CISA C2000 Open Keyway Cylinders

CISA C2000 Open Keyway Rim Cylinders

How the Open Keyway works

An open keyway does not offer protection against un-authorised copying of the key as the key blanks are easily available. For complete protection from un-authorised duplication of your keys look at Astral Tekno, AP3 and C3000 keyways.


As a replacement cylinder for night latch locks

  • Where more security is required than a lever lock where the exact key for your lock is available from a local hardware store. The CISA key can only be duplicated by taking the original to a locksmith.
  • Where keyed access is required from only one side of the door.
  • For convenience, no key is required to operate the cylinder for locking/unlocking the door from inside, simply turn the knob on the night latch rim lock.
