Question Is this keyboard fixable?

[Giant Hunger]

I found a guy selling his faulty razer widow ultimate 2016 for just $15, so i thought why dont i buy it and go and fix it.
The guy said "I bought it for about $100, after using it for a while, I went to work and only used it on my laptop, so I left it at home. After a long time, during this epidemic at home, I used the keyboard again, but due to a long time, the keyboard was paralyzed with a few buttons as shown in the picture. Because I don't use anything anymore, I will sell it to anyone who needs it or fix it to use it again. The key cap is beautiful, no peeling or broken."
The pictures:

So do you think this keyboard is fixable? And how can i fix it?

If you don't already know what is wrong with it, or already have a stack of like keyboards to swap parts around....you simply paid for someone elses trash.
