The Drunken Lizard Pub

Is there anybody who has made a list of what key goes where?
I have a "Heavy Key" which I have no idea where I picked up or where it goes. And also the "Gate Key" from darkford... where the heck does that one go?
Oh, and also a "Fancy Key"...

keys, keys, keys...


Thanks in advance...

edit: got the "gate key" done, it works on... the gate!!!
