after a recent drink spill on my MacBook, the keyboard is producing all sorts of random keystrokes and odd behavior such as holding spacebar, shift or arrow keys etc. Yes, I know this question has been asked before, but I can't comment or bump any old question due to the low reputation on the site so far.
I am looking for a cheap way to disable the keyboard. Could one remove the keyboard ribbon from the logic board to disable it? I use my laptop in a 100% external mouse and keyboard environment, so I don't need the built-in keyboard to work.
I know there is somewhere to disable the trackpad in System Preferences, but I could not find anything.
Also, I saw the old way of getting to disable the onboard keyboard was by unloading a KEXT file.

Since you already know the software way, how about permanent removal (the hardware way).
Open it and unplug the cable.
