How to fix Xbox 360 disc tray automatically opening. (SIMPLE!!!)

The tech store wanted $80 to fix my xbox. I thought that was a rip off because it couldn't be too hard to fix. I am basically computer illiterate and by no means a gamer. I was able to take apart and fix the xbox very easily, so you can too. Here is a short video explaining what the problem was with my xbox (the common problem when the drive automatically opens) and how I went about fixing it. Please like this video so other people experiencing the same problem can fix the xbox themselves instead of getting ripped off by the tech stores!
