Have you locked your keys in the car? Does you car have remote keys?

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' date=' 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). [/quote']

Has anyone tried this? is it confirmed, or busted?

Nope, false.

Remotes work on 433 mHz, mobiles on 900,1800 and 2100 Mhz.

I'll stick my neck on the line and say it's complete rubbish. HTH.

apparently mine makes calls but i don't get a chance as i am too buys using the net, satnav, sending texts and taking pictures.

I see, I thought that might be the case. Sounds good though.

if it was true just think what fun you could have with a tanoy system.

Total tosh. That's up there with Tartan paint.

BTW GSM mobiles work on many frequencies around 850, 900, 1800 and 1900 mhz.

Doesn't it mean that it will carry the radio wave through the mic and out the speaker at the other end rather than piggybacking the phone signal?

Interesting. Schern, just how are you modulating a 430MHz or so radio signal onto a typically about 200 to 4_000 Hz audio signal?

I bet someone's done it on a Paxo or Corsa though as a 'mod'!

although i doubt it actually works, but your stating the frequencies the phones transmit on, i dont think that has anything to do with the theory. i think the idea is the remote fob sends a signal out which the phone somehow picks up and it is then repeated out of the other handset so that the car can pick up the signal and unlock.

it dosent matter the phone sends the signal by GSM, its the fact the actual mobile phone handset is able to repeat the remote fobs transmission (or not as i suspect the case maybe)

but lets face it all you really have to do is stick it to your head to get it to reach that little bit further. so if you get loads of people banging their heads together you could send the signal MILES!!!

But it's completely the wrong signal for the carrier - like sending a train down a fibre optic cable, just can't work.

Yup utter crap.

Although, you can increase the range 3x by holding to your head, as proved on TG a few years back

Why, other than sheer laziness when I've forgotten to lock the car, would I want a remote with a range of 300 feet?

Pretty pointless really, my range was so far once that when i got to the car it locked itself again (the head trick im on about)

Exactly; it's borderline whether I can get to the car before it relocks as it is.
