Why Audi Keys Are More Than Just "Remotes"
The primary reason that a new Audi key can not be just cut at a regional hardware store is the integrated Immobilizer System. Inside every contemporary Audi key is a transponder chip that interacts with the automobile's Electronic Control Unit (ECU).

When the key is placed or brought into the cabin, the ECU sends an ask for an unique security code. If the key's responder offers the proper, encrypted code, the engine is allowed to begin.
