Clammed Room Escape

You are very tired and can not even wait until going home from work. You have decided to remove a quiet and comfortable room at the hotel across the street. You paid to the manager at the bottom and took the key from him, but when you came in and closed the door, then heard the click of the lock. The door is locked from the outside, and now you're trapped. You need to concentrate and try to find another way to get out of the room. Look for items that will help to pass all the tests.
