broken door lock

[hucqym]

the door lock on my 2001 boxster broke and i took things apart. Seen various posts on broken doorlocks and folks have had different failure mechanisms and so I decided to just share the video of my failure mode to determine the best fix.

The door lock part itself seems to be okay and the plastic connecting piece to the handle etc.. seem fine. The key mechanism seems to be the culprit. The key rotates 180degrees freely without any resistance and the metal piece does not rotate. But if I rotate the metal piece itself then I can get the key to correspondingly rotate. Please tell me I am just missing a silly <$20 part that I can easily replace. It would suck to have the whole assembly replaced.

thought I should update this. It did turn out to be a silly 2c part that needed replacement. (Ofcourse the replacement kit costs orders of magnitude more than that, but still significantly cheaper than waht porsche wants me to replace)
See this other DIY article and that was the exact part I had broken as well.

Must note, however, that the ebay part is of pretty cheap grade and I am afraid it might have a short life too. I'll try to find a genuine audi replacement part somewhere if I can.
