The Evolution of Audi Key Technology
The development of Audi's key technology mirrors the brand's slogan, "Vorsprung durch Technik" (Progress through Technology). Over the years, Audi has actually transitioned through several unique iterations of entry systems.

When the key is placed or identified, the car's Immobilizer Control Unit sends out a signal to the chip. The chip needs to react with a special, encrypted code. If the code is inaccurate or missing, the fuel system is disabled, preventing the car from being "hotwired."
Rolling Code Encryption
To prevent "relay attacks" where thieves obstruct the signal from a remote, Audi utilizes rolling code technology. Each time a button is pushed, the key and the car sync to a brand-new, special encrypted code. This ensures that a caught signal becomes useless the moment it is utilized.
