There are multiple ways in which a prospective burgular can attack a cylinder lock to try and gain access to your home. We know all of them, and the cylinders we use have defences against every method.

Our cylinders are...

• Anti Pick
• Anti Drill*
• Anti Bump
• Anti Snap**

* The cylinders are tested to EN1303:2005 with no less than 4 Anti Drill pins per side of the lock
** We use a Winkhaus cylinder guard to prevent cylinder snapping. See our options page for a picture.
