I tried doing that but there were too many keyframes. But like I said, with the other model I did see the keyframes. Not with this one. Probably a bug.
Thanks

I did that also. Brought the car in a new empty scene, same. No keyframes anywhere to be seen but the animation was still there. Probably a bug yes. 
Thanks for the replies.

Really strange...
A workaround could be to put the correct values at frame 1 and try to figure out where the next (invisible) "key" is.
Hard to describe but scroll (by frame) till the value is at its highest/lowest point and copy/paste value of frame 1.
Check if there are more (invisible) "keys by the same procedere...
And don't forget to create a keyframe at those frames so you find them later.

It is a bug, where the keys are at the timeline, but not visible. I call them *ghost* keys. But I have seen one on the materials track.
So must be something new. Maybe bring car alone to the scene and do Remove Scene Animation. Or maybe just settle with what you did with material copy.

@4u2ges
I did do the Remove Animation and it didn't work. What exactly do you mean by ghost keys?

Hmm, a bug? Put cursor on frame 1 and do "Remove Object Animation" and see if material animation via ghost keys is gone.

@ toystorylab. 
The whole car is only one prop.

@Liquid.
I did do that and still don't see any keyframes. I have another car with the same problem (mateirl in the windows is animated) and I do see the keyframes in that one. Weird. I was able to fix it by copying a material elsewhere with the eydropper that didn't have an animation and paste it with the bucket on the windows. What's funny is that it worked that way, but if I loaded a brand new material (through the load button), the material changed but kept the animation.

Thanks

Check the car in Scene Window and be sure those windows are not separate subprops of the car with their own timeline...

With the prop selected open the Timeline and click on the small arrow to show the sub tracks for the object.  



Make sure that the Material box is checked. You can expand the Material sub sections to view all keyframes. Scrub along the timeline and delete any keyframes that you don't require.
