[TS][SurfaceBook][UK] A couple of keys have stopped working properly any home fixes or get it replaced?

The 'p' and '-' keys on my Surface Book have become sticky(?) once pressed in they rise slowly. Most of the time this will register as a single click but on occasion it will register as a continuous press.

It's the dGPU model so I am wondering if there is any way to fix it myself or if the only option is to get it replaced?
