To determine the dimensions of your euro cylinder lock, measure from the center screw hole to the outer edges. This yields two measurements, which together represent the size of your door lock. The sum of these two measurements should match the overall length of the cylinder. For instance, a 40/40 configuration would total 80mm in length. The measurements for A and B should equal C if you measured your cylinder correctly.

A Euro Cylinder lock, also known as a pin tumbler lock, is a popular locking system used in lock cases. It features a cylindrical profile with up to eleven pins, providing security for both domestic and commercial properties. Euro Cylinder locks are designed with a standardised profile, allowing them to fit a wide range of doors and locking systems in the UK and Europe
There are three main types: Full Euro Cylinder Lock (double cylinder, operated from both sides), Half Euro Cylinder Lock (single cylinder, accessed with a key from one side), and Thumb Turn Cylinder Lock (key on one side, knob on the other for easy exit).
Replacing a door cylinder, often referred to as a Euro cylinder or lock barrel, is a relatively straightforward process. You can follow our detailed step by step guide which leads you through the process start to finish.
SDH provides a diverse range of keying options to cater to your specific needs. By default, individual door cylinders come with their unique key or key set. However, we also offer the convenience of keyed alike cylinder pairs, which are ready to ship at the time of purchase, allowing a single key to operate both locks. One common application for keyed alike pairs is for residential front and back doors, streamlining access for homeowners. Should you require additional matching cylinders, we offer keyed alike singles. You can achieve this by ordering multiple units of the same cylinder in a single purchase. Please note that mulitple keyed alike cylinders are made to order and will extend duration of the shipping process. Contact us for more details.
There are two main certifications when it comes to testing and certifying door cylinders. BS EN 1303 is a British classification system defining safety and security tests for locks. It assigns eight digits to a cylinder, indicating its effectiveness in various tests, ranging from corrosion resistance to torque resistance. TS007 is a security rating for locks tested against attacks like picking or bumping. It provides a star rating (1 or 3) to indicate the level of security against unwarranted access methods.
The number of pins in a Euro Cylinder lock determines its level of security. More pins generally provide increased complexity, making the lock more resistant to picking and other unauthorised access methods.
The British Standard TS007 uses a star rating kite mark system to indicate the level of security a cylinder provides. Kitemarked door cylinders can be awarded either 1 star or 3 stars. The stars represent different levels of security features and testing. : The level of security needed depends on your specific requirements and concerns. While a 3-star cylinder offers the highest security, a 1-star cylinder, when combined with a 2-star security product, can also provide robust protection.
Thumbturn Euro cylinders are measured similarly to standard door cylinders. The first measurement refers to the Thumbturn side, while the second measurement refers to the key side. For example, in a 35/45 cylinder, the 35mm is the distance from the Thumbturn to the fixing hole, and the 45mm is the distance from the key end to the fixing hole.
