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?
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.
Rubbish.
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.jester
Balls - grow up mate. There is no invisible elctricalicity stuff. It's called witchcraft.... which you clearly know.... so you are a witch.... BURN HIM!!!!

Serious question here for our electrnically gifted friends. Why would you have to modify the car? surly you could, in theory, just change the frequency the phone works on in much the way one changed crystals years ago. Obviously the phone would no longer make calls but could it not in theory be changed as i suggest? Honestly not got a clue, nor do I intend to do anything, just curious. I imagine in practicle terms one needs some fairly clever chip type technology to reprogramme a frequency?

I didn't say you have to modify the car. You have to modify the phone which is near the car, and the phone which is near the keyfob.

If you don't read posts properly this thread will go (even further!) downhill very quickly.

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!'
if you're ever held up at gun point by a robber when you're at a cash point, type in your pin number backwards, the bank will alert the armed response police

yes

They don't but apparently a duress PIN system was considered.

Yes, simply press it against the unlock button on your fob and the car will open like magic. All using a dog whistle!

BUT MY PIN IS A PALINDROMIC NUMBER!!!

That's it, i am screwed. I've only just learnt about this, and it's already ruined for me. I've already been held up at gunpoint 3 times today. Norfolk is dangerous.

The learning remote from a Mitsubishi video recorder could open my mother Renault 18. I had to have the key within 2 inches of the remote to "learn" it but once programmed the remote worked better than the key at unlocking the car.
I think most car fobs are radio now rather than infra red. That trick apparently also worked with laser quest, the guns fire a laser you can see but the signal to from the gun to the receiver on the vest is a narrow infra red beam. Apparently you could teach your guns signal to the programmable remote and then transmit a much wider pattern signal to knock out any vest in line of sight. No idea if it really worked though.

if this worked you could injure someone by calling their phone then quickly chucking your phone in an oven.

Fair point, I did indeed misread it - apologies.
