Keyboard Replacement on Sony Vaio PCG-FRV37

[CW4614]

I need to replace my keyboard on my Sony PCG-FRV37 and I am unable to open the case. I have removed all of the screws that I see but it seems to be getting caught in the middle and back. I do not see anything that could be catching it.

On the bottom of the case there should be screws that say {k} that's for the keyboard to be removed.
