janus – more security

The reversible key system janus meets the highest standards of security, functionality and design. As a premium solution, ideally suited for locking systems. Security is one of the most important criteria for the janus locking cylinders from BKS. The security card ensures that only the cardholder can order keys or have them duplicated. This makes the janus one of the safest mechanical locking systems of all.



  • More comfort even with tall or heavy doors: the generous janus grip area of the key means straightforward opening and closing via the cylinder
  • Striking design: the red ball is a sign of BKS quality and accentuates the symmetry of the reversible key
  • Impressive in operation: the extended key shoulder makes janus well suited for security hardware with a cylinder cover
  • Greater security: first-class drilling/picking and key duplication protection
  • Straightforward handling: the symmetrical design and familiar upright key position ensure intuitive operation
  • Protection against picking as standard
  • Emergency function that prevents blocking by inserted keys
