I inherited a water damaged laptop and only problem seemed to be the keyboard. So I replaced it but the keys are mixed up i.e. when i push J or K it comes up with 1 and 2. I've cleaned the connector but still nothing has changed. Can it be fixed?:knock:

The water may have damaged the keyboard controller... Have you made sure you have the proper keyboard? Maybe the "new" keyboard is bad

You have num lock turned on.
