Key cutting is typically performed by professional locksmiths or key cutting specialists using various tools and techniques to ensure the accuracy and functionality of the new key.
Importance of key cutting
Key cutting is an essential service that plays a crucial role in ensuring the security and convenience of individuals. Whether it’s duplicating keys for family members or creating spare keys for emergencies, key cutting allows us to have reliable access to our homes, vehicles, and belongings. It also saves us from the hassle and expense of replacing an entire lock in case of a lost or damaged key.
Types of keys
Standard keys
Standard keys are the most common type of keys used in residential and commercial locks. They are typically flat and have a series of grooves or ridges on one or both sides. Standard keys can be easily duplicated using a key cutting machine and are widely available at hardware stores or locksmiths.
High-security keys
High-security keys are more advanced and offer enhanced protection against unauthorized duplication or tampering. These keys have complex designs and often incorporate features such as transponders, magnets, or special codes. High-security key cutting requires specialized equipment and expertise to ensure accuracy and maintain the security features of the key.
Transponder keys
Transponder keys are commonly used in modern cars and employ a technology that communicates with the car’s ignition system. The key contains a small electronic chip that emits a unique signal, allowing the car to start. Key cutting for transponder keys involves programming the chip and cutting the physical key to match the original.
Skeleton keys
Skeleton keys have a long history and were traditionally used to open multiple locks of similar design. They have a simple, basic shape and are often associated with antique locks. Skeleton key cutting involves replicating the shape and pattern of the original key to provide access to locks with similar mechanisms.
Tools and equipment used in key cutting
Key cutting machine
A key cutting machine is the primary tool used in key cutting. It is a specialized device that allows locksmiths to cut keys accurately and efficiently. Key cutting machines are equipped with cutting blades and other components that can replicate the unique grooves and ridges of a key onto a blank key.
Key blanks
Key blanks are pre-manufactured keys with a generic shape and size. They are used as a foundation for key cutting and can be cut and shaped to match different types of locks. Key blanks come in various designs and materials, depending on the type of key being cut.
Clamps
Clamps are used to hold the key blank securely in place during the cutting process. They ensure that the key remains steady and aligned with the cutting blade, preventing any errors or inaccuracies in the final key.
Calibration tools
Calibration tools are essential for ensuring the accuracy and precision of the key cutting machine. These tools allow locksmiths to make adjustments to the cutting blade, depth, and other settings to match the specific requirements of each key.
Step-by-step process of key cutting
1. Key identification
The first step in key cutting is identifying the type and design of the original key or lock. This helps determine the appropriate key blank and cutting techniques required to create an accurate duplicate.
2. Securing the key blank
The key blank is securely clamped into the key cutting machine using the appropriate clamps or fixtures. This ensures that the key remains stable and properly aligned throughout the cutting process.
3. Machine calibration
The key cutting machine is calibrated according to the specifications of the original key or lock. This involves adjusting the cutting blade, depth, and other settings to match the unique grooves and ridges of the original key.
4. Key cutting
With the machine calibrated, the locksmith proceeds to cut the key. The cutting blade carves out the desired pattern onto the key blank, replicating the grooves and ridges of the original key.
5. Checking the key’s functionality
Once the key cutting is complete, the locksmith tests the functionality of the new key. They insert it into the lock to ensure a smooth operation and proper alignment of the tumblers or pins within the lock mechanism.
6. Finishing touches
After confirming the key’s functionality, the locksmith may perform additional finishing touches to smooth out any rough edges or imperfections. This ensures that the key is aesthetically pleasing and comfortable to use.
Common techniques for key cutting
Manual key cutting
Manual key cutting refers to the traditional method of cutting keys by hand using basic tools such as files and cutters. While this method is time-consuming and requires a high level of skill and precision, it can be suitable for simple keys or situations where a key cutting machine is not available.
Automatic key cutting
Automatic key cutting involves the use of a key cutting machine that is powered by electricity or air pressure. This method enables locksmiths to cut keys more efficiently and accurately compared to manual cutting. Automatic key cutting machines often have advanced features and options for different key types and designs.
Computerized key cutting
Computerized key cutting is the most advanced and precise method of key cutting. It uses sophisticated software and digital machinery to replicate the unique specifications of a key. Computerized key cutting machines can store vast databases of key patterns and designs, making it quick and convenient to cut keys with complex or intricate designs.
Factors influencing key cutting
Key blank material
The material of the key blank can affect the ease of cutting and the durability of the final key. Key blanks are available in various materials such as brass, steel, and aluminum. Each material has its own characteristics, and locksmiths choose the appropriate blank material based on the requirements of the key and lock.
Key cutting machine capabilities
The capabilities and features of the key cutting machine can significantly impact the quality and accuracy of the key cutting process. Advanced machines with precise cutting blades and calibration options offer better results compared to basic machines with limited functionalities.
Expertise of the locksmith
The expertise and experience of the locksmith greatly influence the outcome of key cutting. A skilled locksmith can accurately identify key types, make necessary adjustments on the key cutting machine, and ensure the functionality of the new key. It is essential to choose a reputable and knowledgeable locksmith to guarantee a reliable and accurate key cutting service.
Key cutting for different types of locks
Padlocks
Key cutting for padlocks involves the duplication or creation of keys that match the unique pin tumbler or combination mechanisms of the padlock. The locksmith identifies the type of padlock and cuts the key accordingly, ensuring a secure and functional key for unlocking the padlock.
Deadbolts
Deadbolts are commonly found in residential doors and provide enhanced security. Key cutting for deadbolts requires precision to match the complex pin tumbler system within the lock. The locksmith carefully cuts the key to ensure a smooth operation and secure locking mechanism.

Incorrect key identification
A key cutting process begins with accurate identification of the original key or lock. Incorrect identification can result in the use of an inappropriate key blank or the application of incorrect cutting techniques, leading to an ineffective or non-functional duplicate key.
Key cutting machine errors
Key cutting machines are sophisticated tools, but they are not infallible. Errors in machine calibration, alignment, or blade quality can lead to inaccurate key duplication or damage to the key blank. Regular maintenance and calibration of key cutting machines are essential to minimize the risk of errors.
Lack of precision
Key cutting requires fine precision to replicate the unique grooves and ridges of the original key onto the key blank. Lack of precision can result in a key that does not fit or function correctly in the lock, causing frustration and inconvenience for the user.
Compatibility issues
Certain types of keys, such as high-security keys or keys with specialized transponder chips, may require specific key cutting techniques or equipment. Lack of compatibility between the key cutting machine and the key type can prevent accurate duplication or programming of these keys.
