  • Publication number: 20140259582
    Abstract: A method and apparatus for replicating a transponder key is disclosed. The transponder replication device includes an antenna that reads a transponder code from a transponder key; a camera, wherein the camera captures a bitting characteristic of the transponder key blade; a stabilizer that secures the transponder key in place while the camera captures the bitting characteristic; a memory device for storing the transponder data; means for transmitting the transponder code and the bitting characteristic of the transponder key blade to a remote location; and, a remote communication device that is compatible with the internet communications device that receives the transponder data and transmits it to a transponder duplication device at the remote location.

  • Publication number: 20130152352
    Abstract: A method for coding a key and a female lock part for a lock in a lock system, whereby a blank is separated into two parts by a separating cut that is guided perpendicular to the longitudinal axis and in the direction of the longitudinal axis of the blank. The cut forms a coding contour. The two parts are then post-processed to form the key and the female lock part or serve as coding disks that are affixed to a key and a female lock part.

  • Publication number: 20100313618
    Abstract: A “minimalized” key has the smallest length, overall volume and weight commensurate with the ability to operate a lock in the same manner as a corresponding conventional key. It is easily formed from a conventional key blank, preferably after unique edge profiling to suit the lock, by eliminating the head portion and providing an aperture in the remaining body portion for attachment of means that facilitate application of a torque to turn it to operate the lock. Minimalized key blanks are also easily and inexpensively made from strip stock of rectangular cross-section of appropriate dimensions by forming longitudinal grooves and an aperture in selected lengths thereof, and the minimalized key blanks so formed are then individually profiled to make minimalized keys to fit specific locks. They may also be color-coded to make them visibly distinguishable from one another.

  • Publication number: 20090277239
    Abstract: A master key system and method for a reprogrammable lock cylinder with at least one first master pin and one second master pin. The first and second master pins have different bitting configurations. The master key system includes at least a first array of change key cuts corresponding to an input key bitting array and sequence of progression and at least two master key cuts corresponding to the input key bitting array and sequence of progression and each of the change key cuts. The system further comprises at least one master pin matrix including a master pin sequence for each change key cut and at least one rekey matrix including a rekey cut for each change key. Each master pin sequence represents a sequence of master pins configured to achieve the respective change key cut and the at least two master key cuts.
