We’ve all heard the story: Someone locks his car keys and remote car opener inside his vehicle, and can’t get back in. He does have a second remote car opener at home, so he calls up his home, where his wife/roommate/whatever answers. He asks the housemate to hold the second remote up to the phone and activate it – and it unlocks the door.

Now is this true? Check out the video below to find out.
