Abstract: The Key Identification System enables a key to be quickly and easily related to a object/structure/item. It accomplishes this by having the key manufactured in a way to have the head/bow take on the appearance/shape of the object/structure/item that the key will be opening. It will NOT have the appearance/shape of a door/lid or lock because the door/lid and lock are not a distinguishable part of the object/structure/item that the key is used for. So therefore a key that opens the front door of a house is in the appearance/shape of a house, the key that opens a car is in the appearance/shape of a car and so on.

Abstract: An identification system utilizes a plastic housing which is appropriately sized to hold either a key or a coin as well as an information sheet on which the user may place selected indicia referring to the key or to himself. Each embodiment utilizes a living hinge closure attachment to secure the key or coin and information sheet within the housing. Utilizing the housing and indicia for identifying the key minimizes the excess material and connections thereby simplifying the identification and storage problem, yet because the use of the housing with the key slightly increases the size of the key head, it provides a slightly greater moment arm for turning the key in a lock and gives a slightly larger gripping surface to be employed when so turning the key. These factors are significant when dealing with children and with elderly people who may not have the physical strength and dexterity required for some small headed keys.

Abstract: A code locking mechanism that transmits information between a key and a locking mechanism secured against interception misuse, but flexible with respect to original equipment, replacement parts, and emergency functions, is obtained if the key code is, in each case, cryptographically encoded through a hardware encoder. When the locking mechanism is first operated, a control element, inductively coupled to a locking mechanism read-write unit with a new key once and in a non-overwritable manner, transmits an indent number to the object memory. Object-specific identity data are also stored in the control element. With the latter, a key number from a key register of the control element is combined with the key code to read the latter together with a roll-in random code into the set of first still-neutral keys and into the object memory. Thus, a key is valid only if the object-specific identity data are taken into account in its key code.

Abstract: An identification system utilizes a plastic housing which is appropriately sized to hold either a key or a coin as well as an information sheet on which the user may place selected indicia referring to the key or to himself. Each embodiment utilizes a living hinge closure attachment to secure the key or coin and information sheet within the housing. Utilizing the housing as the indicia for identifying the key minimizes the excess material and connections thereby simplifying the identification and storage problem, yet because the use of the housing with the key slightly increases the size of the key head, it provides a slightly greater moment arm for turning the key in a lock and gives a slightly larger gripping surface to be employed when so turning the key. These factors are significant when dealing with children and with elderly people who may not have the physical strength and dexterity required for some small headed keys.
