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

When the key is inserted or brought into the cabin, the ECU sends out a demand for a distinct security code. If the key's responder supplies the appropriate, encrypted code, the engine is permitted to begin. If the codes do not match, the fuel system is handicapped, preventing theft.
