What Our Customers Say

I have used Diamond Lock & Security for over two decades and continue to be delighted in their customer service, attention to detail and value. A recent experience with them was the development of a security /intercom solution for our new home. This was provided in a timely, affordable and professional manner. We will continue to use Diamond Lock & Security for our investment property portfolio and also happily recommend them to our clients, friends and family members.

- Iain & Ingrid, West Leederville

I’d like to thank your guys for the install of the locks as well, even though I could have changed them out myself as it’s an easy install they saved me a few days’ work.I have had previous experience with this system at Christmas Island and Karratha Airports and this is the reason I had them installed here at Learmonth and would recommend Cyberlock to anyone who still has an old keyed system.I’d also like to thank you at Diamond Lock & Security for your help on this project, being remote is not always easy but you guys made it so.

- Stephen, Airport Manager

An unfortunate event (having my keys stolen) gave me the opportunity to meet Andy Brown of Diamond Lock & Security, who came to my house this morning to replace several door locks.Andy completed his work with great professionalism. With patience and skillful competency, Andy took the time to fix a problematic front door which refused to work after a simple lock replacement.I will be a returning customer (touch wood).
