High-security protection depends on the type of lock, cylinder and security hardware fitted to the property. Different products meet different standards and provide different security features.
BS3621 Locks are British Standard locks commonly used for mortice applications, including 5-lever mortice deadlocks and sashlocks.
TS007-rated Cylinders and Security Hardware are designed to meet enhanced security requirements for replacement cylinders and associated hardware, where the relevant product has the appropriate certification.
Anti-Snap Cylinders provide additional protection against lock-snapping attacks and may also incorporate anti-pick, anti-drill or anti-bump features, depending on the specific cylinder.
British Standard Night Latches and 5-lever mortice deadlocks are other security-focused options that may be suitable depending on the door, existing lock and property requirements.
Emergency Locksmith Ltd can assess the existing lock and recommend a suitable high-security upgrade based on the door type, existing hardware and any insurance requirements.
