A Young man by the name of Clayton just left after fixing the lock on my front door.  He represented your company proudly. He was well dressed, well spoken. He kept me informed of his progress on my job at all times and rang well in advance to let me know when he would arrive.  I would recommend your company to my friends because of how Clayton represented your company.


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).



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 and Security for your help on this project, being remote is not always easy but you guys made it so.


Stephen, Airport Manager

I have used Diamond Lock and 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 DLS for our investment property portfolio and also happily recommend DLS to our clients, friends and family members.
