Standard five-tumbler key locks are constructed of a variety of durable metals. Locks’ interior mechanisms are usually composed of brass or zinc die-casting. Steel or stainless steel is commonly used for the cam, which is the tongue that protrudes from the lock to secure it.

The process of making a key


Locks are categorized into three categories: low-security, medium-security, and high-security. Low-security locks are often composed of less expensive materials, and their components may be mass-produced.

A business that makes low-security locks could have two or three versions on the market. They maintain the parts needed to modify them in stock. Aside from low-security locks, the lock manufacturer is usually an original equipment manufacturer. That means that they build both the parts and the end products for their locks.

The solution is simple

The key is created initially in a normal five-tumbler key lock. The key blanks are purchased by the lock maker, who then cuts the ridges, or combinations, in each key. Each key features five bumps, each of which is sliced to a different degree. These levels are labeled with numbers. One is a low cut, two is next, and three is last. There are usually just four stages, while some manufacturers may utilize up to seven.

Mechanisms on the inside

After that, the internal mechanics are built. These were made to match this specific lock order, and the machinery used to create them may need to be retooled or reset.

Because the tiny internal elements, particularly the pins, must be fabricated to extremely tight tolerances. The machinists may conduct a test run before embarking on a large project. If required, the machines can then be reset.

Other components

The rest of the lock’s components are likewise made by the same company. Die-casting and subsequent machining are used to create the cylinder, or plug, into which the key inserts. As well as guard plates, washers, the bolt or cam, and the casing.


The locks are constructed by hand after all of the pieces are available. Lock technicians work at well-lit desks with a bin full of lock parts and a key on a stand in front of them. A skilled worker can tell the key’s combination merely by glancing at it. The worker then inserts the pins that correspond to the key’s combination into the lock’s plug, or cylinder.

Steps to Completion

When a lock is finished, the worker tests it using the key to ensure that it works. At this stage, it may be sent to a quality check station before being dusted or polished. Workers package and send the completed locks inboxes.

Quality Assurance

The most crucial component of quality control is ensuring that the small machined pieces are the exact sizes stipulated. When a new bespoke order is placed, the machinists normally create trial samples of the pieces. Although may then be physically examined and measured using accurate gauges.
