BleepingComputer.com: Keyboard - Ignoring Keys

This started a while ago, and as Im on the affected computer its quite hard to type this because my single quote key is broken and it randomly types, thus I require a program to block this. Although I am adept with computers and could probably write my own program to do this specific task, I would like to know if you know of any programs that already do it to save me the time, I am having trouble finding one. Its very annoying and doesnt happen all the time, I have tried the windows accessibility feature of Filter Keys, but that is not what I want. Im pretty sure it isnt a virus or punkware, I believe it is hardware

So please, help me find a way to:
A.) Fix 'my LAPTOP's keyboard without replacing it (it is an internally connected laptop and replacement keyboards are ~$50)
B.) Introduce me to a program that can block a specific' keys keyboard input

Also, since the single quote key on Firefox activates quickfind, it is especially annoying while using Firefox and I have been forced to actually use Internet Explorer a couple of times '''
