Today some countries require apprenticeships for workers trained in the trade while others require certifications to qualify for the title of Master Locksmith. There are even countries that grant diplomas in Engineering to locksmiths educated in this field.

Locksmiths vary in their skills and may specialize in different aspects of the trade. Some operate out of a shop offering key duplicating or changing locks. Their services include installing dead bolt locks, home safes, window locks or entry door access systems.

Others may concentrate on specific areas such as security systems adapted for automobiles or safes which provide a combination of locks with alarm systems.

Some locksmiths are security consultants offering customers a comprehensive assessment of their security needs and applying the most efficient system to meet their requirements. They specialize in complex master key systems for full buildings or biometric access to institutions.

If we look around in our everyday life we are surrounded by security systems of all manners. Our home may have a security system which we access with a digital code or allow a visitor to enter after we have seen him on a video from the lobby and can buzz open the door.

We may work in an institution where the entry is allowed only by finger or hand touch. Our automobile is operated by a coded key and we draw money from the bank with a secured card and code. Jewelry, documents and other valuables are protected in either home or bank safes.
