Commercial Locksmith


We provide services to commercial businesses and organisations, including hotels, restaurants, retail and shopping centres. We also have customers in the education industry like public and private schools and universities, as well as government offices.

Our locksmith services are highly sought after in the seniors housing industry, where retirement villages require bolstered locking systems. The same goes for apartment complexes.

At Diamond Lock & Security, we are firm believers in safety as your most significant investment. That’s why it makes sense that no matter what your industry may be, you should always prioritise the security of your facility, assets, and the business itself.

A commercial locksmith provides efficient locksmithing and security installations to commercial and industrial properties and clients. Commercial locksmiths can also perform periodic maintenance, repairs, and replacements when required.

Unlike a residential locksmith, there are much stricter commercial and industrial security standards. That’s why if you run a business, it is necessary that you hire the right type of locksmith to benefit from the needed expertise in your sector.

Commercial locksmiths regularly study and research new lock technologies. They can install new locks, provide rekeying services, and create spare keys for businesses. They also install security systems, including alarms, CCTVs, and access control systems. If this sounds like what you need, don’t hesitate to get in touch with Diamond Lock & Security to hire a commercial locksmith.

Like with residential properties, offices can lock out employees. It’s a common issue where someone loses or damages their key and cannot enter the premises. Old or malfunctioning locks are also a widespread problem in commercial facilities. We often suggest installing new locks, but we can repair damaged locks, as well.

Many commercial properties also have an issue with poor and outdated security. That’s where our locksmiths come in. Armed with up-to-date information, we can give you recommendations and install the best security system for your premises.

Other common problems that we take care of for our commercial clients include broken or loose locks, failing door closers, and safe installations.

Commercial spaces generally require special and more complex locks and security systems compared to private residences. We offer different services based on the requirements of the commercial property.

One thing that we often recommend is the master key system, which is designed by our very own locksmiths. This system uses only one key to access various areas, providing the master key holder with control. That means you do not have to carry a bunch of keys to unlock the doors. Retail and other huge spaces will surely benefit from our master keying service.
