Unlock car using mobile phone - urban myth?
Discussion
I received this by email today. I might try it out tonight but if anybody has time today I'd be interested to hear if it works. Apologies if it's a repost. The idea is you can call somebody on your mobile, and if they have the keys and blip the remote next to their phone, and you hold your phone near the car door, your car will "hear" the remote and unlock. I doubt it, but...

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 mobile 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 mobile phone!'

Myth. Mobile phones aren't designed to retransmit the frequencies used by remotes.

This one has been going around forever. There is kit out there that you can aquire and use to get keyless entry cars going or to snatch codes from remotes but a mobile is not one of them. However, you can open any car with an old mobile phone.... simply throw it with consdierable force and the window :-P
Put of curiosity - I assume all these remotes work on either IR or radio waves. In theory, could one not convert a phone to generate the right waves as a phone is in essence just a radio of sorts. Forget that to do so would be totally inpracticle and presumably require some rather specialist kit, but why, in theory, could a phone not be made to generate the right wave length?
The mechanism the OP talks about is of course a complete myth.
Having said that, I can lock/unlock my car with my phone, remotely.
It's a BMW with ConnectedDrive, and the BMW android app permits remote locking/unlocking.
I'd show you screencaps, but thumbsnap is having a bit of a morning.

ETA: before someone jumps in calling "bull", the car has a sim in it and the unlock process involves BMW calling the car. It's the same system that permits remote telemetry and/or SOS calls.

They use radio waves.If you could convert BOTH phones as follows then it WOULD work:
Phone at Home:
Needs to be able to receive radio waves at the right frequency, convert them into a data stream which can be sent over the mobile network.
Phone at Car:
Needs to be able to receive data stream from mobile network and reproduce the radio signal at the required frequency.
However that's a hell of a mod, and what you end up with isn't really a phone.

FACT: mobile phones work on invisible electricery
FACT: So do car alarms.
Its obvious that they are the same. I frequently call my wife on my key fob.
