Opening Car Door Using Cell Phone.

[corkscrew]

I found this on the Internet. I can't make it work. Can you?

"Have you locked your keys in the car? Does your car have

remote keyless entry? This may come in handy someday. Good reason to own a

cell phone: If you lock your keys in the car and the spare keys are at

home, call someone at home on their cell phone from your cell phone. Hold

your cell phone about a foot from your car door and have the person at

your home press the unlock button, holding it near the mobile phone on

their end. Your car will unlock. Saves someone from having to drive your

keys to you. Distance is no object. You could be hundreds of miles away,

and if you can reach someone who has the other "remote" for your car, you

can unlock the doors (or the trunk)."

The variation I read used NOKIA What cell phone did you try it on?

I've also heard about it on a talk radio show, they tried it live but no success. They did not try it with the speakerphone on close to the car, that may work.

I've forgotten 99.9% from my Beng electronic engineering, but maybe the .1% is enough to say, no.

1) Digital mobile phones / networks do all sorts to signals. So the signal coming out is nothing like the one going in. (frequency clipping, data compression, etc)

2) What kind of signal does the remotes transmit? I doubt if it's one that is able to travel down any kind of phone line, even without the above point. (can't be in the "visible" frequency range anyways)

It's possible, maybe, that a remote that uses a very stable and uncorruptable waveform, or more likely they car receiving unit has a wide ...

.. no, I'm trying too hard. It's not possible. On an exceptional analogue line, remotely possible. On a digital network, no.

(Of course, the fact that I don't really remember what I'm talking about may inhibit the accuracy of this post.)

No will not work, regardless of telephone brand.

Entirely different frequency required.

Very clever and funny!

[Crossy]

I can think of no plausible mechanism by which this could work, be the remote Infra-red (very-rare), ultrasonic (rare) or RF (the common one), the phone and network is simply not designed to transmit these signals, in fact it is designed to specifically reject such signals to prevent interference.

Internet bunk.

Agreed. The only signal passed that way is audio frequency, and the remotes don't work in that range. Plus with rolling locks, the remote would need to be near it to resynchronize.

In the past when Ive needed to unlock a car that Ive left my key's in I simply use the tv remote. press (4) if you have 4 door or (2) if it's a cab.

Neither solution works, alarm goes off and won't stop and car won't start without remote to turn off alarm. I had a problem when battery to remote went dead at shopping center and no one had replacement batteries including dealer. Extra remote was 660 K away.
