The Rest of the Car Is the Same Age as the Key
A battery door that snapped off is usually not the only tired plastic on a fifteen-year-old Mercedes. These are the parts that go at the same time, and they take about as long to fit.
And If You Want More Than Cosmetics
This key fits the W204 C-Class, W212 E-Class and X204 GLK. We build hardware for every engine those cars came with — headers, downpipes, intakes, cooling and ECU work.
