Ford Expedition Ignition Switch Guide: 2016-2023 Problems and Replacement
Is your Expedition having trouble starting, or stalling unexpectedly? Your ignition switch might be the problem.
- A failing ignition switch is a critical safety issue; do not drive if you suspect it's bad, as the engine could stall.
- For keyed ignitions (2018-2022), try vacuuming the keyhole first to clear debris as suggested by Ford's service message SSM 51122.
- Symptoms often mimic a dead battery or bad starter, but a faulty switch usually causes a silent no-start or random electrical issues.
- Replacing only the electrical switch component typically does not require expensive key reprogramming.
Is Your Ignition Switch Failing? Common Symptoms
A bad ignition switch can cause confusing problems that might seem related to the battery or starter. Here are the most common signs for the 2016-2023 Ford Expedition.
- Engine Won't Crank or Start: You turn the key or press the button, and nothing happens. The engine doesn't even try to turn over.
- Stalling While Driving: This is a serious safety issue. A worn switch can lose connection over bumps, shutting the engine off without warning. This also causes a loss of power steering and brakes.
- Intermittent Electrical Problems: You might see dashboard lights flicker, or the radio and climate control might cut out and turn back on randomly.
- Key Is Hard to Turn: If your key feels sticky, gets jammed, or is difficult to turn, the problem could be the switch or the lock cylinder it connects to.
- Starts, Then Immediately Stalls: The engine might fire up but die as soon as you let go of the key. This can happen if the switch fails to keep the 'ON' circuit powered.
- Push-Button Start Issues: For trucks with this feature, you might need to press the button multiple times to get the engine to start, or you may see a "No Key Detected" message even with the fob inside. 🎬 Learn how to start your truck with a dead key fob.
Pro Tip for Keyed Ignitions
For 2018-2022 Expeditions without push-button start, Ford issued a Special Service Message (SSM 51122) for keys that are hard to turn. Before replacing parts, try vacuuming the ignition lock cylinder for 30 seconds to remove any debris that might be causing the jam.

When buying a replacement, you have options ranging from OEM to various aftermarket brands. Since this is a critical electrical part, quality matters.
Brand Quality Tiers
- OEM (Motorcraft): This is the original part your Expedition came with. It guarantees perfect fit and function. For critical electrical components, many mechanics recommend sticking with Motorcraft to avoid compatibility issues.
- Premium Aftermarket (Standard Ignition): Brands like Standard Motor Products (SMP) have a strong reputation. They are known for making high-quality parts that meet or exceed original specifications and are trusted by many professional technicians.
- Mid-Grade Aftermarket (Dorman): Dorman is a popular brand with mixed reviews. Some of their parts are known for improving on factory designs, while others have had reported issues with fit or durability. It can be a cost-effective choice, but may carry more risk than a premium brand.
- Economy Aftermarket (Replacement, True Tech, VNE, Rostra): These brands offer the lowest price point. While they can get your truck running again, they may not have the same long-term durability or quality control as more expensive options. They are best suited for budget-focused repairs.
An Important Note on Ordering
Your Expedition could have a traditional keyed ignition or a push-button start system. These two types of switches are not interchangeable. Always verify which system your vehicle has before placing an order.

Frequently Asked Questions
Do I need to reprogram my key after replacing the ignition switch?
Usually, no. If you are only replacing the electronic switch portion and reusing your original key and ignition lock cylinder, no reprogramming is needed for the anti-theft system.
Is this a difficult DIY job?
For most people with basic hand tools, this is a manageable DIY repair. It typically involves removing the plastic covers around the steering column, unplugging the old switch, and bolting the new one in. The entire job usually takes about an hour.
Are there any recalls for the 2016-2023 Expedition ignition switch?
No, there are no active recalls specifically for the ignition switch on these model years. There is a Ford service message (SSM 51122) for keyed ignitions that get stuck due to debris, but this is not a safety recall.
My truck makes a clicking sound but won't start. Is it the ignition switch?
Probably not. A rapid clicking noise usually points to a weak or dead battery. A single, loud click often indicates a problem with the starter motor or solenoid. A bad ignition switch typically results in silence when you try to start the engine.
