Euro Cylinder Locks for Every Door Type

Euro cylinder locks — also known as lock barrels or door barrels — are the most common lock type fitted to uPVC, composite and wooden doors across the UK. Whether you need a replacement euro cylinder for your front door or you are upgrading to a high security anti-snap cylinder, our range covers every door type and security level.

We stock standard euro profile cylinder locks, TS007 3-Star anti-snap cylinders, thumb turn options and keyed alike sets from trusted brands including Avocet ABS and Yale. Every cylinder is available in multiple sizes and finishes, with fast UK delivery on all orders.

Anti-Snap Euro Cylinders

If your door has a standard euro cylinder without anti-snap protection, it may be vulnerable to lock snapping — one of the most common burglary techniques in the UK. Anti-snap euro cylinders are designed with a sacrificial cut line that breaks away under attack while keeping the main locking mechanism secure.

Our anti-snap cylinders are independently tested to TS007 3-Star and Sold Secure Diamond standards, providing maximum resistance against snapping, bumping, drilling and picking. The Avocet ABS range features patented Snap Secure technology with an active cam that locks the cylinder after an attack, creating a total barrier to entry. The Yale Platinum range offers 3-Star kitemarked protection with anti-bump, anti-pick and anti-drill features as standard.

How to Measure a Euro Cylinder

Getting the right size euro cylinder is essential for a proper fit. To measure your existing lock barrel:

1. Remove the cylinder from your door by undoing the single fixing screw on the edge of the door.
2. Measure from the centre of the screw hole to one end — this is your internal measurement (A).
3. Measure from the centre of the screw hole to the other end — this is your external measurement (B).
4. Your cylinder size is expressed as A/B, for example 40/50 (90mm overall).
