A clamp is disclosed for use in a key making machine. The clamp may have a stationary head guide with a slot configured to receive a key, and a pressure pad configured to engage the head guide and sandwich the key therebetween. The clamp may also have at least a first spring configured to continuously generate a force biasing the pressure pad toward the stationary head guide, a plunger configured to selectively engage the pressure pad, and a second spring configured to bias the plunger toward the pressure pad. The clamp may further have a release lever manually operable to urge the plunger away from the pressure pad and to compress the second spring.

A universal clamping assembly for a key duplicating machine is described. The clamping assembly comprises a housing having a pair of opposed flat guide rail support surfaces and a sliding tip clamp is guidingly displaceable along each of the guide rail support surfaces and are urged against the tip of the key and key blank blades which are positioned on the guide rails. A pivoting clamp is displaceably engageable on a forward top edge of the respective key blades to apply a downward force on the key blades to ensure that the lower edge of the key blades is firmly resting against the guide rail support surfaces. A pair of cam operated side clamps is actuable to further clamp the blade on their sides at two distinct areas. The universal clamping assembly is capable of accommodating different key and key blank lengths, widths and thicknesses. The method of clamping the key and key blank is also described.

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.

The universal clamping assembly is capable of accommodating different key and key blank lengths, widths and thicknesses. The method of clamping the key and key blank is 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 assembly is disclosed. The key assembly may have a blade with a head portion, a shank, and a transition region connecting the head portion to the shank. The key assembly may also have a head configured to receive the blade. The head may have a shoulder located at the transition region to limit engagement of the head with the blade, and at least one tang located at an end of the head opposite the shoulder. The at least one tang may be configured to engage a recess located within a side of the head portion and inhibit removal of the head from the blade.

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.

An automated key duplication system that includes a system housing, a key identification system, a key cutting system, a key blank storage system, a key blank transfer assembly, and a duplicated key retrieval opening is disclosed. The key identification system may be housed at least partially within the system housing and is configured to identify a master key. The key blank storage system comprises a plurality of rods configured to removably couple to a plurality of key carriers. The key blank transfer assembly is housed within the housing is configured to remove one key carrier of the plurality of key carriers from the key blank storage system with the key retrieving apparatus and transport the one key carrier and the key blank coupled thereto from the key blank storage to the key cutting system. The duplicated key retrieval opening is positioned on the housing to receive the one key blank after the one key blank has been cut.
