Animation moving to pos (0,0,0) and rescaling

(Unity 4.0.1) I am having a problem with the new unity concerning my animations, I am trying to animate a door, to simply swing open when my character is within a certain range, there appears to be nothing wrong with the settings for the door, it has a mesh collider and a box collider on trigger (problem occurs without the colliders aswell). My problem is that the mesh animates, but also moves to position 0,0,0 and rescales. I could solve the moving problem by adding an empty parent, but the door will rescale to the origional size no matter what i do with it. There are three tabs in the inspector for the object when its newly imported, Model i have changed nothing, Rig i have it set to Legacy (otherwise the animation wont work) and in Animation: Import animations checked, bake animations not checked (have tried with and without, with no difference), wrap mode default, unchanged animation compression.

no matter what i do, the animation either will not animate, moves to another location, or rescales - any help is appreciated. My other animations work perfectly the way they are supposed to, (rabbit, dog, etc.)

the door is animated in Autodesk Maya, and we have tried several different things in Maya and the problem seems to be within Unity.

Thanks in advance.
