pextra+ Security lock cylinder with extra protection

pextra+ meets EN1303 Key Related Security Grade 6 and is a Kitemark Approved, TS007 1-star cylinder* that protects against drilling, picking and bumping.

The sophisticated, patented key profile, with our unique “branch groove” means duplicate keys cannot be made using commercial key milling machines. The optional blocking pin verifies the presence of the branch groove for added security. If the original branch groove is not detected, the blocking pin prevents the key from being turned completely in both directions.

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.

*Kitemark only applies to euro profile cylinders only.
