I spilt water over my laptop's keyboard

Hi! I spilt a small amount of water over my keyboard, wipe it off then let it dry for 1 day. The thing is, as i opened it today some keys are working properly, but when i press “h” “m” “n” it automatically writes “mnh”, when i press “e” it writes an “e” and if i press it again it works like “enter”. The delete button isn’t working at all, “x” and “z” write “xz” (each one). By the way, the water was spilt only in the “n”-”enter” zone so I don't know how it got to “z” and “x”. The enter button in the right corner down works just as “e” does. What should i do? Should i replace its keyboard? Will it change something?
