Lost Audi A3 Locking Wheel Nut - What are my next steps?
 

So, I've misplaced my A3 locking wheel nuts and I have been told they are unobtainable from standard garages. One forum even said that contacting Audi themselves will be useless as they do not provide you with a new one.

Where can I find another one? What are my options?

Also, where can I find the key code?
