Peripherals keyboard buttons

I have a microsoft sidewinder x6 keyboard. I believe it to be faulty as it doesn't pick up light typing on certain letters. i tried sending it back but overclockers uk are being annoying about it.
Is there a way that i could replace the actual buttons inside the keyboard because i really like it.
i have a spare keyboard i could use but i prefer this one even though i have to correct everything because they are missing letters.
Would be a real shame for it to go to waste

So it picks up heavier key presses on these keys? Are the keys near each other or completely separated?

 

You can RMA it to Microsoft, if it's under warranty.

 

the heaver presses are picked up, and the keys are completely separated.

and i did not know i could RMA to Microsoft. will try that.
Thanks
