Default LOCKED OUT??? i have a new should be sticky post!!!

since i think this claim needs good explanation im going to do the long approach.
I work at a convenience store/gas station/pizza place/restuarant/farmers market/ice cream place (yes all one owner all in three buildings!) And because of the gas station thing ppl sometimes lock their keys in their cars and because we sell the thing metal strips for getting through window seals and unlocking doors i usually am the one helping the customer. (ive unlocked about 10-12 cars now) not too hard a job but handy b/c im skilled at it now.

Anyway the other day when i was unlocking a customer approached the person i was doing the unlocking for and asked if he had a keyless entry remote and someone he could call at home. His claim was that if you hold your cell phone pointed at your car (close up) and the person on the other end of the line clicks your keyfob BAM! you can unlock your doors. Now this does make sense as it is just a sound frequency then transport it over the phone but the average person would think this is absurd and the phone waves could distort the frequency that we as human beings obviously can't hear.

So my friend and i finally tried it tonight, using a two nextel'* we couldnt get it to work via two-way, so i called him....still nothing, so in a last ditch effort i put him on speakerphone and pointed my phone at the window. then..... BING! he opened the trunk!

Like i explained above the science is simple but just coming up with that is just not the first conclusion one comes up with when they lock their friggin' keys in the car. So if you have two remotes keep one at home or with someone you can always call because you'll never have to break into your car again! (dont have two remotes? ebay it the reprogram...tech info saved my 60 bucks that way)

Anyway i thought that was sweet and havent seen it on here yet so i thought i'd save some ppl broken windows keys and patience, by telling them just to make a phone call.

Wierd, I think this has something to do with the cell phone and not the sound?

Send it in to myth busters

I dunno, I'm skeptical, unless Bonne'* use something other than the standard remote keyless entry system. Sounds like BS to me. Read this:

Keyless entry remotes do NOT use audible frequencies. Nor are modern cellphones cabable of transmitting sound outside the audible range.

No sticky, BS. If it truly worked, it was a fluke from the RF 'noise' the cellphone produced. Which I doubt also.

Additional information from the Snopes article for those that don't have the understanding of our systems that some of us do, or don't believe us:

Quote:
Relaying remote entry system signals via telephone might work if the signals were sound-based, but they're not. An RKE system transmits an encrypted data stream to a receiver inside the automobile via an RF (radio frequency) signal, a signal that can't be effectively relayed via cell phone. (In any event, RKE systems and cell phones typically operate on completely different frequencies; the former in the 300 MHz range and the latter in the 800 MHz range.

I think the most likely explanation for why it worked is because his friend was probably just within range of the car or something, you know how one day the transmitter will have like freaky-good range, and other days you have to be practically on top of the car to get it to go off.

i read snopes...i agree, but the fact is that it did work...he has a gp but i figured they would be much alike....nonetheless there is no bs in my findings with my friend. maybe the guy that told me about it was full of it but my test results made me a believer....has a bonnie man tried this?? even if it doesnt work with all cars if it works for us that'* good enough for me...i guess i dont need a sticky but an interesting subject none-the-less
