Master Key System Design
A dental office wants the front desk to lock up at night without ever holding a key to the room where patient records and controlled supplies are stored. Right now one master key opens both, which nobody is comfortable with once it is pointed out.

In a building shared by several tenants, departments or contractors, master key system design draws a clear line between who needs a broad master and who needs a single change key for their own door. Cleaners, maintenance staff, department heads and the owner typically sit at different levels, and the hierarchy is built to reflect that rather than to make life easier for whoever is issuing keys that week. The chart that results shows every level at a glance, which makes it far simpler to answer a basic question: who can currently get into this room.
How the visit goesA self-storage operator wants the office, the tenant gate and the equipment shed on three different levels of access for staff, but every lock on the property currently answers to the same handful of interchangeable keys handed out over the years.

How the visit goes
- 1
Where a sub-master genuinely earns its place
Not every group of doors needs its own level. The assessment looks for places where a sub-master is a real convenience, such as a department, a floor, or a set of storage rooms used by the same small team, rather than adding levels for their own sake. A hierarchy with more levels than the business actually uses is harder to manage and easier to get wrong later, so this stage is as much about deciding what not to build as it is about what to include, before any pins are cut or any key blanks are ordered.

Handling a lost key discovered mid-project
If a key turns up missing or unaccounted for while the assessment is underway, the affected level is dealt with before the rest of the design continues: the doors that key can reach are identified from existing records or, where none exist, from a physical walk of the property, and those cylinders are prioritized for repinning ahead of the rest of the schedule. Folding this into the same visit avoids a second project later to close a gap that was already known about.

Knowing exactly what a lost key affects
If a key goes missing later, the chart tells the business precisely which doors that level can reach, rather than leaving anyone guessing whether the whole property needs attention. That scope can then be compared against how the key was likely lost and who else already holds that same level, so the response, whether rekeying one group, one door, or leaving it recorded and monitored, is a decision made with real information.

What affects the quote
- 1
Collecting and retiring old keys
Gathering up old keys that are being replaced, confirming they no longer operate any cylinder, and retiring them from circulation is a small additional step some businesses want included, separate from the core design and cutting work.
- 2
Working around an occupied, operating property
Rekeying doors in a planned sequence so a business keeps operating throughout, rather than all at once, takes coordination with the owner's schedule. Properties that need this staged approach, with interim arrangements for doors mid-conversion, add planning time beyond a straightforward, all-at-once installation.
- 3
Number of keys cut and marked
Each key cut and marked for a holder is counted individually in the quote, whether it is a change key for one door or a top-level master for an owner. More staff at the same level naturally means more keys cut than a business with only a handful of holders.

Master Key System Design: questions
Can key duplication be restricted so copies cannot be cut elsewhere?
Yes. With a restricted or patented keyway, blanks are only available through the manufacturer's authorized record, so a copy is not cut at an ordinary hardware counter without going through that channel. This does not make a key impossible to duplicate, but every legitimate copy passes through a record the owner controls, which a standard keyway cannot offer.
Should I keep spare blanks or unpinned cylinders on hand?
It depends on how the keyway is controlled. With a restricted system, spare blanks are typically held by the locksmith against the authorized record rather than stored loosely on site, since that is what keeps duplication contained. With a standard keyway, keeping a few spare cylinders of the same platform can simplify a later addition, though it is not required.
How long does designing and installing a master key system take?
It depends on the number of doors and levels involved. A small business with a handful of doors and one or two levels moves through assessment, pinning and testing in less time on site than a multi-floor property with several departments and a top-level master, where more doors, more testing and more keys to cut all add to the work involved.

What the census means at the door
42%
Homes of every age. About 42% of homes in Uxbridge were built in 1980 or earlier, according to the 2021 Census.
In an area where homes span several eras, one street may have original mortise locks and the next builder-grade cylinders. A locksmith working here carries parts for both, so whichever door he meets, the job finishes in one visit.
81%
Mostly houses. Single-detached houses make up about 81% of homes in Uxbridge (2021 Census).
In areas of single houses, the door nobody watches is the side or back entry. It often has the weakest lock on the property. Fitting a proper deadbolt and a reinforced strike there is a modest job that closes the obvious gap.
