We’re experts in home security, and we want to share our tips to keep your home safe from lock snapping. Stick with us as we explain how it works and what you can do to stop it. Let’s make sure your home stays safe and sound.

What is Lock Snapping?

Lock snapping is a technique used by burglars to gain unauthorised entry into a property by exploiting vulnerabilities found in certain euro cylinder locks. Essentially, lock snapping involves breaking the euro cylinder lock mechanism to manipulate it and unlock the door. This method capitalises on the inherent weakness of low-quality euro cylinder locks, particularly those often installed in UPVC, composite, and wooden doors.

We tend to see locks as the gatekeeper of our home, the very thing that prevents entry to those pesky burglars. Unfortunately, it’s often the weakest link in the chain. Burglars take advantage of this vulnerability by applying force to the lock, causing it to snap and rendering it ineffective. Even multi-locking points can’t save you, as these all depend on the cylinder to open!


What makes lock snapping particularly concerning is its simplicity and relative speed. Unlike more sophisticated burglary techniques that require specialised tools or extensive knowledge, lock snapping can be executed using minimal force and basic household items. This accessibility makes it a preferred method among thieves seeking quick and discreet entry into homes.

In essence, lock snapping exploits a fundamental flaw in traditional lock systems, highlighting the importance of upgrading to more secure alternatives. By understanding the mechanics of lock snapping and taking proactive measures to reinforce your home’s security, you can effectively deter burglars and protect your property from unauthorised access.

Am I at risk of lock snapping?

Euro cylinder locks are a popular choice for securing UPVC, composite, and wooden doors in both residential and commercial settings, meaning you probably have one!

UPVC doors, often found in homes and businesses alike, frequently feature euro cylinder locks due to their affordability and ease of installation. Similarly, composite, and wooden doors commonly utilise euro cylinder locks for their convenience and compatibility with various door designs.

Unfortunately, the widespread use of euro cylinder locks also makes properties susceptible to lock snapping attacks. Burglars are aware of this vulnerability and may specifically target homes and businesses with these types of locks.

To determine if your property is at risk, it’s essential to understand the signs of an at-risk euro cylinder lock and assess its security features.

Identifying at-risk Euro Cylinder Locks

Euro cylinder locks are characterized by their long cylindrical shape with a keyhole in the middle. If your door features this type of lock, it’s crucial to determine whether it has adequate protection against lock snapping.

Is the lock protruding from the door, does it have visible screws? If so, your lock could be at risk from lock snapping.

Preventive Measures

  1. Anti-Snap Lock Installation

Fitting an anti-snap euro cylinder lock is one of the most effective ways to prevent lock snapping. These locks, tested and approved to standards such as SS312 Diamond or TS007 3*, provide robust protection against burglary attempts. Ensure the lock is installed correctly by consulting a licensed locksmith.

  1. Standard Euro Cylinder Lock Selection

When choosing a euro cylinder lock, opt for models that meet recognized standards for snap resistance. Sold Secure Diamond approved cylinders and TS007 3-star Kitemark locks are recommended for enhanced security. Additionally, consider pairing a 1-star kitemark cylinder with 2-star door furniture for added protection.

  1. Professional Installation

Proper fitting of the lock cylinder is essential to its effectiveness. Ensure that the lock protrudes no more than 3mm from the handle and is flush with the door surface. Hiring a qualified locksmith is crucial to selecting the correct size lock and ensuring it is installed correctly.

Protecting your home against lock snapping requires proactive measures to fortify your door security. By understanding the risks associated with this burglary method and implementing preventive strategies such as installing anti-snap locks and adhering to standard guidelines, you can safeguard your property effectively. Don’t leave your home vulnerable to opportunistic thieves—take action to secure your peace of mind and protect your loved ones and belongings.
