The modern model of this system is known by the German acronym FBS (Fahrberechtigungssystem). Currently, many Mercedes cars on the roadway utilize either FBS3 or FBS4 innovation.FBS3: Used in most designs from the late 90s to the mid-2010s. These secrets can typically be programmed by specialized automobile locksmiths utilizing particular hardware that reads data from the EIS.FBS4: Introduced around 2013-2014. This is a considerably more protected system with "rolling codes" that are very difficult to replicate. Presently, FBS4 secrets usually require authentication through the Mercedes-Benz main server, making dealership intervention nearly obligatory for replacements.Key Features and FunctionalityModern Mercedes-Benz keys do much more than simply lock and unlock doors.
