Market analysis
Why does the Mercedes S Class ignition switch cost more?
A used Mercedes S Class ignition switch carries a median asking price of $100, which is 1% higher than the Kia Sportage at $99. Supply also plays a role: Mercedes S Class has 2,031 priced listings versus 661 for Kia Sportage, and more listings generally mean more choices and more competitive pricing.
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 Kia Sportage (2015–2025) but only 9 for the Mercedes S Class (2015–2023), so the Kia Sportage data reflects a broader range of generations.
The Kia Sportage ignition switch is interchangeable across 15 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.
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.
