There are many frustrations that we may deal with on a day-to-day basis and at times, we may have something unusual happen that just seems to send us over the edge. In most cases, it is a frustration that we would like to live without and when it happens, we automatically think about how strange it is that we are in such a position.

One of those problems is when we lock our keys in the car. The first thing that we do is try the door, and then we check our pockets to make sure that we didn’t bring the extra set along with us. Finally, you look in through the window and stare at the keys that seem to be mocking you from the other side of the glass. There is usually a good reason why we did it, but that doesn’t lessen the frustration of the fact that it happened.

If you have found yourself in this situation, there is hope. In fact, there is an ingenious trick that can open your car door, even if it is locked from the outside. The only thing you will need is a tennis ball with a hole in it. When you use it in the way that is shown in this video, it will actually force the lock open from the outside using nothing but air. It’s a rather ingenious method, but it is one that can save you a lot of frustration and perhaps even the charge of having somebody come out to open your car for you.

Of course, it will be necessary to carry a tennis ball but many people will do so, just for the convenience of having their car door opened. You can even tape the tennis ball under the bumper in case of an emergency.
