Good Day,

Is there any way to disable a key in a built in code (not device upgrade) to the point that pressing the key will not light up the LED?

Thank you!

No, you would need to replace the code with an upgrade to completely disable the key. If simply causing the button to no longer perform it's original function is sufficient, you can keymove a "bad" advanced code onto the button, but it will still light up the red LED.
