BlackWidow V# Pro double or missing key strokes and volume control

Ive seen on the forums in regards to double and triple typing or no typing when pressing certain keys and also the volume going up or down on its own whether you control it or not with the volume dial. Ive done all the usual procedures (removing and adding software and updating, which all were already, etc etc) to no avail.  I am over my warranty but am wondering if Razer would still accept my keyboard to repair or such ? I feel like a $200 keyboard wouldn't have issues like this. Any information is greatly appreciated. Many thanks in advance
