Help Please! Recent Keyboard problem...

[apaulfx]

Ive been using my macbook for sometime. performs very well but just recently i booted up my macbook and my "<" button has stopped working all together. This is also a problem considering i cant use any commas. but on top of that my trackpad is having issues as well.
I can still scroll up an down with two fingers. However the double tap "right click" feature has stopped working.

I have checked my system settings and everything set up normally. Is there anyway to reset my keyboard?

I have even gone as far as taking my top case off and replugging it back in. ( using http://www.ifixit.com/)

Please keep in mind my macbook warrenty is voided due to its age but being a web designer the "<" key is pretty nessecary...( i had to copy and paste < just to use it)

I have a black Apple MacBook 13.3-inch 2GHz (A1181)

Any help would be much appreciated!!!! 🙁

That's very odd. Have you tried zapping the PRAM? On startup, hold command+option+P+R until you hear the chime a second time.

apaulfx, by chance, is the plastic near either palm rest chipping on your computer? Here's a picture with an example.

No Chipping that i see.

Now I just tried to attempt the PRAM reset and im unable to do so?
Both the option and command tab are working correctly but when I attempt to hold down those buttons the boot screen just loads as normal. As if i never held anything down? I also held down the alternative buttons but got no similar response.

On an interesting note, I plugged in a usb keyboard and im getting use of my , key on it. Regardless of this being a temporary solution I am still baffled at this strange situation....

Also, Sometimes doing the reboot my comma key turns itself on?
example: on boot ill hear the noise of a key being pressed down and once i click a text box i get (,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,) until i press another key to stop it.

I really appreciate the responses!!!!!🙁

"Alternative buttons"?

shift at restart for safe mode.
and option by itself for sound.

neither had any response during boot.
