Ok...just FYI in case someone else runs into this. I opened up my keyboard - pulled the contact strip and motherboard out. This enabled me to pull the entire set of keys out. From there I was able to pull out the offending keys and look at what was wrong. It took a long time to figure out and much trial and error but I determined that the guides had gotten ever so slightly bent from something falling on my keyboard last show I did. I was able to bend the guides back into place and put all of it back together...then a couple of keys weren't playing any sound so I had to open it up all over again and mess with the contacts for those other keys. I actually fixed it though. AMAZING !!! I called a shop before hand for an estimate and he said $60-$120. It took me 4 hours but I did it and saved a bunch of $$$. YAY !!
