My keyboard has two keys which no longer function (one being a p which is a real problem when your name is pete!) I'm fed up having to cut and paste the letters. I've found the part but not sure if its easy to fit for a non techo.
Can be pretty tricky, i wouldnt recommend it if you aint a techy. But for a person in the know how should take approx 15-20mins to replace. Mainly it about unscrewing the keybaord, removing the connector (which is quite delicate) and replaceing the new keyboard and screwing it all together and replacing any trim etc.
