A few tips if you decide to take the keyboard apart:
1. Work in a "clean" well-lit environment. Like a bathroom or kitchen with hard floor, so you can see the screws if they fall to the floor. Block any drains, grates, etc. with cardboard so you don't lose small parts.
1a. Have tweezers and a magnifying glass (loupe) handy in case you need them.
2. Take lots of pictures with your phone for reference as you go.
3. If you notice that screws/fasteners are "different" from each other- different length, different thread pattern, etc., make a note as to which kind go where.
4. Don't "force" anything. If it isn't coming off, there's probably another screw that has to come out. Keep looking!
5. Respect your own limitations. If you reach a point where you start to have doubts about being able to put it back together, then stop.
