It is easy to spend an absolute fortune on
locksmith courses, tools and materials so do your research and find the right education for you. Also do some ground work before you decide to begin a professional locksmith training course. Are there any locksmiths already working in your area and if so what other areas do they cover and what kind of locksmith are they? (domestic locksmith, auto locksmith, emergency locksmith, safe engineer).
You also need to decide if you want to become a locksmith for an existing company as an employee or if you want to set up your own locksmith business. If you decide to become an employee of an existing company then you may only need to be able to deal with certain types of locks. This means you could do a shorter and cheaper locksmith course that is tailored towards your specific needs.
