This may well be because they manufacture all their own calculators? So its always been in-house?

I think the older Casio keyboards were more reliable than the later keyboards. They tend to use conductive rubber contacts in silicone rubber domes these days, which are prone to failure due to wear or (for some manufacturers of remote controls, maybe not Casio) leaching of plasticizers. The earlier models used non-conductive silicone rubber domes activating a membrane keyboard underneath, and also had double-injected plastic keys - none of this printed rubbish!

Having said that, I haven't experienced any reliability issues with Casio keyboards myself, unlike TI and later HP models.
