The Science of Lock Picking: A UK Guide to Prevention

Startling Facts: The Reality of Lock-Picking Beyond Hollywood

Did you know that 8.32% of burglaries in the UK in 2019 involved lock snapping? Lock snapping is a burglary technique where the intruder applies force to snap a cylinder lock at its weakest point, usually the central screw hole. Once the lock is snapped, the intruder can easily manipulate the lock mechanism to open the door. It’s a quick and relatively quiet way to gain entry, making it a popular choice among burglars. In this guide, we’ll explore the intricate science of lock-picking, its legal ramifications in the UK, and how you can safeguard against it.

The Anatomy of Locks: Understanding Vulnerabilities

The Inner Workings

A lock is a marvel of engineering, designed to secure your belongings. It comprises various components—pins, tumblers, and springs—that work in harmony. Understanding this anatomy can help you appreciate the vulnerabilities that skilled lock-pickers exploit.


The material of a lock plays a crucial role in its susceptibility to picking. Brass locks are easier to pick due to their softer composition, while steel locks offer more resistance but can be susceptible to rust.

Type of Locks Commonly Used in the UK

Padlocks: Convenient but Risky

Padlocks are portable and easy to use but often lack the security features needed to deter skilled lock-pickers. They are often used for securing sheds, gates, and lockers. However, they can be easily compromised using basic lock-picking tools or techniques like shimming, which involves inserting a thin piece of metal to disengage the lock.

Deadbolts: The Gold Standard

Deadbolts are renowned for their robustness and are a common choice for securing homes. They are difficult to pick and offer resistance against forced entry methods such as kicking or prying. For optimal security, consider installing a double-cylinder deadbolt.

The Art and Science of Lock-Picking

Common Techniques: Raking, Bumping, and Single-Pin Picking

These are some of the most common techniques used by both locksmiths and criminals. Raking involves rapidly moving a rake pick in and out of the lock to set the pins. Bumping uses a special key to apply force and align the pins. Single-Pin Picking is the most precise method, requiring skill and patience.

Tools of the Trade: From Tension Wrenches to Pick Guns

Lock-pickers often use specialised tools like tension wrenches for applying pressure and pick guns for rapid pin movement. Knowing these tools can help you understand how your lock can be compromised.

Countermeasures: Safeguarding Your Security

High-Security Locks: An Investment in Peace of Mind

Consider upgrading to high-security locks made of composite materials that are both pick and drill-resistant.

Additional Security Measures: Cameras and More

Installing security cameras and motion sensors can act as a secondary line of defence, deterring would-be lock-pickers.

UK-Specific Legal Landscape: What You Need to Know

Carrying lock-picking tools in public without a valid reason is illegal under the Theft Act 1968. This law makes “going equipped” for theft or burglary a criminal offence, underscoring the importance of relying on professional locksmith services.

Conclusion: Knowledge is Your Best Defence, Action is Your Safeguard

Understanding the science and legality of lock-picking is crucial, but taking proactive steps is equally important. Don’t underestimate the value of knowledge; it’s your most potent weapon against this real-world threat.

Quick Summary: Actionable Steps to Protect Yourself

  1. Choose the Right Material: Opt for steel locks over brass for better resistance against picking.
  2. Select High-Security Locks: Deadbolts are generally more secure than padlocks. Consider locks that are both pick and drill-resistant.
  3. Be Aware of Tools: Knowing what tools lock-pickers use can help you understand how to better secure your locks.
  4. Invest in Additional Security: Install security cameras and motion sensors as a secondary line of defence.
