Greetings,
Brett may be right.
As I type this, I have my Satellite up and running with its THIRD new keyboard....and it doesn't work all the keys too....
They are 141 at Best Buy, installed, or 25 on Ebay. Remove 3 screws on the back, a two movable tabs that hold the ribbon from the keypad to the mother board ...LIGHTLY PRY the easily removeable board, reinstall new BAD F**King board, gently press in and reinstall the two (yes...Best Buy lost one of the three screws on the last installation....nice) three screws and you're back in business.
Hope this helps.
