Tubular cylinder locks are a specific type of lock commonly found in various applications, from vending machines to some residential and commercial doors. As a supplier of cylinder locks, I've received numerous inquiries about the ease of picking these tubular cylinder locks. In this blog, I'll delve into the science behind tubular cylinder locks, analyze their pick - resistance, and provide insights for those considering using them.

How Tubular Cylinder Locks Work

To understand whether tubular cylinder locks are easy to pick, we first need to grasp how they function. A tubular cylinder lock consists of a circular keyway with a series of pins arranged in a circular pattern around the center. The key is also tubular in shape, with ridges that correspond to the correct height of each pin. When the key is inserted into the lock, the ridges align the pins at the shear line, allowing the plug inside the lock to rotate and unlock the mechanism.

The design of tubular cylinder locks is based on the principle of pin - tumbler locks. However, unlike traditional pin - tumbler locks with a linear arrangement of pins, tubular locks have a more complex circular configuration. This circular design offers some unique advantages in terms of security and functionality.

Factors Affecting the Ease of Picking

  1. Pin Complexity
    The number and arrangement of pins in a tubular cylinder lock play a crucial role in its pick - resistance. Locks with a larger number of pins generally offer more security. For example, a tubular lock with 7 or 8 pins will have a greater number of possible key combinations compared to a lock with 5 or 6 pins. A higher number of pins means that it is more difficult for a picker to find the correct combination to align all the pins at the shear line.
  2. Keyway Design
    The design of the keyway can also impact the ease of picking. Some tubular cylinder locks have a more intricate keyway design, which can make it harder for a picker to insert and manipulate picking tools. For instance, locks with a narrower or more irregular keyway may require specialized picking tools and more skill to pick successfully.
  3. Lock Quality
    The quality of the materials and manufacturing process used in the production of the lock is another important factor. High - quality tubular cylinder locks are made from durable materials that can withstand the forces applied during picking attempts. Additionally, precise manufacturing ensures that the pins and other components fit together tightly, making it more difficult for a picker to move the pins out of place.

Are Tubular Cylinder Locks Easy to Pick?

The answer to whether tubular cylinder locks are easy to pick is not straightforward. For an experienced and skilled locksmith or lock picker, some tubular cylinder locks can be picked relatively quickly. With the right tools and techniques, such as a tubular lock pick gun or a set of specialized picks, a picker can attempt to align the pins and open the lock.

However, it's important to note that not all tubular cylinder locks are equally easy to pick. As mentioned earlier, locks with a higher number of pins, a more complex keyway design, and better - quality construction are generally more resistant to picking. For example, our Cylinder Lock 70mm is designed with a sufficient number of pins and a well - crafted keyway to enhance its security.

In addition, modern tubular cylinder locks often incorporate anti - pick features. These features can include hardened steel pins, anti - bumping mechanisms, and other security enhancements that make it more challenging for a picker to gain access. Our Cylinder Lock 70mm also benefits from these advanced security features, providing reliable protection against unauthorized access.

Real - World Applications and Security Considerations

In real - world applications, tubular cylinder locks are used in a wide range of settings. In vending machines, for example, they are used to protect the contents and prevent unauthorized access. In this case, the lock needs to be secure enough to deter casual thieves but also easy to use for authorized personnel.

In residential and commercial settings, tubular cylinder locks can be used on doors and cabinets. When choosing a tubular cylinder lock for these applications, it's important to consider the level of security required. For high - security areas, such as banks or jewelry stores, more advanced and pick - resistant locks may be necessary. On the other hand, for less - sensitive areas, a standard tubular cylinder lock may be sufficient.

Tips for Choosing a Secure Tubular Cylinder Lock

  1. Check the Pin Count
    As discussed earlier, locks with a higher number of pins offer more security. Look for locks with at least 7 or 8 pins.
  2. Consider the Keyway Design
    Choose a lock with a complex keyway design that is difficult to access with standard picking tools.
  3. Look for Anti - Pick Features
    Locks with anti - pick features, such as hardened steel pins and anti - bumping mechanisms, provide an extra layer of security.
  4. Choose a Reputable Supplier
    Buying from a reputable supplier, like us, ensures that you get a high - quality lock that has been tested for security and durability.

Conclusion

In conclusion, whether tubular cylinder locks are easy to pick depends on several factors, including the lock's design, the number of pins, the keyway design, and the presence of anti - pick features. While some tubular cylinder locks can be picked by skilled individuals, modern locks with advanced security features offer a high level of protection.
