What I noticed is that at the time he was pretending as if he had difficulty opening the door, he was taking the key out of the door and because it was dark in that passage we could not see clearly.  That was the trick he used because when he was pretending as if there was a problem opening that door, it was the time when he was taking the key out.  Because when I was trying to open the key was not there, it was inside with him, so that was a trick because he pretended as if he had difficulties opening the door.
