How
to replace a Euro Cylinder
Euro cylinders in UPVC doors are secured by a screw on the locking
face of the door. This screw is located level with the bottom of cylinder.
Unscrewing this will release the Euro Cylinder and it will slide out.
It is important then to measure the cylinder to ensure the right size
replacement is purchased. Measure the cylinder you have removed from
the one face (where the key goes in) to the fixing hole under the cam
(the rotating arm of the cylinder) and then measure from the fixing
hole to the other face of the cylinder. These 2 dimensions give you
the size of your cylinder for example the cylinder in the diagram would
be a A/B (A and B being the respective measurements in mm). Slide the
replacement cylinder in ensuring that if your cylinder is uneven the
longer side is on the correct side. The fixing screw will not go back
in if the cylinder is wrong. Secure the screw and your lock is changed.
