Locksmithing is the work of creating and bypassing locks. Locksmithing is a traditional trade and in many countries requires completion of an apprenticeship. The level of formal education legally required varies by country, ranging from no formal education to a training certificate awarded by an employer, or a full diploma from an engineering college, along with time spent as an apprentice.
