6. Remove the inner lock handle (see "Replacing the front door window regulator").

18. Install the new lock in the reverse order of removal, having previously lubricated all rubbing parts with consistent grease. Check the ease of opening and the reliability of closing the door lock. Adjust the lock if necessary.
19. To adjust the lock, loosen the fastening screws and move the lock:
- a) outward if the door closes tightly;
- b) inside if the door does not close tightly;
- c) downwards, if the door rises when closing.
After adjustment, tighten the screws. Use an impact screwdriver to loosen and tighten the screws.
Helpful Hint: If you need to remove the retainer, trace its outline on the body pillar first. This will help maintain the lock adjustment when installing.
