Mobile Phone Keys

[Jordan]

My mother sent me a forward today which had five tips for "things you didn't know" about cell phones. This was #2. I have to say I think this one is a hoax:

Does your car have remote keyless entry? 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!"

I heard someone at my work actually did this and it did work.

However, I'm quite old school myself, so I doubt my Chevy pickup would work in this scenario since my locks are the old "turn the key to open" kind.

Have you ever seen a manual locking door Jordan? They're quite rare nowadays.

hehe

Yeah John, I saw them for the first time in your Truck the other day!

Yeah I read that sometime ago... I never tried it. But maybe it might work....

Hate to break it to you, but your key is a 128-bit scrambled RIF, not a sound wave /=
This wouldn't work by its very principle. A normal phone cannot transmit this type of wave without modification.
