Why Choose Our High Security Door Locks?
TS007 3-Star & Anti-Snap Euro Cylinders
Featuring leading brands such as Avocet ABS and Yale Euro Cylinders, our anti-snap cylinders are engineered to resist lock snapping, picking, drilling, and bumping — common methods used in UK break-ins.
BS3621 Insurance-Approved Sashlocks
Ideal for timber doors, these mortice locks meet British Standard BS3621 requirements and are widely recognised by UK insurers.
Thumb-Turn & Keyed-Alike Options
Choose convenient thumb-turn locks for emergency exit access or keyed-alike cylinders to operate multiple doors with one key — ideal for homes, HMOs, and rental properties.
Centre-Case Gearbox Replacements
Restore multi-point locking systems without replacing the entire mechanism — a cost-effective solution for faulty or worn gearboxes.
Front Door Locks for UK Homes
Most UK front doors require a TS007 3-Star euro cylinder or BS3621-rated mortice lock to meet insurance and security standards. If your current lock is older than 5–7 years or lacks anti-snap protection, upgrading can significantly improve your home’s resistance to forced entry.
Our high security front door locks are suitable for:
-
uPVC doors
-
Composite doors
-
Timber front doors
-
Patio and back doors
-
Rental properties and HMOs
