2. The SmartKey (The "Black" or "Chrome" Fob)
Introduced in the late 1990s, the SmartKey removed the conventional metal blade for beginning the car. Rather, it uses an infrared (IR) beam. The "Chrome" version is merely a more modern-day, aesthetic upgrade of the original black plastic fob, though it frequently includes better durability.
3. Keyless-Go and Keyless-Entry
