The Associated Locksmiths of America, Inc. (ALOA) is an international association comprised of qualified locksmiths and security experts representing the highest level of professionalism, experience and trusted reliability within the locksmith industry. Representing more than 10,000 locksmiths and associate members worldwide, ALOA ensures each member receives certification in accordance with their demonstrated experience. Traditionally, on-the-job training has been a primary method of learning locksmithing skills. Trainees work with experienced locksmiths until they have mastered the necessary skills. In some on-the-job training programs, employees attend demonstrations or receive classroom as well as practical training. The length of time necessary to complete on-the-job training ranges from three months to four years, depending on the level of expertise required for a given sector of the profession. Completion of courses at a locksmithing school will provide a basic knowledge of the trade and may shorten the length of the on-the-job training programs. Continuing education for the locksmith is provided by seminars and classes presented by lock manufacturers, locksmithing schools and locksmith associations, including the Associated Locksmiths of America.
