Understanding the Technology: Why Do Keys Need Reprogramming?
Modern automobiles use a mix of mechanical and electronic parts to guarantee security. The main technology at play is the transponder system. Introduced in the mid-1990s as a response to rising car theft, transponders utilize Radio Frequency Identification (RFID) to interact with the automobile'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 out a signal to the transponder chip inside the key. If the unique code kept in the key matches the code set into the car's immobilizer, the engine is allowed to start. If the codes do not match, the fuel system is disabled, and the car stays fixed.
