For many owners, the very first instinct is to call the regional car dealership, just to be estimated anywhere from ₤ 400 to ₤ 900 for a single replacement. While the dealer is the most simple route, it is hardly ever the most affordable.

Understanding the Mercedes-Benz Key System

How It Works

If a Mercedes owner has actually lost all their keys, a dealership typically requires the car to be towed to their lot. However, a "Mail-In" service operates in a different way. A specialized service technician needs the car's Electronic Ignition Switch (EIS/EZS) module to set a new key.
