CISA C2000 Open Keyway Large Oval Profile Cylinders
How the Open Keyway worksAn 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.
- 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.
- Number of key differs: over 30,000.
- Push resistance: projecting cam.
- Drill resistance:
- Hardened steel pin and driver in first position
- Anti-picking resistance:
- Para-centric key way
- Mushroom type drivers.
