Grr . . . Stuck On God of War 2?

Okay grr. I'm playing on Normal and I'm stuck!!!! What the heck is up with that? Well, anyways, I just got past the East Auditorium and I killed the translator guy and got the ram key thing or whatever its called. All I know is it lights up blue when I put it in the door. And when I open the door, there is a treasure chest that changes colors from green to blue. And beside that is a moving wall of spikes. There is also another wall that looks similar, but has this little round thing with some symbol I can't remember. Anyways, well both walls move towards me and I get stuck in there and eventually get squished. What do I do?
