2. Transponder Keys
Introduced in the 1990s, transponder keys consist of a small electronic chip (transponder) buried in the plastic head of the key. When inserted into the ignition, the car's onboard computer sends a signal to the chip. If the digital code matches, the engine starts. Changing these needs both mechanical cutting and digital programs.
