CISA C2000 Open Keyway Cylinders

CISA C2000 Open Keyway Steel Padlock Cylinder

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.


  • The Hardened Steel Padlock needs to be upgraded to keyed alike or master keyed to a Master Key system
  • When the key security needs to be upgraded from an Open Keyway to either a Restricted Keyway (G Keyway) or Protected Keyway such as Ap3, Astral Tekno or C3000
