ook i am stuck and cant find the 3rd key to pass the gates and continue on, any help

Since there are 4 keys and the level is an "open" one, if you don't explain to us which keys you got, it will be hard for us to help you.

im gusssing one of the keys u missed is from the haunted halls. There is a presure plate n there that opens a wall on the other side - u have to lure those skeleton leginarries onto the pressure plate while u then book it to the open wall - 1 key is in there.
