A self-service, fully-automatic kiosk for duplicating keys includes a kiosk housing having a customer interface for receiving payment from a customer for the purchase of at least one duplicate of the customer's key. A key analysis system within the housing analyzes the blade of a key inserted in the key-receiving entry to determine whether the inserted key matches one of a group of preselected key types and, if so, which preselected key type is matched. A key blank extraction system extracts from a magazine within the kiosk a key blank for the preselected key type matched by the blade of the key inserted in the key-receiving entry. Then a key duplicating system within the kiosk replicates the tooth pattern of the blade of the key inserted in the key-receiving entry, on the blade of the extracted key blank. The kiosk includes a processor coupled to sensors and controllable devices within the kiosk and to a communications port for communicating with a remote central server. The processor displays multiple available manual commands in response to an input signal requesting such a display, and, in response to manual selection of the commands, produces signals that energize and de-energize selected devices within the kiosk, thereby permitting remote manual control of the devices and mechanisms associated with those devices. The processor also transmits signals from a video camera within the kiosk, and signals representing the status of multiple devices within the kiosk.
