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.

    Thanks for looking that up! I could be wrong, but I think that boards with N-key rollover generally do use a matrix but with the addition of diodes to prevent ghosting. (Details on Deskthority.) The only designs I’ve seen that don’t use a matrix are small split boards with fewer two dozen keys per side/controller where it’s practical to get a controller with enough IO pins to use a separate pin for each key.
