It can be dirt, spilled liquid, connection to controller chip, or cracked/corroded trace. Any fix requires opening it up. Look it over carefully before doing anything. You can use either water or electronics spray cleaner for the electronics itself, but the case and keys may not be solvent resistant. Water has to be completely dry before re-assembly. A corroded trace is usually obvious but a trace with a hairline crack might require a meter to find. Fix a cracked or corroded trace with a conductive ink (or conductive epoxy) pen.
