Key not working properly

So I'm a pretty hardcore gamer , and I've had this laptop for a year now. I play alot of MMOs so I press the W alot , well lately ive been experiencing issues with it whereas it'll work intermittently . Somtimes it does nothing even after a few presses and other when it DOES work it duplicates Ws . So I popped off the W key , and found some lent inside the key and I also reinstalled the keyboard driver to no avail. I pressed the exposed key button without the W on it and its still responding ONLY partially . Problem still persists , any solutions? Any help is appreciated.

Your best option is to get a replacement keyboard.

Should not be too hard to find and are usually very easy to fit.

Yeah it definitely needs to be replaced , now I wake up and use my pc after my mom and sis been on it for hrs the shift key produces ONLY As and my A key produces varying A types.
