Measure from the face of the cylinder on the outside of the door to the center of the cylinder's screw hole. Then, measure from the center of the screw hole to the face of the cylinder on the inside of the door. The size is represented as External/Internal (e.g., 35/45).

The Kinetica+ K4 is a Euro profile cylinder and is compatible with most standard uPVC, composite, and some timber doors that accept this type of cylinder. The critical factor is ensuring you order the correct size.

The Kinetica+ K4 is designed with a sacrificial cut. It will snap on the outside, but the internal mechanism is protected by an anti-grip drive bar and dual attack rods, preventing the lock from being opened from the inside or manipulated. The lock remains operational from the inside.

The 'Brass' colour family refers to the finish of the cylinder, which is typically a brass-plated or coated material to provide a specific aesthetic. It is not usually solid brass.

The TS2007 3-Star is a British Standard rating for lock cylinders, indicating it meets the highest security requirements for resistance against burglary attacks such as drilling, picking, and bumping. It is often a requirement for insurance purposes.

Double-check your measurements against the cylinder size you ordered. Ensure the lock case and door preparation are standard for a Euro profile cylinder. Forcing the cylinder can cause damage.

Ensure the cylinder is correctly aligned and fully seated in the lock case. Check that the retaining screw is not overtightened and is pinching the cylinder. Try a small amount of graphite lubricant in the keyway. Ensure the correct key is being used.

This could indicate an incorrect size cylinder or a problem with the internal lock mechanism. Verify measurements and consider if the issue persists after correct installation. It may require professional assessment of the door's multipoint lock.

The retaining screw may be too tight, slightly deforming the cylinder. Loosen the screw slightly and re-test. Ensure no debris has entered the keyway during installation.
