Beach Getaway

Your friend invited you to stay at his beach house for the weekend. While you were relaxing on the porch, you noticed a storm coming in the distance. You tried opening the door only to discover that it was locked, and your friend was taking a nap in his room. After knocking loudly for several minutes, you realized that you were unable to wake him. You know that he has hidden a key somewhere on his porch. Can you find it before the storm comes?
