Technical characteristics of the Mercedes remote

The original manufacturing ensures a proper fit for the ignition switch socket or keyless entry system (depending on the car's configuration), as well as appropriate communication with factory controllers. This allows the key fob to be used as a basis for repairing, refurbishing, or restoring the functionality of an existing set.
