Market analysis
Why does the Ford Expedition ignition switch cost more?
A used Ford Expedition ignition switch carries a median asking price of $125, which is 20% higher than the Mercedes S Class at $100. Supply also plays a role: Mercedes S Class has 2,031 priced listings versus 609 for Ford Expedition, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 87% of Mercedes S Class listings compared to 62% for the Ford Expedition, so buyers looking for top-condition units will find more options on the Mercedes S Class side.
The Mercedes S Class average ($130) runs 30% above its median ($100), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 11 model years for the Ford Expedition (2015–2025) but only 9 for the Mercedes S Class (2015–2023), so the Ford Expedition data reflects a broader range of generations.
The Ford Expedition ignition switch is interchangeable across 22 model years versus just 10 for the Mercedes S Class — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Mercedes S Class is 33% cheaper ($100 vs $150) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used ignition switch
- Determine if the unit includes the mechanical lock cylinder with matching keys, or if it is purely the electrical ignition switch contact block.
- Match key transponder chip frequency (Passlock, PATS, or RFID) and verify if anti-theft relearn or key programming tools will be required.
- Inspect wire harness pigtail connectors for burnt plastic or loose female spade terminals caused by ignition circuit overload.
- Verify key cylinder positions (Accessory, Off, Run, Start) turn smoothly without sticking, binding, or requiring key jiggling.
