Keyboard L key acting strange.

[Nekolace]

So basically, pretty recently, my L key on my keyboard has been acting up and it's getting on my nerves. Sometimes, if i press it, nothing will happen until i press it 4-6 times, and other times, pressing it makes it put two L's down. I have a Corsair K70 RGB, and have never had this problem before. I can't find anything on the internet, but I may not have looked hard enough since I'm not even sure what to look up. Any help is appreciated, this is getting quite frustrating!

Use switch Hitter to see if you are getting key chatter. I have the same keyboard and it does it with the O key rarely.
