If you want to create a code starting with 0 directly from the system cabinets display, you will fail, the cabinet does not handle the 0 as a true value when programming, i.e. when creating codes directly in the cabinet the digit interval is 1-9.
However, if this is important to you, you can create the codes in keywin light, then transfer the codes via the USB flash memory to the cabinet, and then the code will work even when starting with a zero.
