My granddaughter has a CTK-720 with broken keys. We have obtained replacement keys but I’m having trouble removing the cover of the keyboard so I can get at the keys. I removed a total of 16 keys from the bottom and the cover is loose on the ends but not in the middle. Can anyone help?

I found a company in California that sells parts for the keyboard. The list of parts for a Casio CTK450 is at:

I might be a customer, because, while I am fairly delicate with the keys, I do tend to get a little exuberant now and again. It makes no sense, because extra force does nothing to affect the tone!

Great find xenonlit. Thanks for sharing. I did run a search on the web to see if anyone was selling the part, but didn’t find any. Never occurred to call Casio directly. If I get some interest, I’ll buy a few sets and stock them so people can use me as their ‘retailer’

HA! I called the Casio parts department and you can get an octave worth of keys by calling 1-800-223-2001. For my Casio CTK 700, the part would cost 12 bucks, including tax and shipping.

The bad news is that the parts are backordered for several weeks, because everybody runs out and buys a new casio, so they don’t make them that frequently.

Please spread the word so that they will.

Wow! My “D” key just snapped yesterday! I thought that I would try to see if anyone had a repair and here you are. I’ve had my Casio for exactly two years, and hoped to have it for at least another couple of years.

The fact that the break occurs at a truly obnoxious join where the pressure is going to be immense, indicates that maybe we should be able to buy the whole assembly and replace it!!!!

I will try your fix, but with something more flexible than tin, like some malleable plastic or fimo clay. That tin looks to be pretty thick, and may be too heavy in relation to the cheap plastic, which may be engineered to break and to require a new purchase.

finally, I’m looking up parts for casio keyboards. Do you have a part number for that assembly?

Same thing just happened on my Casio CTK-720. In my case, middle E bit the bullet. From what I can tell, it’s the same key situation, but I’ll open it up anyway just to make sure. Sadly, the keyboard is one week short of its first birthday.

I guess we just rock too hard, friend.
