How can I activate the intelligent key feature in my Audi A3?

I recently purchased an Audi A3 and there is an intelligent key feature that I am trying to activate. Does anyone know how to do this?

To activate the intelligent key feature in your Audi A3, simply follow these steps: 1. Press and hold the unlock button on your key fob for 5 seconds. 2. While still holding the unlock button, press the lock button 3 times. 3. Release both buttons and the lights on your Audi A3 should flash, indicating that the feature has been activated.

I had trouble activating the intelligent key feature in my Audi A3 as well. I found that following the instructions in the owner's manual helped me successfully activate it.
