Fitting the Lock on a Volkswagen Polo 9N

Model: Volkswagen Polo MK IV, Polo IV, Polo 4, MK 4, 9N - Years 2001-2009
Part: Door lock

In this video, see how to reassemble the lock on the Volkswagen Polo 9N, from 2001. The YouTuber has precisely indicated the order of assembly of the various parts, numbering them. However, he made a mistake by twisting the spring in the wrong direction: it works the same but does not have the correct tension on the key; the spring must be twisted clockwise. So, following the video, do not make the same mistake! In any case, repositioning the spring is the most difficult part, so do it correctly. Now test the key and refit the entire handle in place.
