Michael started his locksmith career at the beginning of 1998 as an apprentice and worked for 13 years for the same locksmith’s in the eastern suburbs. He started MJM Locksmiths in 2011 and has been running the business from that time onwards, making the most of all his knowledge and experience. Improving the security of his customers and their families has been his passion since he started. He is always striving to help his customers and answer the questions they may have about making their homes and offices more comfortable with the right locks and security systems.


Isaac started working in the building and trade industry at the age of 15. He has always had a passion for fixing and renovating houses, pulling apart mechanisms to see how they work and putting them back together. He prides himself on helping people in any way he can to fix building issues. He was asked by Michael to join MJM Locksmiths in 2012 and took up this new challenge. He brings to the business his many years of experience as a tradesperson and the pride that he takes in his work. He is eager to help more customers feel secure in their homes and understand their needs.
