Laptop Keyboard Dead Key

[Guest]

My Toshiba Notebook seems to have 1 key not working and I do not think it was from any liquid getting on it. I tried to reinstall the keyboard thru the device manager but it still has 1 key not working. Just wondering if replacing the keyboard would solve this problem without considering anything else? Recently when I had the keyboard apart there are black spots in 3 or 4 places on the back side over where the hard drive is. This left spots on the frame of where the hard drive is inserted. Could this be a problem indicating something else and the keyboard?

Keybords do wear out sooner or later, specially the scissor type keyboard used in most laptops.
