In Norway, it is legal to own and use lockpicking tools. However, it is illegal to use them on property or locks that belong to others without permission (cf. Penal Code §§ 321 and 346). Lockpicking is not a criminal activity—as long as it is practiced within the boundaries of the law. 

Lockpicking is, in practice, the act of unlocking a lock by manipulating its internal components without using the original key.

Although lockpicking is sometimes associated with criminal intent, it is a legitimate skill within the locksmith profession, and is also pursued by law-abiding citizens as a useful skill to learn—or simply as a hobby known as locksport. There is no established Norwegian term for locksport, but a direct translation would be låssport.

Locksport is a growing, well-organized, and respected hobby with a competitive edge in the United States. TOOOL (The Open Organisation Of Lockpickers) has local chapters in over 20 states and hosts workshops and competitions. Locksport International, founded in 2005, helped establish the term locksport as a recreational and competitive activity. Many practitioners see it as a way to improve physical security by exposing vulnerabilities.

Locksport is essentially the practice of lockpicking as a technical hobby—for learning and mastery, not for professional use or unethical activity. Enthusiasts develop a range of skills including picking, bumping, and bypass techniques that have traditionally been reserved for locksmiths and security professionals. Practitioners appreciate the challenge and excitement of learning to open different types of locks, and often gather in groups to share knowledge, exchange ideas, and participate in recreational activities and competitions.

The Two Core Rules of Locksport:
1. Never pick a lock that you do not own or do not have explicit permission to pick.
2. Do not pick locks that are in use or that you rely on for security.
