Water Room Escape

[old biker]

On a Sudden Fire Accident the rooms were filled with water and the door was locked automatically. I have to get the room keys to open the doorway before the water increases to dangerous degrees. Help me to get the keys and objects to discharge water from the ceiling.

Good luck
