Please read this you will be amazed its unbelievable

[ScottyBoy]

I heard this on the radio today that a guy by mistake locked his keys in his car so he phoned his home and got the person to fetch the spare key fob, point it towards the mobile phone and press unlock, as they did this he put his mobile close to his car and hey presto it unlocked. I know what your thinking its not possible but i tried it and to my amazement it worked. Please go and try it and be amazed.

I'll have a go, but if I look silly, they'll be trouble

Dont bother Dave

Not saying i don't believe you but,,,,, is this a wind up?




Going to try it later though


Thinking about it, aren't key fobs radio waves and mob to mob's would be sound waves?

[ScottyBoy]

This wasnt put on as a wind up honest, ive looked on the web and read a few things about it and it seems like its a mixed bag as to whether it works or not. I tried it again with 2 Nokias this time and it froze my keyless entry and i had to use the key to open my car but after i locked it again the fob worked fine. The first time i tried it i used a samsung e900 and a sony w850i from about 40ft in my kitchen, i dunno maybe i was duped into thinking it worked but really my fob can work from that distance. Let me know if you try it and it works as i feel a bit silly now.

You cant be serious do you know how they work, they dont work on an audible singnal - what are you on?

Well obviously Firkin not mate ay, otherwise i wouldnt of posted it would i, do you know how they work smart arse maybe you could explain to me instead of making little swipes after all thats what i thought the forum was about. What am i on, what you insinuating im on drugs, you want to choose your words more carefully sunshine.

Now now, Scotty and MCB, play nicely! Thats the one thing I hate about emails,forums and text messages, you can't pick up someones banter/sense of humour

If we all get on the same wave length we can probably open each others cars just by thought power

- My above comment was said totally in jest -

[SimonS4MTM]

DrAl where are you.

Key fobs work on radio waves that travel through the air, they cannot be picked up by a mobile phone and converted into a digital signal to be played back through a speaker.

[david7m]

Maybe the aerial on the phone/your body acts as an aerial and sends the signal further.......A bit like the old trick if you are too far from your car, holding the key fob against your chin makes the signal travel further (I personally like to do this, but raise one leg and put my left index finger under my nose!)

They either use infra-red or radio signals....neither of which can be transmitted between 2 mobile phones. Never going to work.....

This is bull$hit! I've worked in a technical remit for a mobile operator for 17 years and the frequency band allocated to remotes in the UK (433Mhz) is nowehere near the operating frequencies of mobile networks in the UK (900Mhz & 1800Mhz) or even abroad, which means the handset is not capable of transmitting the signal in the first place.

Here is an extract from the Radio Agency;
In 1993 a European frequency of 433.92 MHz for radio car keys was allocated by the European Radio Committee (ERC); this became European Law in 1995. The same frequency was already legally allocated to other users: the primary UK user being the Ministry of Defence, with secondary users including amateur radio operators and traffic information systems. Some private and public access mobile radio networks operate close to the 433MHz band. These stronger sources of radio transmissions can sometimes block the signal from a radio activated key.

[shineydave]

i agree, total bollocks, although i actually did try it.

by the way scottyboy, my wife is now convinced i've totally lost the plot after standing by the car in the rain shouting into the mobile telling her to press it harder, lol

Definitely not insinuating you were on drugs or anything similar, just an expression did not realise it would upset you so much. Honestly thought this was a wind up being taken a little to far as people were being sent on a fools errand by you!

I think Nige RS4 has this one bagged:

Enough said?
