Use your mobile phone to unlock car

There is an email circulating that states that you can unlock your car door keyless lock with a cell phone. If you lock your keys in your car, you can supposedly call home if you have a spare set of keys. Ask the person who answers to hold your remote key device up to the phone and push the open button. If you hold your mobile phone about a foot from the door, it is supposed to unlock the door even though it is a different kind of frequency. Yet some people swear in works. Others say it’s bunk.

I lost my extra key thingy so I can’t try it myself. If you would care to try it and let me know the results, I would be interested to get to the bottom of this. And, if you have an explanation of how it could possibly work, I would be interested to hear that as well.

Thanks for your help.
