I plan to redo the art for the Security Keypad (and maybe do additional keypads) at some point in the near future. It may not seem like it, but that keypad is an unoptimised nightmare and it needs to be taken out.
It still boggles my mind that there wasn’t a 0 included originally.
I’d make a suggestion about this on the IO connection Megathread, it’s more likely to be seen there.
