I picked up a BlackWidow V4 Pro Full Size about a month or two ago. About 2 weeks ago, my left shit key stopped working fully and now only works every 1 out of 4 presses or so and even when it does work, it will stop working about 50% of the time. Nothing has been spilt on it and I have removed the key to see if something was stuck under it but I didn't see anything. I also have an issue with certain keys activating twice with one click like my N and my S key, but that's not as much of an issue as the shift issue.
Does anyone know how to either fix it or am I going to have to sadly replace my keyboard as I use my left shift key all the time?
