I got this in an e-mail from a friend. It works....I did it! I don't know about hundreds of miles, but from a good distance..it works. Cool stuff to know!

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!).
