Keyboard Keys Not Working Yamaha PSR - E423

The first key on the left and the last three keys on the right have no sound when I press it. Whenever I press it, it seems that there is something that is blocking the thing inside that's why it can't be pressed smoothely. Unlike the other keys. How can I solve this problem?
