Mechanical locks remain a core part of commercial security. They provide predictable, consistent performance across offices, retail stores, hospitality venues, education facilities, warehousing, and industrial sites. With a wide range of commercial-grade hardware available, we can secure single doors, complex sites, and everything in between.
Businesses rely on locks that can survive heavy use and deliver consistent protection. Our locksmiths install commercial-grade deadbolts, mortice locks, mechanical keypad locks, and restricted key systems—built to secure staff-only areas, storage rooms, external entrances, plant rooms, and operational spaces.
We tailor each setup to your business requirements, ensuring your lock hardware aligns with insurance standards, compliance needs, and site accessibility.
Before installation, our licensed technicians will assess your doors, hardware, and home layout to ensure the right fit, both in terms of functionality and appearance.
We work closely with building managers, business owners, and facility teams to deliver long-lasting, reliable lock systems.
Whether you’re upgrading your building’s security, replacing worn hardware, or setting up a new premises, our team can help. We provide fast installation, expert recommendations, and high-quality commercial lock solutions built to last.
A master key system is a hierarchy of keys that allows you to control who can access specific areas of your building.
For example, a business owner can hold a "Master Key" that opens every door, while staff members hold keys that only open the front door or their specific office.
This reduces the number of keys you need to carry and significantly improves internal security and convenience.
The main reason businesses choose mechanical digital locks (push-button locks) is their independence from power sources.
Because they do not require batteries, wiring, or Wi-Fi, they are incredibly reliable and low-maintenance, making them perfect for staff rooms, storage cupboards, or rear entry gates where changing batteries would be a hassle.
Commercial locks are built to a much higher standard than residential hardware and are designed to withstand hundreds of thousands of opening cycles.
With proper installation and occasional maintenance, a high-quality commercial lock can last for decades.
If your lock is becoming difficult to turn, it may just need servicing or lubrication rather than a full replacement.
In many cases, yes. We can often retrofit high-security, restricted cylinders into your existing lock hardware.
This allows you to upgrade your security level and prevent unauthorised key duplication without the cost of removing and replacing the entire lock body or handle set.
High-traffic locks should be checked annually to ensure the door alignment hasn't shifted and the latch is engaging smoothly.
We also recommend lubricating the internal mechanism with a dry graphite or silicone lubricant (not oil) to prevent wear.
Regular servicing prevents "lock jams", which can otherwise result in expensive emergency callouts.
