It occurred to me reading one of the Book 6 posts that we are seeing 
a lot of locked doors in books 1--5.  I'm not sure if I remember them 
all, but feel free to add to the list if I have!


SS-3rd floor hallway door to Fluffy's room--allows trio to realize 
that the Stone is being guarded at Hogwarts, introduces alohamora
  -Flying keys task--alohamora doesn't work, must use an actual key 
to open the door to continue through the puzzles
COS-Most obviously the Chamber itself that can only be opened using 
parseltongue, another new way to open doors!
POA-Secret Passageways-the humpback witch is opened with "dissendium" 
(sp?) the Whomping Willow is opened by pressing a knot on the tree
GOF-Not sure about this one and my copy of the book is out on loan.  
Are there locked doors in GOF-the only one that comes to mind in the 
Prefects Bathroom used to solve Task 2.
OOtP-MOM, Department of Mysteries, mysterious locked door, where 
wizards study something of great power.  
    -DD's office Umbridge finds herself locked out of the 
headmaster's office
    -Umbridge's office-Harry breaks into locked office to speak to 
Sirius.
In all most all of the books we also find Harry locked in his room or 
cupboard at some point and all of the common rooms are protected by 
password operated portraits
The key to the outcome of all of the books, except GOF? involves 
unlocking or opening a door.  Interesting the JKR decided to hide her 
secrets behind a locked door??
