How to synchronize and reset the key of the Audi A3/S3 Sportback

Model: Audi A3 Sportback MK 2 - Years 2003-2013
Part: Key

Let's see the key synchronization procedure for an Audi A3/S3: we must be outside the car and have the key to be synchronized with us. The car must be locked. Remove the manual key from the remote. We will activate the learning mode by pressing the "unlock" button once: within the next 30 seconds, we must insert the emergency key into the driver's door lock and turn it to the left once. Now press the "lock" button. This signals the car to finalize the synchronization process. Verify the functionality by trying to unlock and lock the car with the remote.
