lock your key goes into. The ignition switch is the electronic part behind it that the cylinder turns. If you have electrical problems like the radio not working or the engine starting and then immediately stalling, the ignition switch could be the issue, not the cylinder.
Choosing the Right Aftermarket Lock Cylinder
For your 2011-2017 Expedition, you have two main choices: the original Ford part (Motorcraft) or an aftermarket brand like Dorman.
Brand Quality: Motorcraft vs. Dorman
- Motorcraft: This is the Original Equipment Manufacturer (OEM) brand from Ford. Choosing Motorcraft guarantees a perfect fit and the same quality as the part that came with your Expedition from the factory. For this specific part, the price is often very competitive with aftermarket options.
- Dorman: Dorman is a well-known aftermarket company that produces direct replacement parts. Their kits are often designed to be DIY-friendly and may include helpful tools or instructions. For the Expedition, Dorman offers a quality alternative that meets the function of the original part.
Pro Tip: Check the price for the Motorcraft cylinder (part number AU5Z-11582-B is a common one 🎬 Watch this step-by-step guide to replacing the AU5Z-11582-B cylinder.) before you buy. Since the cost is often similar to aftermarket versions for this part, going with the original Ford part is a smart choice for guaranteed compatibility.

Frequently Asked Questions (FAQ)
Can I replace the ignition lock cylinder myself?
Yes, this is a very DIY-friendly repair. The process usually involves removing the plastic covers around the steering column, turning the key to the 'run' position, and pressing a small release pin to slide the old cylinder out. 🎬 See how to remove the cylinder and code the new keys. The new cylinder must be coded to your existing key, which involves swapping small tumblers from the old unit to the new one or using the new tumblers provided in the kit.
🎬 Watch a detailed walkthrough on how to rekey your new cylinder.Do I need to reprogram my keys after replacing the cylinder?
No, as long as you re-key the new cylinder to match your original key. The replacement kits are designed for this. Your vehicle's anti-theft system (PATS) recognizes the chip in your key, not the cylinder itself. By keeping your original key, you avoid any need for expensive reprogramming.
My key is stuck and won't turn. How can I replace the cylinder?
This makes the job harder, as the key must be in the 'run' position to press the release pin. Before assuming the cylinder is bad, try wiggling the steering wheel and the gear shifter to make sure nothing is in a bind. If it's truly seized, the cylinder may need to be drilled out by a mechanic or locksmith.
Are there any recalls for the ignition lock cylinder on my Expedition?
No, there are no recalls from Ford or NHTSA for the ignition lock cylinder on the 2011-2017 Ford Expedition. A Ford Special Service Message (SSM 51122) for newer trucks notes that debris can cause the key to stick, and recommends trying to vacuum the cylinder out before replacement.
