First thing I would do is turn the keyboard upside down and give it a good shake. Hopefully anything stuck under the keys will come out, along with dust, dirt, food etc. that has been dropped into the keyboard.
Failing that are the keys sticking or do they move freely? If sticking you can try to remove the key cap and try cleaning the mechanism with contact cleaner etc.
Other than that I think you may need to replace the keyboard, especially if it is more than a few years old. Being a mechanical device the keys do wear out over time.
