Abstract
A removable programming unit (11) is connectable to a controller (40) of an electronic locking system (12) of a storage assembly (14) via a telephone cord (38). The removable programming unit (11) comprises a display (52) and a keyboard (54). Through the removable programming unit (11): new access codes used to gain access to the storage assembly (14) may be programmed into the electronic lock; existing access codes may be modified as to which storage units (18) may be accessed; or existing access codes may be deleted. All existing access codes are stored in the memory (92) of the controller (40). The removable programming unit (11) receives 12 V DC from the connection to the electronic lock (12) via an individual wire of the telephone cord (38).
