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.

hehehe i would,nt think so bro the fob opens the car by the sensor chip in the fob... not by the sound of the fob down i phone.....
Posted by Boysie99
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.

Fair enough guys, myth BUSTED!
Posted by Daedalus85
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.

Didnt Jeremy Clarkson do that on TG once?

i heard of it a while ago. my operator(Orange Dominicana) used to offer this service. lately, they have stopped offering it(i think).
Posted by Daedalus85
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

the car might nt get unlocked by som1 at home pressing the unlock button of spare key
but i have indeed seen a system where u can use a cell phone itself to unlock the car, lock the car even start the car
u have to put an external device in the car which picks up DTMF signals frm the cell phone keypad. u can also program tht box for different combinations
e.g. u can program the box so tht if sum1 presses 123 , unlock the car..
i have seen a system like this actually work. it was a final semester project for a group of electrical engineering students.

I guess it could seem to work if you're parked outside your own house.........

Hahahahaha this the funniest myth ive heard lol its a joke man how on earth can that possibly happen maybe inventors had made a car that can do that or even a phone or the fob lol (and wooohooo ive got my tenth post)

Make a small box using aluminium kitchen paper. Put the car key inside the box and press the open door button. Quickly take your hand out of the box and close it, before the door opening signals get out of the box. Now, you have always with you a box containing the door open signals. Aluminium keeps it inside. When you loose the key or forget them inside the car, just open the box carefully near the car door and it will open.

@jaja
Hahaha, Does it really work ??
Posted by strizlow800
This cant work imo. No way
Posted by max_wedge
Yes it works, but you have to coat the aluminium paper in kryptonite first...
Posted by Muhammad-Oli
Oh yeah I've heard about this. I've just bought some kryptonite to give it a go myself...
Posted by max_wedge
yep, works a treat, not a good technique for Clark Kent to dabble with tho...
Posted by st0nedpengui
You used to be able to do it with watches that had programmable IR for switching TV channels and stuff, I doubt it works anymore though.

had a buddy set up a wifi reciever and his cell to lock/unlock/windows up/down etc, pretty neat he spent quite a bit of time of getting it to work, i guess the part that was difficult was getting the wifi receiver to actually correspond with the install alarm system, but just shows anything is possible
Posted by A L 3 X
doesn't work, heard it a few times on diff car forums, its just a myth apprently....I havent read the other posts so dont flame me if this has been said
Posted by catalinux
Interferences happen and have various results. Absolutely every time I forgot my cell inside the car, receiving a call would trigger the alarm.
Unlocking never happened though, so don't count on this method to unlock a car, yours or not.
Posted by badassmam
Aston Martin sell a watch that either unlocks and/or starts the DB9 up. Maybe you should check that out, that may help or not.
