I have a Razer Blackwidow (RZ03-0286) that I bought back in 2020 and over the last couple of days I have noticed that a couple of my keys are unresponsive. Specifically, the 1, 2, 3, 0 and Enter keys of the number pad do not do anything when pressed. In addition to not producing an input effect, they do not light up. The light under those keys does activate when triggered by another part of the keyboard. The down arrow key has the same issue. I have gone through the troubleshooting steps, including disabling Razer Synapse but nothing has changed.
Is this something that can be fixed, preferably without sending it away for repairs?
