Replace or upgrade the cylinder in a uPVC, composite, aluminium, timber, garage or entrance door. Choose from euro-profile, thumbturn, half-euro and rim cylinders, including standard-security locks, anti-snap options, keyed-alike sets and replacement-key services.
Measure the cylinder from the centre fixing-screw position to each end before ordering. The two sides can be different lengths, so record the internal and external measurements separately.
Most modern uPVC and composite doors use a euro-profile cylinder, but the correct configuration depends on the door and how it is operated.
Euro-profile cylinders Thumbturn cylinders Half-euro cylinders Rim cylinders Key-cutting services
Measure from the centre of the fixing screw to the outside end of the cylinder, then repeat from the centre to the inside end. Write the size as two measurements, such as internal/external. Check which side contains a thumbturn where applicable.
A cylinder that projects too far beyond the door furniture can be more exposed to attack, while one that is too short may not operate correctly. Compare the new size with the fitted cylinder and the thickness of the door handles or security escutcheons.
The range includes standard-security cylinders and higher-security products with TS007 star ratings. Options include anti-snap, anti-pick and anti-drill features, depending on the individual model. Check the product specification for the exact certification and protection provided.
Keyed-alike cylinders allow more than one lock to operate with the same key. Thumbturn cylinders provide key operation outside and a turn knob inside. Half cylinders are commonly used where access is required from only one side, including some garage-door applications.
Our range includes Yale Platinum and Superior, Avocet ABS, GreenteQ Orion, Fullex Kinetica+, ERA Fortress, Mila BreakSafe, UAP, Versa, Eurospec and JCP cylinders. Available security ratings, sizes, key quantities and configurations vary by product.
You can estimate the dimensions while fitted, but removing the cylinder normally provides the clearest and most accurate measurement from the centre fixing-screw position.
No. Many doors require an offset cylinder with different internal and external measurements.
Keyed-alike cylinders are prepared so the same key operates multiple locks. Check whether the product is supplied as a set or made to an existing compatible key code.
No. Security features and independent ratings are separate product specifications. Check the individual listing for its confirmed star rating and certification.
