I just repaired this same model with a soda spill. You'd be surprised what gets shorted out in the keyboard. I would replace the top case (trackpad too unless it didn't get damaged) and clean whatever (you didn't specify what was spilled, like coke is corrosive) you can with isopropyl alcohol taking static precautions of course. Definitely dis-assemble to air it out, You can even put the logic in an oven on cookie sheet at it's lowest temp with door open or in a container with a desiccant. No quick or easy way with this model.
