Luxury House Escape

This is the 214th escape game from Enagames. Assume that i was invited by my collage-mate for a normal visit to see his luxury house and for some help in his project work. I went to his sweet home, no one is there except me and my friend. Late night, in the comfort of his luxurious house, I felt asleep. When I woke up, I found myself alone in the house. My friend is missing at the house!!! I strike doors heavily and shouted at the top of my voice, but no response. I think the door might be locked outside. Will you please help me to find the spare key to open the door..?. Click on the objects to interact and solve the puzzles. Play enagames and have fun..
