Object locked in one position and impossible to animate help please!

so I just animated the shape keys for a character and now i want to animate the object so I tried “I > RotLoc” and I added a key frame but then as soon as I move the head of the time line it goes back to like a default position despite the key frame and i can’t seem to get it out of that default position.

I’ve worked with this model before and didnt have these problems any ideas?
P.S. its the object isnt parented to anything
thanks!

Your question is a bit vague;

Is the object a Mesh Object and does it use a Modifier (armature, meshdeform etc)?
Is it the Shape Key or the Object that goes back to default position?
What frame did you I-Key it on?
