Open the front end of the keyboard with a prying tool.

Using a heat gun on low setting can be used carefully to heat the rear cover and soften the adhesive. Work in sections heating and then gradually prying the sections apart.

Avoid using too much heat otherwise you will distort or melt the cover or other plastic parts. Do not use excessive force to remove the cover as the alloy is thin and bends easily. The keyboard will be permanently distorted.
