Hi,
It would be highly unusual that 3 keyboards (original plus two replacements if this is what you mean) exhibit the same fault characteristics.
The common factor is the motherboard or the keyboard ribbon cable if you re-used the same one.
Try connecting and using a USB keyboard just to eliminate the remote possibility that it is a software problem.
-Did you also clean the connector socket, with Isopropyl Alcohol, where the keyboard ribbon connects into the motherboard?

Don’t know your laptop but if you re-used the original keyboard ribbon cable on the replacement keyboards, did you clean the ends of the cable that plug into the motherboard and the keyboard with IPA as well? Try not to grab the ends of the ribbon cable with your fingers after you have cleaned them as this can make for a bad electrical connection
