2. Keyed Alike A group of padlocks/cylinders are all operated by one key. This key profile can be allocated a code and future key and padlock/cylinder orders can be placed against this code.

3. Master Key Installations A group of cylinders or padlocks are each equipped with an individual key and are also operated by one special key known as a Master Key (MK).

4. Grand Master Key Installations A Grand Master Key is used when it is necessary to have more than one Master Key group in the same building complex. In these instances all cylinders, irrespective of their Master Key group, are controlled by one key known as the Grand Master Key (GMK).

5. Construction Master Key (CISA only) The Construction Master Key is designed to enable the contractors to operate all cylinders belonging to the system with a temporary Master Key known as a Construction Master Key. This maintains the integrity and security of the original keys delivered directly to the owners as the Construction Master Key will be deactivated when the owner’s keys are used.

6. Lockout Master Key System (CISA only) When a master key is lost or stolen, the Lockout Master Key enables the owner to operate all cylinders belonging to a system with the lockout master Key thereby locking out the original master key. Tenants are not affected. The security of the enterprise is not compromised and expensive re-keying of all cylinders is avoided.
