Not too long ago I noticed that the key "a" and "s" started to chatter and input up to 5 characters from one press. I found this really frustrating since it wouldn't go away and blowing into the switch makes it go away for about 5 minutes, but then it comes back. I have lubricated the switch with isopropyl alcohol, but that didn't work either. This started happening about a year since I owned this keyboard and I have not found a fix for it yet. I would be really glad if there is a fix for this key chattering to stop.
This is what it looks like:
s sss s s s sss ss s s s s s ss s s ss ss

What keyboard, what switches, etc? :p

Razer Blackwidow 2014 Razer Green Khail switches, they are really quite similar to blues.

Take a photo on S situation at the back of PCB would easier to found the problem. If the press action of the S switch is not different to another switch. That should the problem of PCB contact.

I don't think that the faulty PCB contact may be the problem since I haven't really dropped or banged on my keyboard to farther disconnect the connections between the switches and the PCB. Also as I have stated before, blowing into the heart of the switch when it's pressed down helps for about 5 minutes which only proves that it is not the fault of PCB contact.

firstly: IPA is not a lubricant
secondly: if it isn't the switch itself or the connection to the PCB you are mostly out of luck.
thirdly: troll post?
also: why didn't you return a broken item?

It isn't a troll post, I think it is the switch itself chattering since only the "s" key is doing that. I can't return the item since I only had warranty for a year and it has been over a year since I got this keyboard. Also, I used IPA to try cleaning the debris inside to see if that was the problem, however it did not help. I might be a dumb ass for doing that but I have tried anything I could except repair via full disassembly which I can't do due to a lack of knowledge about saughtering.
