hello wonderful folks, I have a Ducky One 2 SF and recently my Tab and Esc key stopped working. I’ve taken the keyboard apart (as much apart can be taken without de-soldering the switches) and cleaned it all out. The switch itself works (verified using a multi meter and shorting the pins in the back with a screwdriver) however the signal isn’t sent to the computer. I’ve verified using a keyboard tester website to verify that every other key is registering except these 2. Anyone run into something similar?
That definitely sounds like a PCB issue then. I’d say desolder those two switches and maybe one or two others just to check and try shorting the sockets on the PCB. If you still don’t get a signal and the switches definitely work then you’ll have to replace the PCB.
I’m not sure what Ducky is like with warranty or sending replacement parts but that seems like your only option apart from getting a new board.
