Darwin Restricted Keys

Losing control over who can copy a key to your home or business can be a serious security risk – especially in shared spaces, commercial sites or government settings. That’s why Darwin Lock & Key offers a full range of restricted key systems in Darwin, designed to give you complete control over who can access your premises and when. These systems are perfect for anyone who wants true peace of mind and legal protection against unauthorised duplication.


  • Key copies require authorisation and ID
  • Suitable for homes, businesses and secure sites


We offer a range of restricted key systems, which can give your home or business a high level of security. Restricted key systems provide you with peace of mind regarding the security of your premises.


Restricted key systems offer key control, which means no one else can have a key unless authorised. Even copies are restricted, and only authorised locksmiths supplied with appropriate forms and photo identification can make copies of restricted keys.


Darwin Lock and Key offer three restricted systems: BiLock Restricted Master Key Systems, Abloy Protec, and Abloy Protec Cliq. Call (08) 8948 1966 today to speak with our team and find the best solution for your security needs.

BiLock, Abloy Protec & Abloy Protec Cliq

We supply and install three types of restricted key systems, each offering a different level of control, compliance and convenience. Our available options include:


BiLock Restricted Master Key Systems

BiLock Restricted key systems are a state of the art u-shaped key protected by restricted dealers and legal security. BiLock is a mechanical restricted key system with colour-coded heads with 8000 different combinations. BiLock is pick, bump and impression resistant.


BiLock keys are SCEC (Security Construction and Equipment Committee) approved for secure area applications and can be used in conjunction with Salto Access Control Systems, in which case a micro-encrypted RFID chip is built into the head.


BiLock Restricted keys are used in homes, commercial offices, by government departments, by the Department of Defence and the Australian Defence Force. BiLock are at the forefront of restricted keying systems and offer a highly restricted keying system, providing you with the control to protect your home or business and family at an affordable price.


Abloy Protec

Abloy Protec provides a long lasting physical and legal protection against unauthorised key reproduction. Abloy Protec is a full metal, colour-coded key, and it is recognised for its physical security as well as its durability. Abloy Protec is recognised as the premium high security mechanical locking system in the security industry, and it is used extensively by private, commercial, government departments, Department of Defence as well as the Australian Defence Force – all of whom demand the ultimate in high security master key systems.


Abloy Protec is SCEC endorsed for secure area applications. The strong one-piece metal key minimises the chance of breakages through wear and tear and prevents ongoing key replacements. The absence of pins and springs used in the cylinder provides unmatched resistance to wear and tear and corrosion of internal parts.


Abloy Protec is distributed through a highly restricted dealer network of locksmiths who represent the highest level of professionalism and ethics in the industry.


Abloy Protec Cliq

Abloy Protec Cliq is a new keying platform for Australia. Abloy Protec Cliq is a combination of the already successful and proven SCEC approved Abloy Protec and the newly developed Cliq technology, that was developed in Sweden by Assa Abloy's research and development engineers.


With no wiring required this new keying system can replace existing mechanical key systems – offering the functionality of access control systems and a restricted key system at just a fraction of the price of conventional hard-wired systems.


Abloy Protec Cliq's intelligent cylinder system presents a hybrid electromechanical locking system, which combines the reliability of superior mechanical keys and cylinders with the programming sophistication and flexibility of Cliq technology.
