‘C’ is a special char here. All codes must start with it, leaving the rest grouped in two groups: numbers, then letters. X Y Z is a pretty common placholder for ‘11’ ‘12’ and ‘13’. ‘C’ will also function as a clear button, to begin entering a new code attempt. Probably why they chose ‘C’ as a simple label.
I may have gone with left to right then top to bottom, instead of top to bottom then left to right; but that’s more personal preference.
