Where was your friend standing when it worked? I never claimed it didn't work for you, just that it was in no part related to the "cell phone trick" working.

he was in his house... in the basement...which at that distance and in his house his remote does not work.. we were smart enough to test the distance first...then it worked ( and fyi we live in the country areas) which means somewhat larger houses and longer driveways...ie he wasnt fifty feet away behind the fence...he was actuall far enough away and in a confirmed location where the remote doesnt work.

I will test from my house to his next time which is easily 1/4 mile...will that suffice the "BS meter" ??

(note i take no offense in being flagged for BS either that'* why i posted to get past the bs)

Well I don't know what to tell you orty, I don't see how it could have worked, but I'm not going to get into an argument about something I didn't witness or "witness."

Snopes and Mythbusters refute it, I have to side with them.

no argument here...i just wish i knew how contraversial and widespread this debate is...but the fact that it worked convinced my friend... like i said ill retest it over 1/4 mile away from house to house...using the same nextel phones and ill post the results.
given even then noone has to believe me but i wouldnt continue a post if the entire reason i started it was false....so here'* to it working! if not ill recede...surrender what have you
thank * for all the info though

The reason it would not work is because even a tweeter can generally only go to 10,000-50,000hz where as most keyless entry remotes are in the megahertz or 1,000,000hz range I believe.

I could be wrong but I thought that was the reason.

even if the speaker could produce the frequency necessary, I thought digital cell phones use some compression algorithm so they chop the highs and lows off the microphone signal....

Also.. I've seen this via email. It'* in my Free Disney Trip/Free Windows XP list.

Are you saying your friend used his GP transmitter to pop your bonne trunk? If so..that transmitter isn't even coded to your car.

Speakers produce sound waves, whereas radio transmitters (such as keyless entry remotes) produce radio waves. Even if you had a radio transmitter that was operating at 5,000Hz, you wouldn't be able to hear it. Sound waves and radio waves are two entirely different things.

Even if the wireless key fobs produced audio waves (which they don't), a cell phone wouldn't be able to transmit them. Cell phones transmit only audible frequencies of sound waves, usually within the band of about 500Hz to 3400Hz. Modern digital phones compress the sounds using something known as a vocoder to reduce the data rate to something reasonable; the result is a phone that is reasonably good at reproducing human speech and not so good at reproducing other noises. Even if the key fob transmitted sound waves within the cell phone'* audio passband, the vocoder would severely distort the signal.

For the record, it appears that GM keyless remotes operate around 319MHz.

Here'* a pragmatic proof that this won't work: If your keyless entry remote transmitted sound waves at a frequency that a cell phone could transmit, you would certainly be able to hear the transmission. Pick up your key fob and press the buttons. Do you hear anything? No.

QED
