You may have heard rumors of how you can open your locked car door in a pinch using nothing more than a tennis ball. In this video, someone poked a hole in a tennis ball, lined up the hole in the ball with the key-hole of a car, pressed really hard, and the door unlocked. In this video, they decided to put that tennis ball technique to the test.

This can save you a locksmith charge if you lock yourself out of your car.  I just purchased a new car (as a result of my recent car accident) that has an absolutely amazing feature.  If I ever lock myself out, all  I have to do is call an 800 number and they will send a signal to the car that will automatically unlock it.

Amazing
