Sounds like a hardware fault.

Could even just be liquid in the keyboard. Unless you've successfully removed and replaced a keycap on this keyboard I would exercise great caution before removing one -- they can be hard to get back on. But I think that leaving it to see if the problem goes away or checking the key mechanism may be your only options.
