How to remove and replace keys on a Roland HP-230 Digital Piano. Technique should also apparently work with Roland HP-2700, HP-3700, KR-4700, KR-5000, Rhodes MK-80, A-80, RD-300, HP-1000, HP-1200, HP-5600, HP-1800 (likely any "SK-6" keyboard, or Style K20W keys). Caution when opening unit, dangerous voltage inside even after removing power cord. Capacitors can hold dangerous charge for some time after removal from power. Info in video is for qualified repairers only. Open at own risk and remove power cable first. Includes plans at the end of video to build your own key removal tool (SK-6 Key removal lever alternative) from a thick steel paperclip. Straighten the paper clip wire first and then follow the directions at the end of the video for correct bending measurements.
