Broken scroll button - replace?

[murak]

The scroll button on my X230 keyboard got ripped off, is it possible to buy a new one and replace it yourself or is a new keyboard my best option? Right now I scroll by holding the small green rubber thingy that sits beneath where the button is supposed to be, so nothing apart from the button is broken.

You should be able to replace the whole key/button.
