The keys on your keyboard can be pulled up and carefully cleaned. You also clean the surface the keys are attached to, avoiding any electronic components visible. You must be careful when removing the keys, you could damage the locking mechanism. I would suggest a forum for your exact model of computer. That will let you know how your keys connect and the best way to remove them. You could also attempt to blow out the keyboard with air, cleaning out dust and dislodging any tiny object that may have gotten stuck under a key. They sell the air in most stores.
