A ribbon cable is attached to the back of the keyboard. Avoid lifting or moving the keyboard more than a couple inches before you disconnect the ribbon cable or you may damage it.

Carefully pry up one of the top corners of the keyboard with a prying tool. Slide the tool along the top of the keyboard to release it from the housing. Pull the top of the keyboard towards you an inch or two.

The keyboard may make some cracking noises as you pry it from the casing. This is expected.

Pull the keyboard up and away from you, as it is held in by clips in the front. It is not yet disconnected.
