Emergency remote car unlocking method

[Hitcher]

Has anyone asked Snopes about this yet? Sounds decidedly dodgy to me. Particularly the "given" that you know somebody with exactly the same locks as yours...

Yep, False. Read it here.
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.)

We don't know whether whoever created this message was deliberately joking or earnestly mistaken, but the vision of stranded motorists vainly holding cell phones up to their cars in the hopes of unlocking them is an amusing one. One might as well suggest that a spare piano key could be used to gain entry to a locked automobile.

(More than a few people have inadvertently fooled themselves into believing the cell phone method of unlocking car doors actually works because they tried it and achieved the desired results — not realizing their cars were still within range of their keyless remote devices, and the signals that unlocked the doors were transmitted the usual way [i.e., through the air], not via cellular phone connections.)

wotuttercrap!!!!!! unless youve got a really nasty, cheap DTMF (dual tone multiple frquency) alarm.

Remember on Top Gear they did the thing with remote not working cos too far away, and then putting against head and it unlocked. I've tried that one and it works. Maybe your brain waves unscramble signals sent over the phone? Can anyone else please try it cos I need to know if it works!

The cavity, your mouth acts as a passive amplifier in that the remote controls radio waves amplitude is slightly increased, in addition (thank Farraday for this) directional amplification is achieved thanks by the bones in your head (a bit like a directional antenna). So in other words you should try and face your car when you do this as youll get a more directional beam. If you turn away of to the sied, it may still work thanks to the RF "lobe", bu the main bean is pretty much straight in front of you.

The actual power increase (dBm or mV) is very small, but it can help just enough when your batteries on your remote are beginning to fail.

which is a tek-nickle way of saying what I said (almost).... fuck, maybe I'm not completely stupid after all!!!!

Yep, although I admit to not reading you post before I posted as I just though,"wot a load of bollox", upon reading the orignal thread. So yes, you're 99% right, apart from the brain electricity stuff.

I need to be careful when I start talking technical and spouting off cos the last time I did that I got into a lot of trouble as somebody thought I was being condescending and took a fence.

I wasn't - Im just more intelligent than everyone else here.

It sounds like this works with non-rolling code remotes only. Pretty scarce these days.

[F5 Dave]

That’s not wot he said at all, rolling code is irrelevant (although highly desirable). The point is the cellphone isn’t retransmitting the signal in any way, all it would be passing is any audio noise (none anyway) through the speaker, which ain’t going to do jack.

More amusing is some early nasty alarms used infrared. Some guy at my old work bought an import with it.

Some clown bought a learning TV remote & gained access. Kept changing subtle things, moving the seat position, next day turn the radio way up, leaving chocolate wrappers. Had him flummoxed for days.

maybe i've just got a REALLY strong remote.....

what a cool idea!!!


hey BIff, you aint smarter... just I cant be fucked

Put my fence back where it was before my dog gets out!!!!

[jase]

Tried it, Didn't work.....was worth a try.

I'll bet you're modest, charming, handsome, rich, independent, and caring too.

I think he said that in a poem somewhere.....

[soundbeltfarm]

just tried it and it didnt work.
wouldve looked like a crim to people going past as i walked around the car holding the phone right up to it.

[Skunk]

Oh for crying out loud. Stop trying this people! Read the posts!
You're starting to look as stupid as I act.

Yep, It don't work... Read it here.
