The Master Locksmiths Access Key (MLAK) system is an MLAA initiative that allows people with a disability access to dedicated public facilities, including facilities in National Parks and many Council municipalities, elevators at railway stations, the new Changing Places facilities throughout Australia, disabled toilets that are locked, and even the Liberty Swing. It was launched back in 1994 as a joint venture between Pittwater Council, ACROD and the MLAA, before being implemented Nationally.

People with a disability can purchase an MLAK key which will open all toilets, playground equipment and other facilities fitted with a lock that uses the special MLAK cylinder.
