Introduced in the mid-1990s as a reaction to rising car theft, transponders utilize Radio Frequency Identification (RFID) to interact with the vehicle's Engine Control Unit (ECU).

When a key is placed into the ignition or brought within proximity of a push-to-start button, the car sends a signal to the transponder chip inside the key. If the unique code stored in the key matches the code set into the car's immobilizer, the engine is permitted to begin. If the codes do not match, the fuel system is disabled, and the car stays stationary.
