Same key system as the 2000–2013 E-Class

Mercedes-Benz kept the E-Class's key system unchanged across 2000–2013, so everything about replacing a 2006 key — blanks, programming, and what happens if every key is lost — matches the rest of that run. The full year-by-year breakdown lives in our Mercedes-Benz E-Class key guide.

What drives the price is the key type, whether you still have a working key, and where the car is parked. There's more on Mercedes-Benz programming in general on our Mercedes-Benz key page.
