How to disable the Lock key on a non-Mac Bluetooth Keyboard

I have been searching the Internet for the answer to this, and it turned out to be quite simple.

You don't need Karabiner-Elements, just run:

defaults write com.apple.loginwindow DisableScreenLockImmediate -bool yes

That disabled the stupid Lock key above the Delete key! I hit this thing all the time, and I have a really complicated password!
