5 Hi there I fully understand your confusion. Recently I wanted to open my own KR 4500, and honestly it took me some time to realize how to do this. However, you do as follows: Leave the piano on the stand and remove 7 small bolts/screews on the bottom side of the piano (3 in each of the right and left side and 1 in the middle of the bottom plate). After removing these 7 screews you can lift up the upper cover, which is hinged in the lower back of the piano. You can open it approx. 100 degrees (then it is supported by a thin wire in each side). Hope this will help you. best regards Christian Smedegaard (a danish Roland player, who bought my KR 4500 back in 1993, when I was living in Japan).

5 My Roland keyboard has one key it produces either no sound or un-attentional loud sound. I opened it up then use an air blower to blow then clean a rubber part that makes a key touching down the board. The procedure has solved a problem. I guess once for a while, the key was little sticky, so just clean it would help.

2 I'm not sure this is the same piano but probably close. I got mine open with the help of a service manual I bought online. Opening it up today, I'm no closer to fixing it. I checked connectors, etc. but no go. 9 non working keys are random on lower end of keyboard. Any suggestions would be greatly appreciated. Thanks, Joe

0 I was able to open my KR 4500 with the help of Joe's advice above. The stuck key was repaired by filing a small amount of plastic off both sides of the stuck key at the end of the key nearest the pianist. For some reason the plastic had swollen a bit and cutting it down just a little solved the problem. Walter

0 I probably described this incorrectly. "Stuck" really meant non-sound producing. Keys feel the same as others but produce no sound. Problem seems more electrical than mechanical. Thanks, Joe

0 It seems that quite a few people got their Roland intelligent keyboards with F# key problem. Most problem is that the key does not feel sticky but produce no sound or scrappy sound.
