Understanding the Technology: Why Do Keys Need Reprogramming?
Modern automobiles make use of a mix of mechanical and electronic parts to guarantee security. The main innovation at play is the transponder system. Presented in the mid-1990s as a reaction to increasing car theft, transponders use Radio Frequency Identification (RFID) to communicate with the car's Engine Control Unit (ECU).

When a key is inserted 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 stored in the key matches the code configured into the car's immobilizer, the engine is allowed to start. If the codes do not match, the fuel system is handicapped, and the car remains stationary.
