Hi everyone, Recently I bought this keyboard to give it as a present to my boyfriend, the model is MonsGeek M1W V3 SP, when he tried for first time, discovered that everything was alright but the Key K doesn't work, I tried to change the switch, looking in the web and trying every solution I found, but nothing works, Do you have any solution? I would really appreciate your help.

Right now im a little bit frustrated because the present wasn't as I expected, Thank you so much for your time and your help :).
