Hello. I was recently cleaning my keyboard with some 70% isopropyl alcohol. As I was cleaning it with a cloth, a small amount of liquid leaked into the 8, i, and K keys. I would say that the amount leaked inside would be equivalent to 2 or 3 drops. I let the laptop dry for around 24 hours after the cleaning and I turned it back on. Soon after I started up the keyboard again, I noticed that the i key would input letters like ER. Another example is after I pressed 8, they keyboard would input 1238. This happens the same with the K key. What are the best possible options to fixing this? Should I replace the keyboard or the topcase? Any suggestion would be appreciated. I have tried SMC resets and everything. Thanks for the help

Replace the keyboard.
