Ford C-Max Ignition Switch Guide for 2013-2018 Models
Having trouble starting your Ford C-Max or dealing with strange electrical problems? Your ignition switch might be the culprit.
- Failure symptoms include the car not starting, the key not turning, and random electrical problems.
- A recall (15C06) exists for some 2015 models where the engine won't shut off, which requires a dealer software update.
- Replacement is a straightforward DIY task for most owners, typically taking less than an hour.
- You may only need the electronic switch, but some problems require replacing the mechanical lock cylinder as well.
Is Your C-Max Ignition Switch Failing?
When an ignition switch starts to go bad, it can cause problems that seem unrelated. Because it controls power to so many components, a failure can be tricky to diagnose. The most common issues are often mistaken for a dead battery or a bad starter.
Common Symptoms of a Bad Ignition Switch:
- Key Won't Turn: You might find the key is difficult to turn or gets stuck in one position. This can sometimes be due to a worn-out key or a problem with the lock cylinder itself.
- Car Won't Start: You turn the key, the dash lights may or may not come on, but the engine doesn't crank. You might hear a click, or you might hear nothing at all.
- Intermittent Electrical Gremlins: Your radio might cut out, your dashboard lights could flicker, or accessories might lose power randomly while driving. This happens when the switch's internal contacts are worn and can't maintain a solid connection.
- Engine Stalls After Starting: The car starts up but then immediately shuts off. This can indicate the switch is failing to keep the ignition circuit powered.
Recall Notice: Engine May Not Shut Off
Ford issued recall 15C06 for some 2015 Ford C-Max vehicles. The issue was that the engine could continue to run even after turning the ignition off. This was caused by a software problem in the Body Control Module, not the mechanical ignition switch itself. Ford dealers can resolve this with a software update, free of charge. While this isn't a direct switch failure, it's a critical safety issue to be aware of for that model year.
Choosing the Right Aftermarket Ignition Switch
When replacing your ignition switch, you don't have to go back to the dealer. Aftermarket parts offer a good balance of quality and value. For the Ford C-Max, brands like Standard Motor Products and Dorman are widely available and are generally considered reliable replacements.
- OEM Equivalent Brands (e.g., Standard Ignition, Dorman): These brands design their parts to meet or exceed the original factory specifications. They are a dependable choice for a direct-fit replacement without the high cost of an OEM part from the dealer.
- Value Brands (e.g., Replacement, True Tech): These brands focus on providing a functional part at the lowest possible price. They can be a good option for budget-conscious repairs, but may not have the same long-term durability or finish as higher-tier brands.
Pro Tip: Many ignition switch issues are actually problems with the lock cylinder where you insert the key. Some aftermarket kits include both the electronic switch and the mechanical lock cylinder. Before you buy, confirm whether you need just the switch or the complete assembly.

Frequently Asked Questions
Can I replace the ignition switch myself?
Yes, this is a DIY-friendly job for someone with basic tools. The process usually involves removing the plastic shrouds around the steering column, turning the key to the 'accessory' position, pressing a release tab, and pulling the old switch out. The new one typically slides right in. 🎬 Watch this step-by-step guide on replacing the ignition switch. The difficulty is low, and it should take less than an hour.
Do I need to reprogram my keys after replacing the ignition switch?
If you are only replacing the electronic ignition switch portion, you will not need to reprogram your keys. However, if you are replacing the lock cylinder (the part your key goes into), you will either need to have the new cylinder matched to your old key or program the new keys that come with it. Some Dorman kits come with a tool to help with this process.
🎬 Watch Dorman's video on repairing the ignition lock cylinder.My key won't turn. Is it always the ignition switch?
Not always. First, try wiggling the steering wheel back and forth while gently trying to turn the key, as the steering lock can bind the ignition. Also, make sure your vehicle is in Park. If that doesn't work, the problem could be a worn key, a bad ignition lock cylinder, or the ignition switch.
What's the difference between an ignition switch and an ignition lock cylinder?
The ignition lock cylinder is the mechanical part you put your key into. The ignition switch is the electronic part behind it that actually sends power to the vehicle's systems. They are separate components but work together. Sometimes they are sold as a complete assembly.
