Chosen Solution

It looks like the keyboard is permanently mounted with the palmrest face of the laptop. But there are replacement keyboards on ebay, my brother’s laptop has a malfunctioning keyboard and I want to replace it for him without having to buy the entire assembly.

Looks like the keyboard is riveted into the top chassy. You’re gonna have to replace the entire top chassy of the laptop to replace the keyboard. https://www.asus-accessories.com/rog/rog
