How to swap a hot swappable pcb for another one

Learning and discussion
1

Basically, two years ago, I spilled beer on my hot-swappable keyboard, and now two keys no longer work. I haven’t found much information online about fixing it, so I think the best option would be to swap the PCB altogether. I don’t know much about keyboards since I bought mine prebuilt from KBDfans, which is why I’m coming here. How hard do you think it is to swap out a PCB? Any recommended videos or advice for my situation would be greatly appreciated.

What is the exact make and model you bought from Kbdfans? There’s a halfway decent chance, but we’ll need to know what we’re dealing with.

Looks like maybe the YMD75, Tofu84, and XD84 would be compatible, and there’s a random AliExpress store still selling a solder PCB for the KBD75. KBDFans still sells PCBs for the Taco75, but I don’t know if it’s compatible. There might also be open source PCBs on Github that you could have fabricated. Hopefully someone else will have more direct experience.
