I have missed the key of Watcher's Keep Dungeon

[Hamletxx82]

I have missed the key of Watcher's Keep Dungeon Level1 to enter the northeast room for completing ritual.Unfortunately I didn't notice it unless I begin to play Throne of Baal.I dont know where I drooped it cuz i only use quick saves.How can I enter it without key.Is there any site for missing items? I even searched for some sites (for Cheating) to create and edit items.But they re only for normal or magical items ,not quest items.Please if u know someting help me.I have made level 25 cavalier and i dont want to finish game without playing Watcher's Keep.My e-mail Deemer@mynet.com.please.I am waiting
