On my SmartCode 955, how many digits can my user code have?

You can program the lock to have 4 to 8 digits, although the first 4 digits need to be unique. For example, if you program a code 07041776 then you cannot use 0704 as the first 4 digits of any other code. So you cannot program 07042019. or 07042019, since the first 4 digits (0704) are the same.
