There's a feature that's been around for years, but a lot of car owners have no idea they have it: rolling down the windows with the key remote. Unless the car dealership told you about this trick or you happen to read manuals for fun, you probably had no idea.

The trick usually involves pressing the remote's unlock button, releasing it, then pressing it again and holding it down. In some cars, instead of using the remote, you can insert your key in the door lock and turn it clockwise, release, then turn it clockwise again and hold.

The trick apparently works on these vehicles:
