The Master Locksmiths Access Key (MLAK) system is an initiative that allows people with 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. People with a disability are able to purchase an MLAK key that will open all doors, toilets, playground equipment and other facilities fitted with a lock that uses the special MLAK cylinder.’

There is an online order form and the cost of the key is $25 plus postage.
