The lock as a way of securing property is about 4,000 years old. Originally, we - locksmiths - used to make the entire lock including hand cutting each screw. Now it’s about intricate repairs and renovations, determining risk levels at a property and designing and installing appropriate combinations of equipment to deny access to a thief or threat. This includes the design, implementation and management of commercial locking and key control systems.

There are dozens of different lock types, including electrical, mechatronic, and mechanical. In fact, the mechanical versions such as the cylinder lock, the mortice lock, and the disc tumbler remain equally effective in the right circumstances and – as industry research shows - always will. For example: a disc tumbler lock is a lock made of slotted rotating detainer discs. A specially cut key rotates these discs until the slots are aligned. The advantage of this mechanism is that it does not use springs and so can’t be bumped to force it open, but it also means that bad weather doesn’t affect the lock as much. This is particularly useful in environments which would damage normally ultra-reliable types of locks such as anything to do with the sea/ marine.

Mechatronics is relatively new. This introduces an encrypted electronic element. Therefore, this cannot be copied, either by normal means or by 3D printing. Remarkably clever.
