CISA C2000 Open Keyway Cylinders

CISA C2000 Open Keyway Electric Lock Cylinder Sets

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.

CISA electric lock cylinder sets are very useful when:

  • The cylinder on the electric lock needs to be extended
  • The electric lock needs to be 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 or Protected Keyway such as Ap3, Astral Tekno or C3000
