So, since some days know i have a little problem with my steelseries 6gv2.

I strafe right with the "h" key. But sometimes the key doesn't work when i press it. Basically it stops working for like 0.5 secs and then when i press it again it starts working again.

I tried to remove the key with a knife, with success. But i don't know how to remove the black switch, so, how do i do it ?
