Asus N550JV Keyboard not working properly

[Kambi13]

Hi there need some advise. I have an Asus N550JV-CN102H with board N550JV Re2.1 suddendly started to behave weird, with almost no keys working on keyboard, opening random stuff, touchpad also working weird
Nothing has been spilled. Tought, well keyboard has gone bad, ordered a replacement one, installed it, and to my surprise the issue remains the same....
I'm wondering if the EC has gone Bad. Updated Bios also, but with no avail.... Does anyone knows if ITE IT8585E/FX has to be programmed?

Any thoughts? I've tried out disconneting the internal keyboard and plugged in a usb keyboard and it does the same. Might work for a while then stops responding, Touchpad wont left click and start right clicking with no user action
