Shane Wighton, the engineer behind the popular Works By Design channel, developed this innovative “unpickable” lock. Known for building complex mechanical systems, he set out to solve a long-standing problem in security: how to create a lock that a key can open but tools cannot. Traditional locks rely on pin tumbler mechanisms, which can often be manipulated with enough skill. His approach, however, was radically different, removing direct access to the internal mechanism altogether.
The lock uses a gear-driven system combined with an offset keyway design. When the key is inserted and rotated, the entire internal mechanism shifts behind a solid barrier, making it physically inaccessible to lockpicking tools. It also integrates magnetically controlled components, including a detachable key system that uses an ON/OFF magnetic switch inspired by industrial magnetic holders. Internally, hidden pins align only after a full rotational sequence, and a specialized “lockout pin” detects sudden movement or impact, instantly freezing the mechanism to prevent forced entry. This multi-layered design ensures that even if someone understands the system, they still cannot physically interact with it.
Despite its breakthrough concept, experts emphasize that no lock is truly unpickable in absolute terms. Techniques like impressioning, where a blank key is shaped based on internal marks, could still pose a challenge, and strong external magnetic fields might interfere with certain components. Still, the project represents a major shift in security engineering, focusing not on resisting attacks, but on eliminating access entirely. Currently being tested by professional locksmiths and lockpicking communities, this design stands as one of the most creative attempts yet to redefine how mechanical security works.
