That chrome key everyone likes to show off? It is a $300+ electronic device. Mercedes uses infrared for ignition and radio frequency for proximity entry. Star-diagnostic-level programming is required. We get most Mercedes calls from the Montecito Heights area and along Fountaingrove Parkway. The dealer in Marin charges $500+ for a C-Class key. We drove to a GLC owner's house on Brush Creek Road, programmed the key, $300 flat.
