By the 1980s, the "switchblade" style key was presented, where the metal blade would fold into a plastic fob. This era likewise saw the intro of basic infrared (IR) remote locking, though the engine still required a physical turn of the blade.
2. The SmartKey Revolution (1997-- 2010s)
In 1997, Mercedes-Benz revolutionized the industry by presenting the "SmartKey." This was a plastic fob with no visible metal blade for the ignition.
