<h1>2018 Audi TT Keyless Entry Remote Fob (Smart Key)</h1> <p><font size="3"><b> Important:</b> The 2018 Audi TT is not onboard programmable for smart key remote fobs. Programming requires the use of specialized diagnostic tools compatible with Audi’s vehicle security systems. </font></p> <p><font size="3"><b>Step-by-Step Programming Instructions:</b> </font></p> <ul> <li><font size="3">Step 1: Confirm Remote Compatibility Make sure the replacement smart key is designed specifically for the 2018 Audi TT and has never been programmed to another vehicle.</font></li> <li><font size="3"> Step 2: Prepare the Vehicle for Programming Ensure the vehicle is in Park with the ignition OFF. Close all doors except the driver’s. Ensure the vehicle’s battery is fully charged to prevent interruption. </font></li> <li><font size="3">Step 3: Connect Diagnostic Equipment Connect an Audi-compatible diagnostic tool (such as ODIS, VCDS, or similar) to the vehicle’s OBD-II port, typically located under the dashboard on the driver’s side. Start the software and initiate communication with the vehicle systems. </font></li> <li><font size="3">Step 4: Access Key Adaptation Settings Navigate to the immobilizer or key adaptation menu using the software. Enter the vehicle’s security access code (PIN/SKC) if prompted. </font></li> <li><font size="3">Step 5: Begin Smart Key Programming Choose the option to add new keys or adapt keys to the vehicle. Place the smart key inside the car near the recognized signal area (usually near the push-button start). Follow on-screen prompts to program the key. </font></li> <li><font size="3">Step 6: Program Additional Keys (If Required) Repeat the programming sequence for each additional key, ensuring they are present at the time of programming. Audi systems typically allow up to 8 keys to be programmed. </font></li> <li><font size="3">Step 7: Complete Programming Process After successful programming, the software will confirm completion. The vehicle may cycle the door locks or display a confirmation on the dash. </font></li> <li><font size="3">Step 8: Verify Key Functions Test each programmed key fob to ensure proper operation of: Lock/unlock functions Trunk release Push-button start Passive entry (if equipped) </font></li> <li><font size="3">Step 9: Disconnect Equipment and Final Check Close the session in the diagnostic software. Disconnect the tool from the vehicle. Retest each key to verify all functions are working as expected. </font></li> </ul> <p><font size="3"><b>Additional Tips:</b> </font></p> <p><font size="3">Make sure smart keys have a fully charged battery before programming. All keys must be present during the session to retain their pairing. If any step fails, restart the process from Step 1 with a fresh session.</font></p>
