Door tutorial unity 5?

I am trying to find a tutorial on how to make a door in unity 5. The problem is, whatever video I watch is for an older version of unity, and have old scripting. I am just wondering if anyone knows either how to, or a tutorial that shows how to make a door for unity 5.
Thanks.

I have figured out how to do it. It was actually pretty simple. I just had to heavily modify two scripts that I has using to attack an enemy and make him die. Now you click enter on the door, and it opens and closes. I just have to make the animations and textures better now, and I will have a mighty fine door working!
Thanks for the help everyone.
