In the early 1980s, Master Locksmith Brian Preddey recognised the need for a lock system which provided resistance to picking, impressioning and key duplication. As a result, Brian developed a U-shaped key operating on up to twelve tumbler pins, which in turn activate two sidebars. Brian continues to play a vital role in Australian Lock Company's product design and development, with New Generation BiLock the latest addition to his stable of product initiatives. 

The Australian owned and operated Safecorp Group acquired Australian Lock Company in 1989. The Group continues to invest heavily in more sophisticated plant and equipment to augment production and design 
efficiencies of the world standard BiLock product range.


With all these products there remains a commitment to developing and introducing innovative lock security products designed to complement the BiLock range and quality for users.

In achieving this objective, a high priority is placed on Research and Design. This unique aspect to the Australian Lock Company incorporates the combination of specialist expertise, technologies and engineering to ensure optimal product diversity and integrity.

New markets and new applications bring new product requirements. Australian Lock Company continues to develop new BiLock products at a rate of 40 to 60 per annum and establish and open new markets both within Australia and overseas. Our ability to develop new cost effective, quality products for niche markets allows the Company to continue its progressive international sales and marketing programs.

Into the new millennium, Australian Lock Company has created yet another innovation known as New Generation BiLock. New Generation BiLock can offer the security conscious individual, firm or public body a fully integrated, high security lock system designed to meet high security needs, with unparalleled flexibility from the 300-plus cylinder types in the BiLock range!

Australian Lock Company has recorded an enviable annual average growth rate during the past two decades. Whilst its core product range remains BiLock, in recent years the Company has embarked upon a product diversification program with a number of new products now on offer.
