Every modern-day Audi key consists of a transponder. When the ignition button is pushed, the car sends out an electromagnetic field that powers the chip in the key. The key then sends out a distinct code back to the car. If the code matches the one saved in the Audi Immobilizer system, the engine is allowed to begin.
