Escape My Dad

In which a dad just came home from a business travel. As he was very tired, he asked his kid to go and play outside, so he could rest. So the kid left to play with his friends and locked the dad inside the house. The dad went to sleep, but shortly he got a phone call from the office. They were calling because there was an emergency and he needs to get as soon at the office. But he is locked inside the house and doesn't know when will the kid return. He must search for a spare key around the house so he could escape and get to the office.
