A friend sent me this email it seems interesting but I doubt it will work, If anyone tries it post the resutls, it will be interesting... "If you lock your keys in the car and the spare keys are home, call someone at home on your cell phone and ask them to get your car keys. Hold your cell phone about a foot from your car door and have the other person at home press the unlock button on your keys while holding it near
the phone on their end. Your car will unlock. It will save 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 omeone who has the "remote" for your car, you will he able to unlock the doors (or the trunk this way!)"
