Keso® F1 High Security Cylinders

Providing the highest level of key-system security available on the market, the Keso® F1 Key System features 12 cylinder pins—twice as many as the standard six—making it impossible to determine the configuration of the key system or its upper level master keys by examining the pinning configuration. Additionally, precise manufacturing and the absence of splits leave the cylinder highly pick-resistant.


  • Secure: Building owner has full control over field duplication of keys
  • Flexible: Up to seven levels of master keying available, with 100,000 different key positions available within any one installation
  • Convenient: Key is symmetrical and reversible, and available in mortise, rim, key-in-knob and lever cylinders
