School
The good news is you don’t really need a degree to become a locksmith. Locksmith training is generally received by way of a training program or an apprenticeship. The latter may not be paid, depending on the locksmith you’re working under but does provide you valuable information on a career that probably isn’t offered in a formal situation. You will need either this or the training program to learn the basics of locksmithing; lockpicking, lock repairs, the basic mechanisms of locks and making keys. Of course it helps to have some fair amount of dexterity, hand to eye coordination and some mechanical aptitude.
