I can't open the back to change the batteries in my TI 83 plus calculator. I don't think there is batteries in it. What should I do?

Okay, these buttons respond, but...each button below VARS does not respond on press but DO upon release, although they act as if VARS was pressed. Upon pressing these keys for some time, other keys will become inactive until you press "normal" keys enough times (usually 2-5 times) The TI Connect says my battery level is "good," and I'm not quite sure this is a key-circuiting problem. Any advice?

*Update*

I made a program to test what "key" the calculator is receiving (Getkey->A ; VARS = 44)

indeed, each key below VARS responds with 44, and sometimes, like mentioned above, don't register as "pressed" if i pressed a broken key repeatedly. Update: sometimes, other keys are regarded as VARS after pressing the broken keys, and sometimes even act as if VARS was pressed twice; other keys still function as normal, otherwise.

I press "On" and the entire screen turns a darker color, but nothing else appears when I touch the buttons. When I touch 2nd "Off", the screen goes back to light color as usual.
