Someone told me the other day that if you lock your keys in the car and the spare keys are at home, call someone at home on their mobile phone from your mobile. Hold your mobile about a foot from your car door and have the person at your home press the unlock button on the spare fob, holding it near the mobile phone on their end. Your car should unlock.
Is this possible and does anyone no how its possible?
I would try this myself but have no spare fob.

Thanx for your reply Shotgun, but doesn't the fob transmit a radio frequency to the car? And then carried from the phone?

Hahaha! 
I can think of sooooo many reasons why this wouldn't work, but you've got me intrigued.  I'm gonna try this tomorrow (its just turned midnight here and I'm off to bed).
I'll be amazed if it works!

Heard it, seems plausible, tried it, it doesn't work.
However, standing a good (viewable) distance from it and holding it to your head and pressing it works, it turns you into a human antenna for the signal to boost through.

Haha, I don't see how the radio signal can get into the phone and be transmitted through a network to another phone which then transmits it out again to unlock the car. After all, the phone is only picking up sound, its not looking for radio signals.

True, but from what I gather, it's still transmitting and recieving radio waves that are somewhat close to the ones a remote car unlocking system uses, therefore if there nearby, the phone can pick them up as 'interfereance' from another device and transmit them too.

NO,
Cars with remote keyless entry (RKE) systems cannot be unlocked by relaying a key fob transmitter signal via a cellular telephone. RKE systems and cell phones utilize different types of signals and transmit them at different frequencies.

Thanks Bulti48, I think we can draw a line under this myth. |

Lol, I doubt an operator would offer something like that.
And yes, he did, but I've heard it before/tried it since and it does work.

Any car locking system that was to use sounds would be just as secure as any other system, and imho there have been car alarm systems design using sound frequencies, but the majority use RF.
My Peugeot 405 uses infrared. Theoretically, it may be possible to open my car remotely by having someone call me by video call and pointing the ir beam of a spare fob at their videocall camera, then I would point my screen at the ir receiver. Digicams work in the infrared frequency (which is invisible to the human eye).
However there may be too much attenuation of the ir signal by the time it get's to the receiver to work effectively.

Well, apparently it's a hoax that's been around since 2005. Check out this link: http://www.trendmicro.com/vin[....]+by+Phone%22+Email+Hoax&Page=1 |
