OK, this has got me boiling. I got the plain key but I cannot open the door southeast of the lever! It gives me the magically locked message if I try to pick it or bash it. I'm pretty sure I have all the keys I've accumulated through the dungeon but I can't open the dang door. I went and looked at the walkthrough after a frustrating half hour and it doesn't say anything about the door thats giving me troubles. Please, someone, help!

I would like to help but what chapter are u on? what place? i am not sure if you are talkin about vales. If u are talkin about that then there is a key to open that door. Check all around you if u dropped anything i forgot who has the key but u gota open the top one first to get to the bottom one theres a very nice necklace there so dont skip it
