Wow. How wrong... yes a cell phone is a radio transmitter. But For a radio signal to be retransmitted you need a repeater. A cell tower is a kind of repeater but the cell phone itself is not. So there is NO WAY for a RADIO signal to be retransmitted by your cell phone. For that to happen your phone needs to recieve the radio signal from the remote. Many of the remotes I've seen are in the 450Mhz range. I don't know what frequency BMW uses in the FOBs but if someone can read the FCC ID on the back of theirs I can find out. So for the cell to even be capable to resending the signal it needs to listen on the FOBs frequency (lets say 450Mhz). We know that phones operate (in most places) in the 800Mhz-900Mhz/1800Mhz/1900Mhz ranges. Well outside the range of the cell phone. And then the other phone would need to be able to recreate the signal on the same frequency. The number of channels used and the fact that it's duplex or simplex has nothing to do with it. For the record... I have 'walkie-talkie's' that transmit at 5w and the wattage has little to do with how far the signal will travel. CB's in the US operate at 4w and in AU it's ~40w for their UHF CB. How far a radio transmits depends on the frequency used and the height and type of antenna used.

IT WORKS!!!!!!
I just tried it on my wife's X3. I point the phone to the car, and I pressed my unlock button and POW!
it opened... oh, did i mentioned that I was pressing the buttons on my keys while pointing my cellphone to the car 4 ft away?
But, it worked....

This is strange because I was telling a friend of mine about this just this weekend. I swear this works on my Honda Civic (now my wife's car :-) but I have never tried this on my e60. I should give it a go sometimes and see. BTW this doesn't work on all cars because it didn't on my friends Ford Focus.
Man talk about disparity in your car household ;-)

Dawyeah, thanks for being the guinea on this one, but what about an E60, anyone up for it?
It looks as if for some cars yes and some no. I wonder if the type of cell phone makes a difference?

Anyway I can confirm that this trick does work on some cars. As mentioned it worked on my Honda and a mate's Mazda. But not on a Ford and I've yet to try it on my e60.
