Unique Key modes use a unique 10 digit serial number that is entered before each half of
the master key to allow the processor to bind the key to the terminal ID automatically.
In cases where the processor provides a serial number that is less than 10 digits, zeros
must be added at the beginning of the number to equal 10 digits.
