Its a Razer Blackwidow elite I got for cheap, the listing just said "sold as is" and had some pictures. Didn't mention anything about bad keys. Kicking myself now for trying to cheap out. My question is if there is anything I can do to repair it. If so is it worth doing? The switches are not hot swappable if that's important.

Sorry if it's a common question I can't afford a 3ds right now but I want to have one in the future.

I looked at some of those apps that claim to teach you, but I'm not really in a position to pay the hefty subscription some of them require. Any books or the like I could take a look at?

I have a Pokemon Scarlet joycon that stopped working after I opened it up for a repair. I double/triple checked everything and it's all connected, I let it charge and nothing. I don't really want to send it to Nintendo since they don't guarantee a replacement of the same style. Should I take it in somewhere to be looked at, or should I just buy a replacement and do a shell swap?

I know it's just a far of dream but it'd be cool if someone found a way to pull it off. Not super experienced with federated media so I have no idea the logistics behind it but I just think it would be neat even if it's a smaller board.
