I have had the Casio GP 300 for 3 years now and some of the keys are just now rattling/clunky most likely in the same manner as yours did. How to describe this? After I depress/tap the affected key, the key reverberates/rattles back in place making a mechanical noise. This can be very distracting during performance, and more noticeable when using headphones. I contacted Casio, and it took several weeks before Casio finally responded with an email. Casio provided me a list of Casio service providers throughout the U.S. by state. Luckily, there are two repair businesses in my city. Unfortunately, one service provider is backed up with work orders, and the other will get back to me after researching the GP-300 keyboard. I really love this piano. It was the most responsive, acoustic-like hybrid that I tried, and I tried every major brand. It is unfortunate, therefore, to have this issue arise. Casio states that the Grand Hybrid pianos have a 5-year warranty and a service technician will come to the home to repair. I am hoping that this is a fixable problem either by repair or, as in the manner in which your issue was fixed, by keyboard exchange. I also hope to learn what to do to prevent this from happening again. If more people find themselves with this issue, Casio should take this issue seriously and work to eliminate the problem before it arises.

I am hoping that this is a fixable problem and is considered a mechanical defect under warranty. I also hope to learn what to do to prevent this from happening again. My suggestions for you? You should fill out the form requesting repair on the Casio website. It will provide you with a customer number and an email contact after completing the form. Then, keep contacting them. My contact was through Casio America, Inc. Since you are in Canada, it is probably through a Canadian partnership. If more people find themselves with this issue, Casio should take this issue seriously and work to eliminate the problem before it arises.
