There are online articles showing ways to breach master key security systems. Unfortunately, the first to suffer was the humble “inline pin cylinder” which is the basis of approximately 98% of all locks in Australia.
The solution to beat the hackers is to install a state-of-the-art, high-security, master locking system, such as BiLock and ABLOY PROTEC.
These systems work in the same way as the restricted master key system and are used extensively by private, commercial and government clients. They are distributed only through a highly restricted dealer network.
ABLOY PROTEC: Featuring a long-lasting legal and physical protection against unauthorised key duplication, this product is the culmination of 90 years of world-leading development of the rotating disc cylinder. SCEC endorsed for secure area applications, this strong, one-piece metal key ensures against expensive ongoing key replacements. The absence of pins and springs provides unmatched resistance to wear and corrosion of internal parts.
BiLock: This is the most recognised high-security master key system commonly used by the Royal Australian Mint, Las Vegas casinos, international airports and military establishments.
The entire lock is self-contained within the one-half inch plug diameter. It includes two parallel rows of 6-pin tumblers with each row acting independently with its sidebar—the equivalent of two sidebar locks in a one-half inch cylinder.
Each side of the lock is operated separately by each half of the dual-bladed key. Both the lock mechanism and the key forming process are patented worldwide.
