1. The Traditional Blade Key (Pre-1997)
Earlier designs utilized conventional metal keys, sometimes with a basic transponder chip. These are the most convenient and least pricey to reproduce.
2. The SmartKey (FBS3 System)
Introduced in the late 1990s, the "SmartKey" changed the metal blade with an infrared (IR) signal. These keys do not have a physical "cut" to begin the engine; instead, they are inserted into a plastic slot. The FBS3 system (Fahrberechtigungssystem 3) was the requirement for over a decade.
3. The New Generation (FBS4 System)
Starting around 2013-2014, Mercedes presented the FBS4 system. This system features boosted file encryption that is significantly more tough to bypass. Most third-party locksmiths presently can not program FBS4 keys, meaning owners of more recent designs are frequently limited to car dealership services.
