MYTH #4 - Cell phones can be used to open up locked cars
You've probably heard a lot of urban legends about cell phones. They cause cancer. They crash planes. If you sneeze and hiccup at the same time while talking on one, you die. Like many myths and rumors, many of these stories are based on speculation, misunderstanding of technology, and outright lies. Then again, some of them have facts and experts to support them. Here, Switched.com sorts through the mess and explains some of the most popular rumors and legends. Whether you believe us or not is up to you.
Myth: Broadcasting the sound of a remote keyless entry device over a phone can open up a locked car.
True or false? False. The rumor is that if you have an extra key remote at home, you can call someone and have them hit the open button while you hold your phone up to the lock. Well, those entry systems use radio waves and proximity - think about when you've tried to open your car from too far a distance - and can't be transmitted over a phone. Unfortunately, if you lock your keys in the car, you'll have to get your spare set or AAA to open it for you.
