Car Cell Phone

well my cousin sent me this e-mail, it was pretty intersting about cell phones. now im not sure if this works and i wanna try but let me see hat u guys think before i make a fool out of myself Subject: Have you locked your keys in the car? Does you car have remote keys?* >This may come in handy someday. Good reason to own a cell phone: >If you lock your keys in the car and the spare keys are at home, call >someone at home on their cell phone from your cell phone. >Hold your cell phone about a foot from your car door and have the person >at your home press the unlock button, holding it near the mobile phone on >their end. Your car 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!"*
