The Industry Standard in Long-Term Security: Master Locksmiths ML20

When it comes to future-proofing your security, the Master Locksmiths ML20 system stands in a league of its own. Developed by the Master Locksmiths Association of Australia (MLAA), the ML20 is a high-security restricted keying platform designed to provide maximum protection and strict key control for decades to come.

The standout feature of the ML20 is its incredible longevity—with design patents extending until 2040, you can rest assured that your system remains legally protected against unauthorized key duplication for the long haul. This makes it an ideal investment for schools, hospitals, government facilities, and large-scale commercial developments that require a stable, permanent security solution.

At Aus Lock and Safe Co., we leverage the ML20’s versatile range of profiles (including A, B, C, and M profiles) to create highly complex master key hierarchies. Whether you need to manage a handful of doors or an entire multi-site corporate network, the ML20 delivers the physical robustness and administrative control required to keep your premises secure.

"One of the hardest inline restricted systems to manipulate”

Designed by Master Locksmiths, the best in the industry, you get superior key profile design, which ensures the key clamps & cuts correctly and is one of the hardest inline restricted systems to manipulate. Keys and Barrels are manufactured together to ensure the highest tolerances

Key Profiles A,B,C & M. M is a Master profile. M Keys will work in Barrels that accept either keys A,B,C or M

Keys are made of "Nickel Silver" to provide optimum strength

Barrels come in profiles A,B,C & M+. "M+" Barrels are unique and will accept ALL A,B,C & M Keys
