Problem with keys; F also presses G

Hey guys, Im having a lot of fun using the Kordbot with Omnisphere but I have a major issue with the keybed; when I press the F key it also presses the G key. It renders the F key unplayable and while I can do a workaround with the memory slots Its getting really frustrating.

Any way I resolve this? I suppose I have to open the hardware and have a look at the buttons; is this recommended or I will I just make matters worse?

Just fixed it, the glue holding the case together was the culprit. I opened the Kordbot, cut out the glue and now it all works like a charm
