Is Your Navigator's Ignition Switch Failing?
A bad ignition switch can cause some very confusing problems. Because it controls power to so many different parts of the vehicle, the symptoms can seem unrelated. 🎬 Watch: 5 warning symptoms of a bad ignition switch. One of the most serious issues is the engine stalling while you're driving, which can happen if the switch's internal contacts wear out and lose connection over a bump. You might also find the vehicle won't crank at all, or it starts for a second and then immediately dies.
Key Generation Difference
This guide and the aftermarket parts listed primarily cover the 2007-2017 Lincoln Navigator, which uses a traditional key and a mechanical ignition switch in the steering column. The 2018-2019 Navigator uses a different push-button start system. While some symptoms can be similar, the part itself is different and not interchangeable.
Choosing the Right Aftermarket Ignition Switch
When replacing the ignition switch on your 2007-2017 Navigator, you have several options. The choice often comes down to a balance of price, quality, and your confidence in the brand.
- Motorcraft: This is Ford's official parts brand, making it the Original Equipment (OE) choice. It guarantees a perfect fit and the same quality as the part your Navigator was built with. For critical electronic parts, many mechanics and owners prefer to stick with Motorcraft to avoid potential issues, even if it costs a bit more.
- Standard Ignition (SMP): Standard Motor Products is a highly respected aftermarket manufacturer. They are often considered an OEM-equivalent, providing excellent quality and reliability that's very close to the original part. This is a solid choice if you want OE-level performance without the OE price tag.
- Rostra Powertrain: Rostra is known for various electronic components. They are generally seen as a reliable mid-tier brand that offers a good balance of cost and quality for a daily-driven vehicle.
- True Tech / Replacement: These brands typically represent the value end of the market. They offer the most budget-friendly prices, making them a good option for a quick fix or if the cost is your main concern. However, the long-term durability and precision of fit might not match the premium brands.
Known Issues, Recalls, and TSBs
Searches for the 2007-2019 Lincoln Navigator did not reveal any specific recalls or widespread Technical Service Bulletins (TSBs) directly related to the ignition switch itself. However, recalls for other electrical issues that could present similar symptoms have been issued. For example, a recall for 2020 models involved a short circuit in the battery junction box causing a fire risk. Another recall for 2015-2017 models concerned exterior mirror lights short-circuiting. Always check for any open recalls on your specific vehicle using your VIN on the NHTSA website.

| OEM Ignition Switch | $65 - $100 |
| Shop Labor | $106 - $155 |

Frequently Asked Questions
Can I replace the ignition switch myself?
Yes, this is a DIY-feasible job for someone with basic tools and patience. It involves removing the plastic shrouds around the steering column to access the switch. You will need to disconnect the battery and be careful with the various electrical connectors. The switch itself is usually held in with just a screw or two.
Do I need to reprogram my keys after replacing the switch?
No. When you replace only the electronic ignition switch, there is no need to reprogram your keys. The anti-theft system information is stored elsewhere. Reprogramming is only necessary if you replace the ignition lock cylinder or the keys themselves.
Will a bad ignition switch cause a Check Engine Light?
It can, but not always. If the switch causes the engine to stall or provides inconsistent power to the engine's computer or sensors, it can trigger fault codes. However, many ignition switch failures, like a simple no-start, won't illuminate the light.
What's the first thing to check if my Navigator won't start?
Before suspecting the ignition switch, always check the simplest things first: the battery and the starter. A dead battery is the most common cause of a no-start. If the battery is good but you hear a single click or nothing at all, the starter solenoid or the ignition switch are the next logical culprits.
