High-Security Lock Cylinders

The average Euro profile cylinder can be snapped in seconds by burglars using simple household tools, and over 20 million uPVC and patio doors in the UK are at risk. These ranges of high security cylinders are designed to withstand attack. They are easy to fit in about 5 minutes – see our measuring and fitting guide and fitting videos.
