Have you thought about the possibility that your keyboard might be the problem? It could be dirty, with particles trapped beneath the key caps affecting its operation, or it may be damaged altogether.

Is it a mechanical or rubber dome? If it's rubber, look for dirt as mentioned by @Dukesilver27. Or inspect for any damage to the rubber layer. For a mechanical issue, the switch might need replacement.
