Fanuc do not usually supply the control panel, only the crt/keypad, Any button, function switch etc, is supplied and wired in to the PMC as the machine tool builder sees fit.
This is why machines differ so from make to make.
There are usually three different inputs that can be used to lock out either Programs, Tool Offsets, or Parameters, but the machine tool builder will often only use one lock-out switch for all three or just the program edit.
In the diagnostic or ladder screen, see if the BMI bit for the edit enable is a 1, this is register G122 bit#3 (4th bit from right).
This will appear as an output G122.3 in the ladder.
I trust you have a operators manual?.
