Abstract

An apparatus and system facilitates the identification of a key and its corresponding lock by marking each key with a unique indicia element that has a unique set of indicia. The indicia is easily recognized by a computing device using an image recognition process, and can map the unique indicia into a corresponding unique identifier to create a record that correlates the key with a specific lock, indicating the lock'"'"'s location and other information about the lock. A user, given a key with indicia element on it, can then determine the lock to which the key corresponds by the indicia being automatically recognized, and used to locate a record corresponding to the indicia, and presenting the information in the record to the user.
