Corsair K70 Mk.2 keyboard "D" stopped working


Recommended Posts

Hello guys,

I have a Corsair K70 Mk.2 RGB MXCherry Red(English) keyboard . The "D" key on my keyboard stopped working yesterday during an Fo76 session.

Have tried to a keyboard soft-reset & iCUE 4 clean Install. Sadly this did not restore function.

The hardware lighting still works on the key though. Bought the keyboard 1 year & 7 months ago.

Are there any options or methods to resolve this issue myself, or should I go to service center?

Any advice appreciated.

i am  having the same problem with the left shift key.  i have had this keyboard for less than 4 months.    i also tried doing a factory reset, and updated my iCUE 4.  Any help would be appreciated.

I have K100 OPX switch keyboard with a "D" key issue as well. As far as I can remember all of the keyboards I bought from Corsair develop an issue on them right before or after the warranty expires for me. I have cleaned mine but I do that normally every 3rd day to begin with. Tried the compressed air and it didn't help.

I am not sure if corsair lubes the switches from the factory or not. I am wondering if the lube might have dried up and is causing the issue. I mean something could get in there but it is a slim chance with the space tolerance. I mean something would have to blow up under the key cap and fall between the stem and the switch. But anything is possible in this day and age.

Mine works okay if you are fast hitting it. But if you are holding it down or typing slow, it down it gets stuck at the bottom. It makes the whole keyboard lag and causes other issues as well from the stuck key. I wished Corsair would take the swappable switch route to fix these issues. WE can only hope for it in the future and a wireless version to get rid of that jump rope they give you for a cord with it.
