Among the most common questions Audi owners ask is why a spare key carries a superior cost tag. The response lies in the Immobilizer System. Every Audi key produced since the mid-90s contains a transponder chip. When the key is placed or spotted, the car's Engine Control Unit (ECU) sends out a difficulty code to the key. If the key does not respond with the appropriate encrypted code, the engine will not start.

Modern Audi keys use "rolling codes," indicating the code modifications each time the car is started. This makes it essentially impossible for burglars to "get" the signal and duplicate it. Programming these codes requires specialized software that is frequently restricted to certified car dealerships or high-end automotive locksmith professionals.
