Mercedes-Benz has been a leader in anti-theft technology, which implies the process for duplicating a key depends greatly on the year and design of the car.

Earlier designs used conventional metal keys, in some cases with a standard transponder chip. These are the easiest and least costly to duplicate.

Introduced in the late 1990s, the "SmartKey" replaced the metal blade with an infrared (IR) signal. These secrets do not have a physical "cut" to begin the engine; rather, they are inserted into a plastic slot. The FBS3 system (Fahrberechtigungssystem 3) was the standard for over a decade.

The majority of third-party locksmiths currently can not set FBS4 keys, implying owners of newer designs are often restricted to car dealership services.
