Remote Unlocking Of Car Doors

i got this forwarded email from a friend. not really sure if it's true or not. just in case anyone of you tried this. let me know if it works....

If you lock your keys in the car and the spare keys are at home, call
someone on your cell phone.

Hold your cell phone about a foot from your car door and have
the other person at your home press the unlock button of your key fob
(clicker), holding it near the phone on their end. Your car doors will
unlock. Saves someone from having to drive your keys to you.

Distance is no object you could be hundreds of miles away, and
if you can reach someone who has the other "remote" for your car, you can
unlock the doors (or the trunk)!

Editor's Note * It works fine! We tried it out, and it unlocked
our car over a cell phone!)

Mike's Note *

I locked the car had my youngest daughter call me while I was
far away from the car. I clicked open into th e phone and I could hear
the car doors unlock through her cell phone. My daughter confirmed that
sure enough the doors opened.
