Honda Car Forum

Hondarinos,

I received this forwarded email, pasted below. Is it possible? I'll try it
eventually but is this common knowledge or what? My first instinct is BS,
but admittedly I'll try it later this evening and look around and make sure
nobody is watching, HAHAHA.

This only applies to cars that can be unlocked by that remote button on your
key ring. Should you lock your keys in the car and the spare keys are home,
here's your answer to the problem!

If some one has access to the spare remote at your home, call them on
your cell phone (or borrow one from someone if the cell phone is locked in
the car too!)

Hold your (or anyone's) cell phone about a foot from your car door and have
the other person at your home press the unlock button, holding it near the
phone.

Your car will unlock. And it works! Knowing this 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, or have the
"horn" signal go off, or whatever!)

---------------------------------------------------------------------

OMG... how stupid are you.

The typical remotes today are radio frequency operated so no this doesn't
work. However, with bluetooth technology someday there will probably be
that option but it will work a little differently. They already have the
ability to have your car unlocked via satellite, i.e. ONSTAR.

The code from the remote is modulated over a radio frequency signal. With any
modulations, there are sidebands. If the cell phone somehow pickup the sideband
of the code and transmit it to the other cell phone, and that the other cell
phone somehow send out sideband that coincide with the remote receiver, it could
work.

Even if there was any energy left at frequencies low enough the get into
the voice band, the digital voice coder would mutilate it to a point of
being completely unrecognizable. Even with an old analog cellophane, it
would not work. Remotes usually operate around 400 MHz, the attenuation
at 10 kHz is next to infinite.

If your remote worked on audio signals, like DTMF, there would be a
different story.

the only way I see that happening is if you had a device which converted
radio frequency waves into something that is able to be transmitted via
sound and then it was rectified, for lack of a better term, on the other end
and reproduced a radio frequency. The frequency which the remotes operate
at are not within the range of a cell phone speaker. A cell phone speaker
only goes up so high and it isn't that clear anyway. You would need
something that produced the right frequency that matched with your
programmed remote.

Sounds like an urban legend, not that this isn't possible to do....you
would need equipment specifically designed to do it. The cellphone is
going to reject anything modulated at the wrong freq., not to mention
the error checking in the data stream will reject it regardless.
