To replace the keyboard you only need to remove one screw (marked KB) on the underside of the laptop. The keyboard can then be easily removed by taking off the plastic bezel by the top row of keys and unclipping from there. Literally a 5 minute job without the need to fully disassemble.

Thanks to your advice, I got rid of unnecessary and unnecessary disassembly work.
