The W,S & X keys on my 2012 Macbook Pro keypad have suddenly stopped working. I just cant type those three letters.
I was using the Macbook and the keys were working fine, then suddenly they stopped working. Every other key is fine.
Strange that the affected keys are all in a near vertical line from each other.
Anyone know if there's an easy DIY repair I can do please?

I doubt there are any DIY repairs for that. You'll probably have to take it to the manufacturer for repair.

Just discovered that the number '2' key doesn't work either, so thats a near full vertical row of keys not working - 2, W, S, X.

Might have to make a Genius bar appointment at my local Apple store for them to have a look £££££££.

Finding it difficult to type posts on forums like this with my keyboard.

The key encoding (process that the keys use to communicate to the CPU) are aligned in more-or-less vertical columns. So, all those keys (2, w, s, and x) communicate through the same "line".
It's a typical result of a failure in the keyboard encoder. It's part of the keyboard itself.
You fix that by replacing the keyboard.
2012 MBPro is the change-over year from the older unibody style to the "retina" models.
Either model is a top case replacement (unless you can discover replacement keyboards), and Retina seems to be about 3x the cost of same replacement in a unibody.
Not cheap, nor easy to replace the keyboard. Check it out in iFixit.com
( If you just want a working keyboard, use a USB wired, or even a bluetooth keyboard. You're less portable, but it works. )

That interesting, thank you. Just been recommended an independent local guy who specialises in preparing Apple computers so I'll take it for him to look at.

Is it possible something was spilt on the keyboard?

No, not to my knowledge.
I've arranged for the independent repairer to fit a new keyboard, which is costing me £80, and also a new battery whilst he's at it.
