Identifying Key Blanks: A Comprehensive Guide
Locksmiths and key enthusiasts often find themselves in a situation where they need to identify the correct key blank for a core or cylinder. The process can be confusing, especially when faced with unfamiliar keyways. However, with some helpful tips and an understanding of key blank directories, you can easily determine which key blank you need.
In this article, we will discuss the importance of correctly identifying key blanks and provide a step-by-step guide to help you through the process. From understanding groove angles to categorizing keyways, we will cover everything you need to know to make accurate identifications.
2. The Importance of Identifying Key Blanks
Identifying the correct key blank is crucial for locksmiths and anyone working with locks. Using the wrong key blank can lead to wasted time, ineffective solutions, and unsatisfied customers. By being able to confidently determine which key blank to use, you can streamline your work and ensure customer satisfaction.
3. Using Key Blank Directories
One of the first tools you'll need to successfully identify key blanks is a key blank directory. These directories, such as the Ilco book or the JMA book, provide detailed information about different key blanks and their corresponding keyways. By familiarizing yourself with these directories, you gain access to a wealth of knowledge that will assist you in your identifications.
4. Understanding Groove Angles
When looking at key blank directories, it's essential to understand how groove angles are represented. Many people mistakenly compare the groove in the picture to the groove they see in the actual keyway. However, key blank directories display the groove as it would look if the key were placed on the profile of the cylinder. This understanding is crucial for accurate identifications.
5. Identifying Key Blanks for SFIC Cylinders
SFIC (Small Format Interchangeable Core) cylinders can be particularly challenging to identify due to their complex keyways. However, the principles we will discuss can be applied to any type of keyway. By following the steps outlined in this article, you will gain confidence in identifying key blanks for SFIC cylinders and other types of locks.
6. Using the Top Right Groove Angle
To simplify the identification process, we recommend focusing on the top right groove angle of the key blank. By using this angle as a reference point, you can quickly narrow down your options and eliminate key blanks that do not match the profile you see in the keyway.
7. Categorizing Angles: Major, Minor, and Flat
To further categorize keyway angles, it can be helpful to divide them into three categories: major angles, minor angles, and flat angles. Although this categorization is not an exact science, it provides a useful starting point for identification. By recognizing the characteristics of each angle category, you can eliminate key blanks that do not fit the profile you are examining.
8. Narrowing Down Keyways
As you examine the key blank's profile, you can begin to narrow down your options by comparing the angles and grooves you see. By carefully observing the differences and similarities, you can start to eliminate key blanks that do not match the keyway in question. This iterative process allows you to progressively narrow down the possibilities.
9. Examining Gap Differences
Another crucial aspect to consider is the gap at the bottom of the keyway. By comparing the gaps between the key blank and the keyway's profile, you can gather additional information to aid in your identification. The size and shape of the gap can provide valuable clues that help differentiate between similar keyways.
10. Applying the Principles to Different Keyways
While we have focused on SFIC keyways in our examples, the principles we have discussed apply to all types of keyways. Whether you are working on a standard lock cylinder or a specialized keyway, using the same methodology will allow you to identify the correct key blank with confidence.
Identifying key blanks is a crucial skill for locksmiths and key enthusiasts. By understanding the principles outlined in this article and utilizing key blank directories, you can confidently determine which key blank matches a particular keyway. With practice and experience, you will become proficient in identifying key blanks, saving time and ensuring customer satisfaction.
