Just about all of us have locked our keys in our car at one time or another. Or maybe your kids or your significant other has done it for you. Either way, once it happens, it's definitely the kind of thing that can ruin your day.
Even if you have a set of spare keys, stuff happens, and you may find yourself in a situation where you don't have your spare keys handy. When that happens, what are you going to do? Call your family and have them make fun of you? Pay a bunch of money to a locksmith?
If you don't feel like going through that kind of hassle, why not try this method? It works like a dream, provided you have a car with exposed locks on top of the door. Cars with locks on the inside panel of the door won't work with this trick.
String that is the length of your car door, plus one foot (the one in the video is two meters, roughly 6.5 feet).
