SPECIAL KEYING
At our Melbourne facility the locksmithing department can cater to any specific keying requirement. A variety of systems are available, these include:
---
KEYED ALIKE
A keyed alike system is one where 2 or more locks are to be operated by the same key.

---

MASTER KEY SYSTEM
A master key system is one in which, each lock has its own individual key, which operates that lock only and no other. Within the system each lock is built to a master key which will open all locks in the group. Within the master key system locks can be grouped and keyed alike if required. These locks would still be operated by the master key.

Suitable for aged care, rooming houses, etc.

---

GRAND MASTER KEY SYSTEM
Each lock has an individual key, which operates that lock only, and no other, but the locks are divided into 2 or more groups. Each group is operated by a master key, which operates all locks in that group, but will not operate other groups. However, the grand master key will operate all locks in all groups. Within each group, locks can be keyed alike if required. These locks would still be operated by the grand master key system.

Suitable for schools, factories, office buildings, etc.

GREAT GRAND MASTER KEY SYSTEM
This system applies where 2 or more grand master key systems are required, with each grand master key system able to be operated by the great grand master key.

---

MAISON KEY SYSTEM
A maison key system is one in which 2 or more individual keys that differ from each other operate a common lock, eg foyer access, shared garage, common pool area etc.

If required this system can be included in a master key system.

---

PROJECT KEY SYSTEM
A project key system is one in which one or more locks are operated by a common key (project key) and an individual owner key supplied to each lock. The owner key is not used during construction (Fig.1). The use of the owner key cancels out the project key and renders it inoperative in that particular lock on any future occasion (Fig. 2).

---

PROJECT MASTER KEY SYSTEM
A project master key system is one that incorporates the benefi ts of both project and master key systems. The master or individual key is not used during construction (Fig 3). When the master or individual key is fi rst used, the project keys are rendered inoperative (Fig.4). The locks will then operate as a standard master key system.
