my animated object wont turn on the spot....

i made a object that uses key frames to move around and animate but i cant make it turn to face the other direction...
if i use a look at and tag it works but doesnt spin on the spot
cant use a ball joint
if i use a key frame to make it flip to face right it only half works with the other key frames on.
if i use a rotator it doesnt work at all because the key frames wont let it.
