How to Reprogram Audi Keys


Instructions
1. Place one of the keys in the ignition and twist it one click forward. This will turn on your car without starting the engine.
2. Exit the car and shut the door.
3. Lock the driver's side door with the second key. Do not use the remote.
4. With the key in the door, press the key's "unlock" button once. The headlights on your Audi will blink twice, but your doors will stay locked.
5. Unlock and re-lock the door with the key. Do not use the remote.
6. Remove the key from the door and the key from the ignition, and check whether the reprogramming was successful.
7. Repeat the process, but switch the keys: put the programmed key in the ignition and, put the unprogrammed key in the door lock.
