So as the question states, I am making a second door and I thought that I would be able to reuse the same animator that I used previously for a door. The old door functions as intended, however when I launch my scene and the new door has the same animator attached to it as the old door, it teleports next to the old doors location and I am not sure why. Please help!
You have to only animate child objects. Set your door up like so:

MyDoor is what you prefabbify.
Hinge is what you animate
