My wife is playing and called me to post a question
She has cleared out Nalia's Keep and got the keep key, but she returned to get a flail head she missed and cannot get back in the keep b/c she forgot to put the drawbridge down 
. The secret entrance is also not accessible....is there any other way into the keep? Even willing to try a cheat.....thanks
