Received email that if your car door is locked and you lose (misplace) your keys and remote, call home via cell phone, have someone push the "unlock" on the other remote near a phone while you hold the cell phone next to the car. This is suppose to unlock the door, however isn't there a difference with radio waves and sound waves?
...Oh and one more thing, that WHOLE Roswell incident was like a TOTAL conspiracy man....the crash was caused by the signal from a weather baloon being relayed via the Citezen Band network which caused an overload in the spaceships reactor drive unit, which shut down, thus causing the crash...
I want to throw out one more thought...I tested this with several cars and all with the same results, that is, whenever the other cell phone was way outside the normal key fob's range (30 miles) it never worked. However, we were able to get the key fobs to work at what appeared to be an extended range. For example, my car is iffy at ~50 feet (my battery is almost dead) but at about 100 yards I held it to my phone and "beep-beep". It was even pretty repeatable. I held it away from my cell, nothing, moved it close and it worked, moved it away, nothing, moved it close and it worked.
So here's my thought, what is the possibility that the key fob’s radio signal is being picked up and "boosted" (locally only, I don’t believe the radio signals would be transferred across the cellular network) by the cell phone's more powerful radio when it is in close proximity to the phone? And if this is the case, I guess it really doesn’t matter if you are talking to someone close to your car or not – the cell phone’s radio just needs to be transmitting? I'm going to do some more testing....

Dexter, that seems to be pretty much my experience too, but it stopped working for some reason.
I am going to try again with my cell phone and see if that makes any difference.

I've tested this using two digital cells phones and it works from several miles. The one time I NEEDED it to work no one was at home with a cell phone and the home phone didn't do it. My quess is that the fob uses a digital signal so the cell was compatible but the home phone (cordless) uses radio a radio frequency and doesn't replicate the signal exactly.

This actually has worked for us in the past on several occasions. No shit it really did work. My son locked the keys in the car twice and my wife once. We also tested it when we first heard about it.
But my wife just tonight locked her keys in the car. We tried it with several phones tonight and couldn't get it to open so my son is driving the spare keys to her. Land line and black berry and cordless landline phone to an unknown brand cell phone didn't work. Could be the phones could be the key fob my son says that this particular fob doesn't open the doors half the time when you are standing next to the car. We could speculate all day weather it is true or not but for me I know it can be done. It is just a matter of conditions. 1. two cellphones, 2. make model of car, 3. condition of the key fob. If harmony isn't achieved you get to go for a drive.
