Product Summary

pextra+ Guard is dormakaba’s premium ‘break secure’, patented protected, high security mechanical key system. 

Part of the pextra+ cylinder family, pextra+ Guard has been specifically developed to meet the stringent requirements of the TS007 3-Star standard for lock cylinders.  Carrying the coveted BSI Kite Mark and endorsed by Secured by Design, the official police security initiative, pextra+ Guard boasts a sophisticated patent-protected key profile, preventing unauthorised key duplication, and physical protection against all common forms of cylinder manipulation including anti-drill, anti-pick, anti-bump and, crucially, cylinder snapping.

Cylinder snapping is a common method used to break into a property and requires zero skill by the thief. Many cylinders are marketed as being ‘anti snap’ or ‘snap resistant, which is an inaccurate term.  Pextra+ Guard features a sacrificial break slot, which ensures that the cylinder snaps in a designated place.  If the cylinder is snapped, the secure core of the lock is activated, preventing forced override of the cylinder, keeping your property secure. 

As part of dormakaba’s continual focus on product development, pextra+ now features our latest advancement “EKE” (Easy Key Entry).  EKE has been specifically developed to enhance the performance of our most complex serrated key system whilst still offering the highest levels of security and conformity to the same industry standards and certifications.  The precision milled EKE ramp effortlessly guides the key into the cylinder, ensuring a smooth and precise placement for authorised access.
