CISA C2000 Open Keyway Cylinders

CISA C2000 Open Keyway Small Oval Profile 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.


Small oval cylinders are typically used on narrow style steel gates, expandable gates and narrow aluminium patio doors

  • All Cylinders: 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.
  • Double Cylinder: Where keyed entry access is required from both sides of the door.
  • Off-Centred Cylinder: Where a door has a lip at the closing end and the lock has to be morticed off-centre to accommodate the lip.
  • Half/Single Cylinders: Where keyed access is required from only one side of the door.
  • Thumb turn/Knob Cylinders: For convenience, no key is required to operate the cylinder for locking/unlocking the door from inside, simply turn the knob.
