Fake or real?

Klaus walked up to the door. The door wasn't anything like an ordinary one. It was made completely from earth. It only had a knob and a key hole in it giving it the appearance of a door. Klaus not wasting anytime placed the shining golden key he retrieved hanging above in the air into the key hole and turned the key to open the door.

Seconds later, a clicking sound was heard followed by a mechanical screech. Then a loud sound like that of a house collapsing followed. And what was expected next never happened. Instead of the door itself to come unlock, the entire maze began to quake and soon enough, it began to descend back into the ground where it came from.
