A key cutting machine includes a housing, carriage, key clamp, and motor to drive the carriage. The key cutting machine may include a vacuum removably attached to the housing. The key cutting machine may be selected between manual, automatic, and semi-automatic user modes. Additional improvements or features of a key cutting machine are also described.

Implementations of key blank carriers or key blanks with a standard reference features may include alignment features on a key blank head, key blank tip, a key blank carrier coupled to a key blank sleeve and/or a key blank sleeve, and any feature directly attached to any portion of the key that may be used for referencing in the key duplication system, or any combination of these. The standard reference features may allow any key blank brand model to interface with the machine so as to consistently align each key, regardless of its make and model, for cutting in a universally configured key blank clamp that is clamped to reduce the movement of the key blank during duplication cutting.

A key model identification and feedback system includes a key identification housing, a master key receiving aperture, a master key identifier, a processor in communication with the master key identifier, and a feedback module. The processor is configured to access a database defining a plurality of known key models, compare the physical characteristics of the master key with physical characteristics of the known key models in the database to identify a model of the master key, and communicate the model of the master key to the feedback module coupled to the key identification housing. The feedback module, responsive to the communication from the processor, outputs an indication of the model of the master key and directions to a location remote from the key identification housing where a key blank having the same model of the master key is available for duplicating the master key.

A key identification system that includes a key identification system housing, a key clamp, a key ring support tray, and two digital identifiers is disclosed. The key identification system housing may include a key receiving aperture extending through housing and sized to receive at least some of a key blade of a key. The key clamp is positioned adjacent to the key receiving aperture and allows the system to maintain the key blade in a fixed position within the key identification system housing when the key is inserted into the key receiving aperture. The key ring support tray is typically coupled to the key identification system housing below the key receiving aperture. The two digital identifiers are positioned within the key identification system housing and designed to capture key blade information.

A stroke safety device for a key duplicating machine has a fixed mount and a movable mount. The fixed mount is mounted around a connecting shaft of the key duplicating machine and has a first body, multiple first resilient members, multiple pressing elements, and an adjusting element. The first body has a through hole, an inclined segment, and a mounting recess. The movable mount is pivotally connected to the fixed mount and has a second body and an operating element. The second body is pivotally mounted on a base of the key duplicating machine to cover the inclined segment, and has two opposite side segments. The abutting rod is inserted into the mounting recess of the first body to selectively abut against the adjusting element.

A key identification system is provided. The key identification system comprises an imaging system to capture an image of a master key, and a logic to analyze the captured image. The imaging system may be capture an image of a groove in the master key from an angle between perpendicular and parallel to the blade of said master key. The logic analyzes the captured image to compare characteristics of the groove with groove characteristics of known key blanks to determine the likelihood of a match between the master key and a known key blank. The key identification system may further compensate for displacement or orientation of the master key with respect to the imaging system when analyzing characteristics of the groove.

A key identification system is provided. The key identification system comprises a sensing device configured to extract bitting information from a master key, and a logic configured to analyze the image. The sensing device may be configured to capture information about the bittings of the master key, such as an image of the bittings. The logic analyzes information about the bittings of the master key and compares it with bitting characteristics of known key blanks to determine the likelihood of a match between the master key and a known key blank.
