<h1>2020 Audi TT Keyless Entry Remote Fob (Smart Key)</h1> <p><font size="3"><b>Important:</b> The 2020 Audi TT does not support onboard programming for smart key remote fobs. Programming requires advanced diagnostic tools compatible with Audi systems. </font></p> <p><font size="3"><b>Step-by-Step Programming Instructions:</b> </font></p> <ul> <li><font size="3">Step 1: Confirm Key Compatibility Ensure that the replacement smart key fob is compatible with the 2020 Audi TT and has not been previously linked to another vehicle. </font></li> <li><font size="3">Step 2: Prepare the Vehicle Ensure the car is in Park with the engine off. Leave the driver's door open; all other doors should be closed. Confirm that the vehicle battery and the key fob battery are fully charged. </font></li> <li><font size="3">Step 3: Connect Diagnostic Equipment Plug a VAG-compatible diagnostic tool (such as ODIS or VCDS) into the OBD-II port under the dashboard. Launch the software and connect to the vehicle’s control modules. </font></li> <li><font size="3">Step 4: Access Security System Navigate to the Immobilizer or Key Coding section.
