This key usages proximity sensing units to enable the driver to open doors and start the engine while the key remains in their pocket.Audi Connect Key (Digital Key): The latest iteration permits a suitable mobile phone to function as the vehicle key by means of Near Field Communication (NFC) through the myAudi app.Key Type Comparison TableKey TypePrimary FeaturesNormal Model YearsSecurity levelMechanical Flip KeyPhysical blade, remote lock/unlock1997-- 2005ModerateElectronic Key FobPush-button start, immobilizer chip2006-- 2015HighAdvanced Key (Proximity)Hands-free entry, push-start2010-- PresentVery HighDigital Key (Smartphone)App-based, NFC innovation2019-- PresentUltra-High2. Why Audi Keys Are More Than Just “Remotes”
The primary factor why a new Audi key can not be simply cut at a regional hardware shop is the integrated Immobilizer System. Inside every modern Audi key is a transponder chip that interacts with the vehicle’s Electronic Control Unit (ECU).

When the key is placed or brought into the cabin, the ECU sends out a demand for a special security code. If the key’s responder provides the proper, encrypted code, the engine is allowed to start. If the codes do not match, the fuel system is handicapped, preventing theft. Current Audi designs utilize high-level encryption-- frequently 128-bit-- making it virtually impossible to “clone” a key without access to Audi’s central database.

The Future: The Audi Digital Key
Audi is approaching a keyless future. With the Audi Connect Key, owners of more recent designs can utilize their smartphones to lock, unlock, and start their vehicles. This technology uses a protected component in the phone to save the digital signature.
