Now some of you might have seen the video where they use the seat belt to go through here and they click it in if you're trying to sleep in your car so they can't open the door. Now what if there's no opening here? This one really bugged me and I spent a lot of time trying to figure it out. The first step is roll the window all the way down, use this to pull it all the way out, and open your door, you're gonna go over right here, all the way to this side right here, and keep it shut. Now you've got this. Now repeat it on the same side. Now once you set up the other side, I use two carabiners, one goes in here, and you've got a little bit of slack to get it in, and then you're gonna readjust it right here. You're gonna open your door a little bit, close the window, and you're all set. No one's gonna come into your car.
