That can be a common issue that develops after several years of use, or it can happen sooner if the keyboard is used heavily. The switches that the buttons control can get worn out. If that happens, you generally need to get the keyboard repaired to replace the worn-out switches, or just buy a new keyboard to replace the old one.
