High security door barrel installation

Standard Euro cylinders fitted in many uPVC and composite doors can be easily snapped, picked or drilled by intruders. Modern high-security barrels are designed to resist forced entry, offering advanced protection and long-lasting reliability. We install police-approved, anti-snap cylinders designed to break safely in a controlled way if attacked — keeping the locking mechanism secure and preventing access to your home.

Upgrading your cylinder is one of the quickest and most effective ways to improve door security without replacing the entire lock or door.

Why should I upgrade my door barrel?

Common reasons include:

  • Standard cylinders can snap in seconds during forced entry
  • Keys have become loose, worn or difficult to turn
  • Lost or stolen keys
  • Moving into a new property
  • Upgrading to insurance-approved security
  • Combining with a new 5-point mechanism
  • Peace of mind for families or vulnerable homeowners


A high-security cylinder dramatically improves the strength and performance of your door.
