Using a soldering iron melt the plastic keeping the the two small metal plates on the backside of the keyboard in place.

Again using the soldering iron melt the plastic keeping the keyboard in place.

This step requires some patience. You have to start at one corner and slowly lift the keyboard when the plastic melts.

Don't rip it away with force as the plastic will be torn away and should be used to attach the new keyboard.

When the keyboard is loose there are still some tapestrips connected it. Remove these and then remove the old keyboard.
