Escape From Rent House

I have just been transferred to this new city by the company that I work for. I had requested them to arrange for me a rent house and they have done that on my behalf. So, here I have come to the new house in the new city. The house is nice but there is a problem. I accidentally locked the doors when I entered this particular room in the house. I just don’t know where the keys are. They are probably in another room. I am just guessing though. Oh, what a bad start! Now I have to find another way to unlock the door or may be find the keys.
