If the keyboard is still under warranty, the best thing to do would be to take it to a certified Casio service shop to be checked out and repaired. But if it's no longer under warranty, the problem might be fixable by opening up the keyboard, disassembling the key assembly, cleaning everything-- without damaging any electronic contacts-- repairing or replacing anything that needs it, and then reassembling the keyboard. There are videos on YouTube which show people opening up a Casio PX keyboard and doing that sort of repair:
