Executive Summary:
You own a car with a Remote Keyless Entry (RKE) system. You lock your RKE key fob in the car, or lose it somehow. You use your cellphone to call your spouse who has the backup key fob. The spouse holds the fob to their cell phone while you hold your cell phone next to the car. Spouse clicks "unlock" on the fob, the signal is transmitted somehow through the cell phone transmission, and your car unlocks.
Does this really work? If so, HOW does it work?
I\'ve never heard of this until today, and I instinctively disbelieve it because it doesn\'t make sense based on my understanding of RF keyless entry systems and cell phones. I\'m willing to believe, but I need to see it for myself, or hear a reasonable theory for how it works.
There seem to be a few people out there who claim that it works, though they don\'t understand why. One of my coworkers says she knows some people who use it all the time. I naturally distrust third hand accounts like that, but I\'d like to find some better evidence that it DOESN\'T work before I call them liars.
Have any of you heard of this before? Maybe you\'ve actually tried it? Here are a couple more interesting links:
