Even after getting the Solider Key, the door you need to enter in order to move onto the next part says "Door is locked" still. During my first run through, after defeating the pursurer, I ran back to the bonfire because I needed to heal, not realizing I should have examined the bird nest first. So when I went back to that direction, the door said it was locked. Do I have to start over?
