2. The SmartKey (FBS3 System)
Introduced in the late 1990s, the SmartKey changed the metal blade with an infrared signal. When the key is placed into the Electronic Ignition Switch (EIS), it performs a "handshake" with the car's computer. If the codes match, the guiding lock is released and the car starts.
3. Keyless-Go and FBS4
The modern-day age utilizes the FBS4 (Fahrberechtigungssystem 4) system.
