Euro Cylinder Locks for Every Door Type

Euro cylinder locks are the most common door lock type used in uPVC, composite and wooden doors across the UK. Our range includes standard euro cylinders, anti-snap 3-Star TS007 cylinders, thumb-turn options, and keyed-alike sets for multi-door convenience. Whether upgrading home security or replacing a worn lock, you’ll find a reliable cylinder in the correct size and security grade.

Why Choose Our Euro Cylinders?

Standardised Design & Easy Replacement
These cylinders are built to European EN standards, making them interchangeable across most uPVC, timber, and composite doors. Replacement requires just one screw and a simple swap—no need to replace the entire lock mechanism.
Wide Range of Styles
Select from:
- Double (Key Both Sides) Cylinders—ideal for standard residential entry doors
- Thumbturn Cylinders—key on the outside, turn knob inside for quick exit
- Half Cylinders—key only on one side, perfect for garages or utility spaces
Modular & Secure
These locks use standard pin-tumbler mechanisms and higher-pin designs (5–6 pins) for enhanced security. Anti-snap, anti-bump, anti-drill, and anti-pick variants are available to deter forced entry.
Custom Sized for Your Door
Available in multiple lengths (60mm to 90mm and above), ensuring a perfect fit for varying door thicknesses. Easy to measure and swap for a precise, flush finish.
Many of our high-security cylinders meet TS007 3-Star or Sold Secure Diamond standards, offering maximum protection against snapping, bumping, drilling and picking attempts.

Where to use a euro cylinder lock?

External Doors: Opt for double-cylinder or thumb-turn options for secure and convenient access.
Windows, Garages, Sheds: Choose half cylinders where one-sided key access is optimal.
Multi-Door Setup: Ask about keyed-alike options to use one key across multiple locks for streamlined convenience.

Not sure which type of euro cylinder lock you need?
