Object teleports away!

Hello! I am having a problem with unity. I am trying to add an animation to my door (just opens up), but everytime the it happens, my door teleports to different position. I already tried to parent it, and I did it already tried to animate it within unity, wich works fine - but the animation was done in 3D Max and I have to do some other animations I want to do in 3D Max, but if its not working... below you can find a video, hope that helps to understand my problem.

 

Looks like (maybe) the pivot point for the door is off - where the door jumps too in Unity.
Confirm the door pivot point in Max is correct before animating it.

Also - might consider animating this in Unity since it is such a simple rotation animation. No need to complicate anything by importing a simple animation like this into engine.

 

Thank you! Yes, I did in unity and it looks much better
