A cover for a key is disclosed. The cover includes: a first wall; a second wall opposite to the first wall; and an outer wall extending between the first wall and the second wall, the outer wall defining a pair of slots extending therethrough, the slots being positioned opposite to each other on the outer wall, wherein the first wall, the second wall, and the outer wall define a closed chamber for receiving a bow of the key and an opening to the chamber.

A security device for an item of merchandise is provided. The security device includes a non-programmable locking mechanism comprising a mechanical lock and a programmable locking mechanism comprising a monitoring circuit operatively coupled to an alarm. The security device is configured to secure an item of merchandise from theft or removal when the mechanical lock is locked and to be separated from the item of merchandise when the mechanical lock is unlocked. The alarm is configured to provide an alarm signal if the security device is separated from the item of merchandise while the monitoring circuit is armed.

Magnetic keys, bow caps and key components are described. In one aspect, the present application describes a key. The key includes a blade and a bow connected to the blade. The bow is for applying torque to the blade. The bow defines a key ring aperture located near a top of the bow. The top is the portion of the bow furthest from the blade. The key also include a magnet fixedly coupled to the bow by placement within the key ring aperture to provide a magnetic field on at least one side of the key.

A lock key comprising of (3) pieces. A head, a key blade and a snap lock. These pieces are interlocked together, so that separation is not possible in normal usage. The head is made of precious metal or non precious metal set with or without stones and may consist of various esthetic and ornamental forms. The snap lock engages the head and the key blade in a way to inhibit the removal of the head from the key blade in normal use. The key blade can be easily removed from the head and exchanged with another key blade as needed.

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.
