Spot on.
Right the process doesn't need vagcom with 2 keys. This is from memory, which I am 90% sure is correct.
Put 1 key in ignition and turn to the position where battery light etc light up. Lower drivers window (Safer). Close the drivers door again- window open and key in ignition. Put the second key in the drivers lock. Turn it open/closed constantly whilst pressing the remote open/close buttons alternately. The car should chirp IIRC when done. Open door and put window up again. Test the remote function works. Smile smugly knowing you saved £££
