Lock-codes

Lock-codes were used on the entrances to civilian homes, located on Coruscant, around 7 ABY. To prevent the spread of the Krytos virus, some infected individuals would seal the entrances of their homes and scramble the lock-codes to keep others away. Lock-descrambling units were used by health officials in an attempt to get to these victims.
