    Getting locked out of your home doesn’t need to be a nightmare. We provide the help you need. With the number of home invasions, robberies and other offences it’s critical now more than ever to have your property secured but a trusted residential locksmith.

    Your home is one of your biggest investments, and it’s only right that you take care of it. Using quality restricted locking systems is the most efficient way to protect and control access your assets. And that’s where Diamond Lock & Security excels.

    You need a residential locksmith when:

    • You’re locked out of your house
    • You lost your keys or locked them inside
    • Your keys were stolen
    • You’ve moved into a new home and want new keys after replacing the locks
    • You broke your keys
    • Your locks are damaged


    The basic principle of running a business is to provide goods or services (or both) to customers. The goal is to maximise the investment of the business owner to grow and prosper. But that purpose is significantly hindered after a burglary. Theft and other crimes, including unauthorised access to the commercial property, should be taken seriously. And we’re here to help.

    An unhappy former employee, broken or damaged locks, lost keys, or faulty key card readers are just among the problems you need to be aware of. With your busy schedule, the last thing you want to face is a safety issue that could have been prevented with reliable commercial locksmith service.

    Diamond Lock & Security can provide the locksmithing service you need for your company. Just like you, we are a business, and we know how important it is to keep everything secure. From inventory to printed documents to soft records, all these essentials require high-quality solutions to ensure their safety.

    Car lockouts, broken key locks, key replacements – you name it, we can do it! Our pros are certified with adequate training and knowledge. It’s why we are confident that we can work with a smart key and remote key (whether it is a genuine or aftermarket item).

    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).
