I don't usually comment on the Fake/Non Fake arguments, but this was tried on Mythbusters and it doesn't work, there is someone out of camera shot who presses a button on their car keys, which remotely unlocks the car.

That's what I thought. Homegirl needs to brush her teeth too.

i wish that worked.

You gotta love it when cute girls turn out to bed bad
i know i do

It does work, but only on certain older, crappier cars, and a lot of foreign cars. However, the inside of American car doors is not air-tight. It doesn't matter how much air pressure you generate, because it's just going to disapate throughout the rest of the door.

That's nothing more than science fiction!

if you think this works you are an idiot
