This discussion reminds me of how picking up my water bottle from the cup holder in the center console of my Honda CRV will often cause the "radio" to switch from playing CDs to FM radio. I have experimented some and it is NOT my accidentally hitting the FM button with the water bottle, it's proximity. Your keyboard may have a flaky solder joint so that connection is more susceptible to EMI noise.
