If you are talking about the silver knight then the key is just outside the castle in a crack in the floor by the bridge entrance, make sure you sign up for the mission properly. if however you need the key to the temple at the blue diamond chasm then find the battery and piece of the winch handle in the long grass, get the spade first by repairing the handle of the winch, you can just see where the handle broke off!, its on an angle,click the end of the handle and the spade comes up, leave it there and put the battery into the top of the detector near the handle where a little oblong shape is, turn up the sound and move the detector as if giving your screen a paint wash, dont miss any part of it, cover every corner!, if you find the scroll move on and get the key,the scroll is not that important!
