Have you accidentally locked your keys in the car?
This is quite interesting and may come in handy some day!
Assume your car key remote is locked in your car and you have a spare remote
with spare keys in your house. This also assumes that you have a mobile
phone on you.
Call some person at home on your mobile. Hold your mobile phone about one
foot from your car door and have the person at home press the unlock button,
holding it near the home phone at the other end. Your car door will
unlock!
Saves someone the trouble of 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, for that matter).
This really works. It has been successfully tried out over and over again.
