Not supposed to be able to if they're in the ignition but in case you do...
<edit> DON'T try this unless you have a spare KEY with you!
If your spare remote that came with the car is with someone you can call just call them from your cell phone, hold your cell phone up to your car door and get them to press the unlock button on the remote they have. It will unlock your door, a-la OnStar. Sorry if this is old news, just heard about it the other week and got around to trying it today (but only as a test hah). It worked. Freaky! It supposedly works on any car 2000 model year and above but may work on others as well.

WHAT THE hell...does the remote work on a frequency u can't hear or something? and like the cellphones can pick up this frequency and send it over the network and then come out the other end? and reach the car? or something like that? Someone explain how this technically works cuz this is damn interesting.
Wow! It's the coolest thing I've heard. I'll try it. Although if it works, I can't say I am too surprised. When I was studying DSP at school, I touched on the subject of coded transmission. I vaguely remember a technique in which basically the transmitter will send a predetermined long sequence of audio signals out. The amplitude can be very small, definitely not audible. But when the receiver, which is much more sensitive than the human ear, hears that exact sequence that it is expecting, it determines that it is impossible for that to be noise. So it will accept that and open the door.
Phone is nothing but a device to transmitt audio signals. If the signal frequency is not filtered out by the phone, then there is no reason why the receiver in the car won't here it.
Can anyone in the DSP area, or better yet, anyone who had worked on remote controls confirm that? Maybe a little more detail?

I can understand the phone transmitting the audio signal...but I don't understand how the car "recieves" this signal though the phone. Doesn't it require the car to have a mic somewhere located near the door? and a mic that needs to be able to withstand weather and car washes? If the frequency was high enough then maybe I would believe it resonated through the panels of the door or something but I doubt that hypothesis.
Yea I kinda think that it might not work...or if it does, it depends on the phone. Some phones are designed to remove certain freqs out of the range of freqs it picks up from the mic to help reduce backround noise. So I'm guessing if ur phone has nosie cancelling or some type of backround noise reduction it might not work.
We just tried this at work, the guy with the remote was far enough away and on the other side of a building at least a block away, and it worked! We tried just the remote first without calling and it was to far away to work, then he called me and held the remote up to the phone while I held my phone up to the door and after a few seconds the door unlocked! [clapper] Next I think I will call the wife at home and see what happens...
We did this with my wife's FX35... the wife wanted my G to go play today...[8D]

LOL! yeah it was weird when I did it. I shoulda posted this in the general area so the sedan people would see it too...ah they're checking us out too []
ck I held the cellphone up to the door handle area and didn't have it on speaker, though I suppose sometimes speaker mode might help where the handset volume was set low maybe.

If you are just a little to far from you car hold the remote tight against your chin and press the button. This works, I know, I do it all the time.
As far as the telephone trick, think about this. A remote works somewhere in the 400Mhz+ range, do you think a cell phone is designed to operate that high.
A telephone works in the 300 Hz to 3400 Hz range.
