Over the last few decades, changes in the locksmithing industry have changed drastically. Simple mechanical key duplication has grown into complex processes such as the manufacture of high-security automotive keys. As a result, modern locksmiths are required to perform more complicated jobs than ever. Traditional key cutting methods are not adequate to handle today’s demanding customers' needs. That is why CNC (Computer Numerical Control) key cutting machines are changing the locksmithing industry entirely by offering capabilities of precision, speed, and versatility that were previously unimaginable in key manufacturing.
CNC key cutting devices use digital control to produce very precise key cuts by employing very sophisticated software that determines how to cut the key so that it is accurate to within micrometers. The software used to control the machine provides very precise direction to the CNC key cutting device to replicate a wide variety of keys from standard mechanical keys to high-security automotive keys and everything in between, including laser cut and dimpled keys and keys with electronic components.
A CNC key cutting machine is a device that is controlled by a computer and is designed to create keys by utilizing computer-controlled motors and cutting tools. The computer software, which controls the CNC key cutting machine, receives input in the form of either a key code or a measurement of the original key, and then calculates the precise cutting path to replicate the key as closely as possible to the original key by providing very precise coordinates that the cutting head must follow.
In contrast to conventional mechanical key cutters that require both the skill of the operator and manual adjustments, a CNC key cutting machine automates the complete key cutting operation. By doing so, it significantly reduces the possibility of human error, increases the consistency of the key cuts, and allows locksmiths to complete their work much more efficiently. Numerous CNC key cutting machines have an array of key profiles stored in their databases, allowing users to generate new keys without having a physical template to replicate, offering added convenience in “all keys lost” scenarios.
CNC key cutting machines offer many benefits compared to traditional key cutting methods, which plays a big part in why CNC key cutting machines have become the standard key cutting method used by locksmiths today.
Precision is vital in the key cutting process, as the smallest amount of deviation from the cut could result in a key not working correctly and damaging the lock if it does not match the lock precisely. For this reason, CNC (computer numeric control) key cutting machines are used digitally when cutting keys to ensure that the cut corresponds to the cut from the original manufacturer.
In addition to using digital methods to cut keys, higher-end CNC key cutting machines can produce tolerances that vary from +/-1/1000 inch. Achieving such high tolerances and accuracy is very important for high-security automotive keys and dimple keys because even the slightest mistake could prevent a key from working. Additionally, because CNC key cutting machines remove all of the guesswork from the key cutting process, there is virtually no potential for making mistakes, improving customer satisfaction.
CNC key cutting machines can service a large variety of key types. A typical CNC key cutting machine is capable of cutting nearly all types of residential, commercial, automotive and high-security keys. Most cutting equipment can also cut tubular, sidewinder (laser cut) and dimple keys, which are rapidly becoming a new norm of key use for many new automobile makes and models.
The tremendous range of versatility offered by the CNC key cutting machine provides locksmiths with the ability to provide a wider selection of products and services to their customers without investing in numerous machines to perform the same tasks. With an effective machine, one CNC key cutting machine can provide most, if not all, key cutting requirements for a locksmith's work and allows a locksmith to save on costs and space in their work area.
One of the CNC key cutting machines’ revolutionary innovations is the ability of these machines to cut keys based on digital codes. Traditionally, when duplicating keys, you would need an original key to cut from; however, the CNC machines can create keys based solely on the vehicle or lock code.
The digital code access makes creating keys in “lost all your keys” situations very valuable. A locksmith can enter the key code into the unit, and by using the CNC key cutting machine system and software, the machine calculates where to make the cuts and creates a complete, operational key. This feature benefits locksmiths as it gives them the ability to produce locksmithing products that would typically be below standard or more expensive than what many people would pay for in a professional locksmith shop.
Automating many processes previously completed manually is one of the advantages of using CNC key cutting machines. The cutting, aligning, and measuring of depths are completed through digital controls, greatly reducing human error. Some CNC key cutting machines allow multiple cuts of keys to be done simultaneously or can even automatically switch between different types of keys when cutting.
With doing less manual work due to the increased automation with the CNC key cutting machines, a locksmith can provide better customer service, key programming, and do other high-demand, high-profit tasks while the CNC key cutting machine does all the precise cutting.
The majority of the current CNC key cutting machines can be easily integrated into key programming tools and databases. Locksmiths to gain remote access to auto-specific key code data, cut patterns and security features from the machine itself through connections to manufacturer or 3rd party databases ensures that they are cutting the latest model vehicles and cut security keys.
With real-time access to data, automotive locksmiths will be able to properly cut keys for all of the newest locking systems using the new technology in this field.
There are different configurations of CNC key cutting machines for different locksmithing needs.
Desktop CNC key cutters are small in size and typically designed for small locksmith shops, which makes them an excellent option. They are precise in their cuts and can cut many standard keys as well as automotive keys. They also fit in small areas and can produce the same high-quality end product as larger cutters.
Industrial-grade CNC key cutting machines are much larger than desktop units and designed for volume operation. They will have multiple cutting heads, advanced software features and usually support large key databases. These machines are primarily used by automotive dealerships, high-security key manufacturers and commercial locksmiths.
Portable CNC key cutting machines have become very popular with mobile locksmiths and are lightweight, portable and battery-operated, allowing them to cut keys at customer sites without sacrificing accuracy or performance. Although having a smaller frame, they possess many of the same advanced features: digital accuracy and cutting through coded files.
CNC key cutting machines serve multiple purposes in residential, commercial, and automotive locksmithing.
With the installation of new CNC machines, locksmiths can provide an accurate duplicate of standard and high-security keys with the ability to integrate code cutting and databases to help service clients who have a restricted or patented system of keying.
One area of locksmithing that is taking the most advantage of CNC technology is automotive locksmithing as many manufacturers are now using many different types of complicated keying systems, such as laser cut, dimpled and smart key systems. With the installation of CNC technology with the precision needed for creating these advanced types of keys, along with the code cutting feature on CNCs, they are an ideal progression for dealing with sophisticated automotive locking systems.
Some CNC machines have the ability to cut patented or restricted keys. This type of keying is especially important within government buildings, large corporations, and other secure areas due to the precision needed to stay within legal compliance.
CNC key cutting machines are the future of locksmithing. As locks and keys are becoming increasingly complicated, traditional methods of key production will not satisfy the demands of the industry. With the development of CNC technology, locksmiths will be able to maintain a competitive edge by offering their customers the highest levels of precision, automation and flexibility that are needed to support current systems and keep pace with future technology.
Emerging trends to watch for are the introduction of AI-assisted recognition of keys, the implementation of security cloud-based databases, and total integration with key programming products, thus creating a more efficient method of producing a key. All of these trends will solidify the credentials of CNC machine tools and allow locksmiths around the world to enhance their level of service and meet the ever-increasing demand for future locksmith services.
CNC key cutting machines are revolutionizing the locksmith industry through the combination of precision, automation, and versatility. They allow locksmiths to create keys for modern locks with maximum effectiveness and efficiency. Whether working with residential, commercial, or automotive applications, CNC machines will give locksmiths the tools they need to provide their customers with service and improve the operation of their business.
