On a radio talk show this morning, one of the DJs had accidentally locked the car with the keys still in the ignition. A listener called in, claiming that he'd gotten out of a similar jam by calling home and having his wife hold the spare "clicker" up to the phone and pressing "unlock" while he held his cell phone a foot from his locked car. A "poor man's onStar." The guy sounded legit, whatever that's worth.

Would this really work?

 

Anyone try this yet?

 

I have heard of this too. I cant remember if it works or not, but if I had to guess my answer would be NO.

 

Snopes says it's BS.

The fob works on a radio frequency, phone is sound, the fob is 433 MHz when you press the button the fob would send a data packet to the receiver in the car with a serialized code for your car. If this would work over the phone we would not need dial up because we could call our wi-fi. Dial up is tonal, wi-fi is frequency.

 

^ urm dial up is frequency based as well ... the thing is that it operates on one frequency, a single band, that is why the speed is so slow ... by wi-fi i assume you mean broadband, fast connections ? those operate the same as dial up but on multiple frequencies at the same time, thus giving it extra speed ... old school copper telephone lines were not meant to carry multiple signals frequencies all at the same time and often ended up with too much data error ...

but anyway, back to the subject ... yes total BS ... radio frequency will not carry over a telephone receiver ...

 

I'd seen this on youtube and wondered if it really worked. From the video it appeared that it did but you can't believe everything you see on youtube.

 

I think you missed what I was trying to say, but simply put both are frequency based signals one is sound generated and one is radio generated. Neither are "Directly" compatible. If the car lock was tone based the phone solution "might" work, thing is in the end we both agree!

 

Back in the '60's , we had a remote control TV. The remote had only two buttons-two HUGE buttons-and no batteries.

The buttons (one for channel, the other for "on-quiet-medium-loud-off") were about an inch tall . You had to squeeze like hell, and an air pump made a "whoosh" . We figured maybe it contained a reed like a little harmonica which put out a note in the "dogs only" audio band. If you jingled a set of car keys just right, it would change the channel.

If I'da had a cell phone in 1967, I probably could've switched from "Bewitched" to "Get Smart" from across town.

 

simply put the phone is designed to reproduce only voice audio frequencies and the fob is far beyond the audio spectrum so obviously this will not work.
