i just did it, i have no reason to BS, and i did it with AT&T digital phones... i can scare the crap outta a lot of my friends... lol.. >=]

 

i read this post earlier today and i tried it.. i have a 2002 civic and it worked i have a t mobile and my friend had a cingular phone and he did it from inside a building and i walked all the way out side right next to my car... worked!

 

i just thought of something weird. While my keys are in the ignition or just laying around in my car, my car will not auto lock the doors. I waited a few minutes to see if my doors would auto lock and i wouldnt. So i dont see how people can lock themselves out of their car.

Weird.....

 

I was about to call BS, but then I thought about it. It could happen, especially if there is no filter limiting frequency on the receiver or transmitter. I say no go for CDMA(Verizon, Sprint...) or landline though. Then again I got B's and C's in my engineering classes. LOL

 

how can you lock yourself outa the car when using a keyless entry method? I have locked myself outa my '93 suburban a bunch of times.... but thats me hitting the inside locks while leaving the keys in the car. I dont eevn know which way on the locks unlocks the doors on our cars half the time and have to lock the doors and then unlock because i never use the button lol. My biggest problem is NOT locking my doors haha. I wish there was something in my phone where i could call a number and it would lock my car... NOW THAT would be something to post about

Hey Godzilla, how far away was your friend from the car? Some have hinted its just extending the signal through the antennas of the cellphone. Were you guys over 5 miles away? Now that would be interesting.

What a bunch of BS. Your cell phone emits sound frequencies from a speaker (~40 to 15000 Hz probably, and very poorly at that), not RF, during a phone call. You can't "call your car to unlock". The RF signals between the cell phone and the cell tower are a different band than the one keyless remotes use, and the signal patterns are different.

Who thinks of this crap and spreads it across the internet?

Oh and BTW, this is a repost from a few days ago! Please let's stop posting to this thread so it dies before innocent people are hurt [img]/w3timages/icons/smile.gif[/img]

Thanks for being the repost police but this is the same thread that I started a few days ago that you're talking about. Look at the date. You're calling BS but at least 4-5 people have gotten it to work.

Lets see here....

Cell phones use small mics to turn analog voice (sound) into digital data. The frequency of a persons voice resonates the mic, causing the voltage across the mic to change. This analog signal is then converted to a digital data stream that is transmitted back to a cellular tower.

A car RF remote is a humanly-undetectible digital signal that is pulse modulated at a predeterimed frequency (around 433hz for most modern day car alarms, but maybe lower for our stock transmitters with terrible range). Pulse modulation works by varying the time between pulses.

To sum up all the techical stuff, unless the microphone (which senses changes in air pressure) on the cellphone is senstive enough to pick up RF waves there would be no other way for this to work. And, if the microphone is capable of 'hearing' RF signals there would be NO way you could hold a conversation on a cell phone - there are 1000s of RF signals swimming around all the time - radio, tv, GPS, even other cell phones!

I would say that for the people who have got it to work that most likely you were close enough to the car for it to somehow receive the signal, and it is possible that somehow the cellphone antenna helped boost the signal, but I find that too to be a little far fetched, as cell phone antennas are optimized for a completely different frequency then our cars!

OK, I see that this thread was before the other one. Still think it's BS though![img]/w3timages/icons/smile.gif[/img]

4-5 people have SAID they got it to work. There are always folks that are willing and ready to promote a hoax. Always have been, always will be. It's a kick for them, I guess. They probably like watching "Craky Yankers" too.

 

I would not believe anything from anyone who said it worked for them.

Or from anyone who believe it works because they read it on the internet.

There is no way it will work. Anyone who said they got it working is pulling your leg or adding to the myth.

Telephone network are specifically designed to be band limited so they can squeeze in as many voice channels possible. I am sure the RF freq on the remote is not within audible band to human so even if microphone picked it up the lowpass/bandpass filter on the network will eliminate it.

Now someone said the signal get imbedded into cell signal and rebroadcast it to the car? There is no way you can do it on a digital phone. Any extra signals or thermal noise besides the ones from your phone will be treated as noise and disregarded. You can only jammed your current signal but you won't be piggy back.

Unless your remote created a jamming that creates an on/off signal then it might be possible but the chances are very small. Unless someone can provided a scientific reasoning or show me in person I won't believe it.

ok... for all of you who call bogus...

this is EXACTLY what happend with me... no i wasnt 5 miles away, cuz i am way too lazy to coordinate that kind of experiment....

i gave my little brother my phone (AT&T digital NOT GSM)... and i took my moms phone (same phone)... i called him and got him on the line... he was as far as he could go inside my house, FROM the garage... i told him to first try locking the door (so i can hear the beep), while aiming it at the phone, as i aimed my phone at my driver's side door... it honked... then i told him to hang up
and try locking again.... no dice...

so... if you call BS... i call BS...on your BS... but lets not argue over this... cuz really its not that important [except if you came up with ideas to steal your friends cars and /or belongings like i have.... hahaha jk!]
