For the transcoding process, you can choose the outer and or inner door line. The door first needs to be opened, and then put a special individual key in the lock of the castle, which goes in a set with the lock itself. The key is rotated until the latch appears. Further into the cavity located under the well, a certain device is inserted, which must be pressed on the insides of the well until it stops. Then again a special key is used. He turns against the movement of the watch arrow until the characteristic click appears, which is a kind of command to pull out the key. See more detailed instructions on the site 2.PHP.
