Lock out at House

You wake up in the morning, do your routine workout, take a quick shower, dress up, and prepare to go to work. On reaching the door, you find out that you don’t have your keys. Also you have been locked in or lock out!

In a worse scenario, you are driving in a dark road in the middle of a place which is known for criminal activities, or one that is inhabited by wild animals. You decide to get some fresh air, before proceeding with your journey. But as soon as you close the door of your car, you realize you left the keys inside. The only option you have is to break the window, which is the last thing you want to do.
