How I can open this lock the door closed?

I closed the door of my room. Blocking does not have screws holding the sides at the door, but below the handle on the bottom is a small hole a little smaller than the diameter of a pea. I'm guessing from your kind of concealment that has something to do with the opening of the same. Any ideas?

Ask the real owner of the lock if you can borrow your key!?!?
