The present invention addresses the problem of providing a key that allows key number information to be changed or added and that allows key information to be easily read. A key 1 has a key body 2 and key information 3 displayed on the surface of the key body 2. The key information 3 is a two-dimensional code 30 that can be read by a reading device. The two-dimensional code 30 is preferably displayed on a flat surface of the key body. The key body 2 has a tip end 2a that can be inserted into a lock and a base end 2b on the side opposite the tip end 2a; and the two-dimensional code 30 is preferably located on the base end 2b side and displayed on a flat base end surface 23 that extends in a direction Z that intersects the direction connecting the tip end 2a and the base end 2b.

The utility model belongs to the technical field of key protection shells, and particularly relates to an anti-falling type automobile intelligent key shell which comprises a protection sleeve and a key area on the protection sleeve, a square groove is formed in one side of the protection sleeve, a protection pad is fixedly connected to the protection sleeve, a female buckle is installed at one end of the protection pad, and a male buckle is installed at the other end of the protection pad. A male buckle is fixedly installed on the protective sleeve, and the protective pad covers the square groove through the female buckle and the male buckle. According to the automobile intelligent key protection sleeve, the protection pad is arranged to protect a spare key, the spare key on one side of an automobile intelligent key is located in the square groove, then the female buckle is pulled to be separated from the male buckle, shielding of the protection pad on the square groove is removed, the spare key is exposed, and then the spare key is popped out of the protection sleeve through the pressing head to be used. After use, the spare key is taken back, the protective pad shields the spare key through connection of the female buckle and the male buckle, operation is easy and convenient, the spare key is prevented from being abraded and collided, and meanwhile the overall attractiveness is improved.

The invention relates to an auxiliary key unlocking device and an unlocking method thereof.The auxiliary key unlocking device comprises a main supporting frame, a rotary supporting rod and a key fixing piece, the rotary supporting rod is rotationally installed in the middle of the main supporting frame and is integrally arranged in a Z shape, and the outer end of the rotary supporting rod is located on the outer side of the main supporting frame; the inner end of the rotating supporting rod is located on the inner side of the main supporting frame, and a key fixing piece used for clamping a key is installed at the inner end of the rotating supporting rod. The intelligent lock has the advantages that the problems that a traditional unlocking mode is low in efficiency, large in labor consumption, poor in adaptability and the like are effectively solved, and the intelligent lock has functionality, reliability and economical efficiency and has remarkable practical value; an operator does not need to excessively approach the power distribution cabinet or adopt a dangerous posture, so that potential safety hazards such as collision and slipping caused by limited space are reduced; the whole structure is simple, parts are designed in a modularized mode, disassembly and maintenance are convenient, no complex electronic elements exist, durability is high, and long-term use cost is low.

A securement device is provided. The securement device comprising: a ring comprising coplanar facing ends separated by a space; and a housing, a lock member positioned at least partially within the housing, wherein the lock member comprises a neck having a width less than the space, and a body having at least a portion with a width greater than the space; wherein the article is configured to adjust from a locked configuration to an unlocked configuration; the locked configuration preventing rotational translation of the ring through the housing; and the unlocked configuration allowing rotational translation of the ring through the housing.

A key plug rotatable within a cylindrical bore of a cylinder lock. An upper relatively narrow part of a key way has a small lateral width no more than 33% of the maximum width of a lower relatively wide part of the keyway and extends obliquely upwards along a first direction pointing away from a second lower side wall of a lower part and being inclined at a relatively small angle α, in the interval 3° to 12°, relative to the vertical mid-plane. The sideways or lateral location of the upper relatively narrow part of the keyway is such that an imaginary downward extension thereof, substantially in a second direction opposite to the first direction down to an outer cylindrical contour of the key plug, will fall onto the outer cylindrical contour at a same second side of the vertical mid-plane and inside the second lower side wall of the keyway.
