The present invention relates to a changeable combined mechanical key, belonging to the technical field of key structures of encryption locks. The changeable combined mechanical key includes a bracket detachably connected to an end of a key handle, and a protective cover detachably connected to the end of the key handle and a key-shaped component. The present invention achieves anti-theft and duplication-preventing purposes for a key, and has unique advantages in many important fields such as safety boxes, important military places, banks, household intelligent anti-theft locks, and any other fields that require secrecy security. Unlike an electronic key that is easy to cause a problem due to an electronic circuit device and software and so on, the present invention, which is irreplaceable and has changed a machining process of a traditional mechanical key, saves energy and reduces consumption, and has a broad application prospect.

Some of the inventive concepts described herein include a data key having a computer readable medium containing information indicative of a bitting pattern for a master key. The bitting pattern on the data key may be downloadable to a key cutting device to cut a duplicate key that has the same bitting pattern as the master key. In addition, a method of creating a data key is also provided herein. The method includes identifying a type of key; identifying a bitting pattern; and storing the type of key blank required and bitting pattern to be cut in the key blank on a computer readable medium.

Embodiments disclosed herein can include one or more labels, each label having an indicia receiving surface adapted to receive indicium or indicia. The indicia receiving surface can provide a permanent, durable writing surface. A key for operating a mechanical lock can include one or more labels. The key can include a key main body and at least one label coupled to the key main body. The key main body comprises a head and an elongate body coupled to the head. The elongate body is configured to physically engage and operate a lock, such as a mechanical lock. The label can define an indicia receiving surface adapted to receive indicium or indicia.

A lockable wagering chip container is disclosed which includes a case, a drawer, and a lock mechanism. The case includes a case top, a case bottom, two case sides, and two case ends. The case top includes a through-hole and at least one of the two case ends is open. The drawer includes a drawer top, a drawer bottom, two drawer sides, and two drawer ends. The drawer bottom, two drawer sides, and two drawer ends partially enclose a drawer interior configured to hold a plurality of chips; the drawer top is open. At least one of the drawer ends includes a chip slot configured to accept a chip inserted when the drawer is in a closed position. The lock mechanism is positioned within the case and configured to secure the drawer in the closed position until the lock mechanism is released by a key inserted into the through-hole.

A method of identifying a specific key amongst a bundle of keys requires a plurality of keyhole tags and a plurality of key sleeves. Each of the keyhole tags includes a wireless transmitter. Each of the key sleeves includes a wireless receiver and at least one notification device that is associated to a corresponding tag. The method begins by broadcasting an identification signal with the wireless transmitter for each of the plurality of keyhole tags. The method then positions the plurality of key sleeves adjacent to a desired tag from the plurality of keyhole tags. The method then receives the identification signal for the desired tag with the wireless receiver for each of the plurality of key sleeves. Finally, the method actuates the notification device of a specific sleeve from the plurality of key sleeves, if the corresponding tag for the specific sleeve is the desired tag.

The present disclosure provides mates keys and mates key bows having respective mating surfaces disposed on respective bows, as well as sets of keys configured to physically mate with one another by way of respective mating surfaces defined on respective bows of the keys. Each of the mates keys comprises a blade portion, which may be bitted to match a given lock, and a bow portion attached to the blade portion which can be mated to a bow portion of another mates key. When physically mated, the bow portions of two or more keys are physically fitted together to form a visual based on respective visuals on the mates key bows.
