a dying key?

[Neo.X]

One key of my keyboard acts wierd. If I don't use the keyboard for couple days, when I connnect the keyboard, this key won't register at all. But if I leave the keyboard connected for a while, it starts working. It looks like it needs some warming up. 

Could this be a switch problem, or soldering problem, or worse,a trace of pcb problem?

Thanks

take it apart and resolder the switch

I might end up doing this. But I like to know what's the possible cause for this kind of issue before I disassemble it.
Thanks

most likely an intermittent solder connection. I would reflow the solder on the switch and replace it if that doesn't fix things.

Thanks, I hope it just a solder issue, which is easy to fix.

So it shouldn't be the trace of the PCB because the switch registers fine after it starting working, right?

no, my friend. That one works fine. It's a Korean Customize, bad luck of me. 

I might need your help for this one as well.
