<h1>2015 Audi TT Keyless Entry Remote Fob (Smart Key)</h1> <p><font size="3"><b>Important Note:</b> The 2015 Audi TT does not support on-board programming. All remote fob programming must be performed using specialized diagnostic equipment that can interface with the vehicle’s immobilizer and keyless entry system.</font></p> <p><font size="3"><b> Step-by-Step Programming Instructions:</b> </font></p> <ul> <li><font size="3">Step 1: Verify Smart Key Compatibility Ensure the replacement smart key fob is specifically compatible with the 2015 Audi TT and has not been previously programmed to a different vehicle. </font></li> <li><font size="3">Step 2: Prepare the Vehicle for Programming Place the gear selector in Park. Ensure all doors are closed and the vehicle is turned off.

Start the diagnostic program on your interface device. </font></li> <li><font size="3">Step 4: Access the Immobilizer System Within the diagnostic software, navigate to the Immo/Key Learning Module. When prompted, input the security PIN or SKC code associated with the vehicle. </font></li> <li><font size="3">Step 5: Program the New Smart Key Follow the on-screen prompts to register the new remote. If additional remotes are to be programmed, they must be registered during the same session. </font></li> <li><font size="3">Step 6: Confirmation Once the smart key has been successfully registered, the system will confirm programming. If programming fails, restart the process and verify that the key is compatible and not previously coded. </font></li> <li><font size="3">Step 7: Function Check Test all programmed remote functions: Lock/Unlock doors Trunk release Remote start or push-button ignition (if equipped) Panic alarm </font></li> <li><font size="3">Step 8: Program Additional Keys (Optional) Repeat Step 5 for each additional remote.
