Looking for an expert when it comes to master key system installation? If you’re a landlord, business owner or manage multiple sets of keys for offices or retail units, you’ll be well aware how quickly ‘one more set’ becomes one set to many.
A master key system takes that chaos away. You’ll have one secure key that opens the doors you need, and your tenants or staff will only access the areas they’re meant to.
We’ve set up key management systems for landlords, property managers, and commercial buildings across Chelsea, South Kensington, Kensington, and Earls Court, helping make key control simpler and security tighter.
Whether you manage a few units or multiple properties, we’ll design a setup that gives you fewer keys, clear access levels, and complete peace of mind.

Being responsible for a building is stressful at the best of times. Throw in key management with multiple tenants losing or breaking keys, and you end up replacing locks and handing out copies again. Oh, and the costs add up quickly!
A well-planned master key system stops that cycle. You’ll have total key control and a clear structure of who can access what.
Here’s what a proper setup offers:
Convenience: You’ll carry one master key instead of a bundle of ten
Security: With restricted key systems, no one can cut duplicates without authorisation
Efficiency: If you manage multiple sites, we can integrate everything into one key management system
Flexibility: We’ll tailor your access control to match your layout and business needs
It’s a small change that makes a huge difference to your daily operations.
You’ll have one master key that opens all locks within your building or site. Beneath that, we create sub-master keys that open specific areas, such as individual offices, staff rooms, or storage spaces.
Each tenant or employee gets an individual key that works only for their assigned area. You’ll still be able to access every lock if needed, perfect for emergencies or maintenance visits.
For larger properties, we can even install a grand master key that operates across multiple buildings, ideal for landlords or facilities teams managing entire portfolios.
This is how professional key management should work: clean, simple, and secure.
Lost keys are a real headache, especially in shared buildings. That’s why most of our installations use restricted key systems.
These systems use restricted key blanks that can only be cut by authorised locksmiths. No high-street kiosk can copy them, so you’re always in control.
When you need extras, we’ll supply them only to authorised personnel with proper identification.
If you’re a landlord or property owner, a landlord master key setup will save you time, money, and stress. You’ll still have access to all your tenants’ doors (with notice, of course), but each tenant will have their own unique key.
We often install these for:
Multi-unit apartment buildings
Student housing
Office complexes
Retail units
It’s all about controlling access while keeping tenant satisfaction high.
Each of these systems sounds similar right, and you could be forgiven for thinking that they’re the same.
While they sound similar, but each system works a little differently, and what’s right for you really depends on how your building’s used.
A keyed alike setup keeps things simple. Every lock opens with the same key. It’s neat and tidy for small offices or single-unit properties where everyone needs the same level of access. You’ll only have one key to think about, but that also means anyone with it can open everything.
A master key system gives the property manager more control, that’s you. While each door will have its own key, your master key will open them all. The perfect solution for anyone not wanting to carry around a pocket full of keys, but who does need to access different doors.
Then there’s the grand master key setup, which is your top tier. It controls several master key groups at once, so you might have individual keys for tenants, master keys for maintenance, and a grand master key for full access.
Modern key systems don’t just stop at traditional locks. We can integrate electronic access control options such as fobs, key cards, or coded pads, ideal if you want audit trails or digital logs of who’s entering where.
We work with:
Mechanical key systems for reliability
Electronic systems for advanced access control
Multi-layered key management systems that grow with your building
You’ll always have a solution that fits your property’s security needs, whether that’s a small office or a full commercial building.
The total master key system cost will vary, depending on factors such as:
Property size
The number of locks
The amount of access control you need
For a single building, setup typically starts from a few hundred pounds, while multi-building or restricted key systems can be more, depending on the complexity.
The important thing is you’ll save long-term, fewer lost keys, no emergency call-outs, and less downtime. It’s one of those upgrades that pays for itself over time.
If you’d like an exact quote, give us a call, we’ll measure, design, and price your entire system upfront.
And you can rest assured that we won’t over charge you for your master key systems, we pride ourselves on our honest and transparent pricing.
You will obviously need to maintain your master key systems once they’re installed. But that is something that we can help you with. We’ll help store master keys securely, update your records and ensure that no duplication of master keys takes place.
You’ll get a detailed record of all key holders, and we’ll assist with replacements if one goes lost or stolen. Regular key control checks mean your property always stays secure, even years down the line.
If you’re managing commercial buildings, apartment blocks, or multi-unit properties, a master key setup just makes sense. You’ll have one clear key management process and full visibility across all access points.
From laundry rooms to maintenance cupboards and tenant doors, we’ll make sure everything locks and opens exactly as intended, no confusion, no wasted time.
If you manage or own commercial buildings, you already know how tricky key systems can get once there are multiple doors, tenants, or departments involved. A proper master key system saves you the headache, you’ll keep control over who can access what, without juggling multiple keys.
Every master key system is tailored to your layout and business needs. You can limit access to specific areas, give maintenance staff partial entry, and still have one master key that opens everything when you need it.
And if you’re working with a restricted key system, you’ll also get peace of mind knowing your keys can’t be copied without approval. Only our authorised locksmiths can duplicate or replace them, helping you protect your tenants, staff, and stock at all times.
One of the biggest advantages of a restricted key system is controlled duplication. That means nobody can walk into a shop and get your key copied, it’s protected under a registered design. Only authorised locksmiths (like us) can legally cut new keys, and only with written permission from you, the key holder.
This level of key control is essential for any master key system used in commercial or multi-unit buildings. It keeps track of every copy, protects your security setup from human error, and makes managing multiple keys far less stressful.
A restricted key system also reduces the risk that comes with lost or stolen master keys, because you’ll always know exactly how many keys exist and who has them. That’s what a professional key management system should give you, confidence that your building’s access is in safe hands.
Every business has areas that not everyone should enter, storerooms, plant rooms, server cabinets, staff-only zones. A master key system gives you the control to set clear access levels so you can decide who gets in where.
You might have cleaning staff who only need certain floors, or tenants who should only access their own units. With a properly planned key system, you can make that happen easily.
Whether you’re managing one building or a portfolio of properties, we’ll help you simplify your key systems while keeping the level of security exactly where it should be.
Sometimes, traditional key systems aren’t enough — especially if you need to log entries or update permissions quickly. That’s where electronic access control comes in.
We can combine a master key system with electronic access control to create a flexible setup that works for modern offices or multi-unit buildings. You’ll have the option to use key cards, fobs, or digital credentials alongside your restricted keys, giving you the best of both worlds, physical security plus real-time access data.
When your business grows, so does your keychain. A clear, well-documented key management system helps you stay on top of it all, who has which key, what it opens, and what happens if one goes missing.
We also make sure your master key systems comply with local building and fire safety standards. You’ll have records for your own peace of mind and easy updates if anything changes, whether it’s a new tenant moving in or a staff reshuffle.
The master key system offers convenience, key control, and the ability to react quickly when something goes wrong. Avoid changing locks in the future. A few hundred pounds spent on proper planning now can save a lot more later.
