How is a lock code changed using a D5050 keypad and D911A or DS9471 DACT?
A lock code cannot be changed or set using the D5050 keypad programmer. Only the D5200 programmer offer these features.
If the DACT has an unknown lock code programmed in it, the D5200 will not unlock it without the exact lock code that was programmed in the DACT.
