These elements communicate with the key using encrypted information rolling codes. Whenever the key is placed or the "Start" button is pushed, the car and the key perform a digital "handshake." If the codes do not match perfectly, the engine will not begin.
The Evolution of Mercedes Keys
The innovation has evolved through several iterations, typically referred to as "FBS" generations (Fahrberechtigungs System - Drive Authorization System):

This can take anywhere from 10 minutes to an hour depending on the server speed and model.Key File Generation: Once the password is found, a particular key file is generated for one of the empty "tracks" or "slots" in the car's memory (Mercedes lorries generally have 8 key slots).Writing to the Key: The file is composed onto a new, blank Mercedes-style "Chrome" or "Smart" key.Checking: The key is checked in the ignition to guarantee it turns, unlocks the guiding column, and begins the engine.

(Many inexpensive aftermarket secrets only work when placed into the slot).Regularly Asked Questions (FAQ)1. Can I purchase a used Mercedes key on eBay and program it myself?
No. When a Mercedes key is set to a lorry, it is "locked" to that VIN. It can not be reprogrammed to another car utilizing requirement tools. Furthermore, Mercedes keys require specific software and hardware to program; there is no manual onboard series to do it yourself.
2. How long does the programming process take?
