Master Key System Design in Armitage
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.

Master key system design is the work of turning a property's separate locks into one coherent hierarchy: a change key for an individual door, a sub-master over a department or floor, and one top-level master reserved for the few people who need it. The locksmith records who should open what, matches that list to the cylinders already installed or to new ones chosen for the job, and pins every lock so each key opens exactly its intended group. The finished system comes with a chart the owner controls, so access follows the organization instead of following whoever happened to be handed a spare key.
How the visit goesA property manager taking over a small commercial building inherits a shoebox of keys with no labels and no chart. Some open the mechanical room, some open vacant units, and a few do not seem to match anything currently on the property at all.

How the visit goes

- 1
Who holds the top-level master
A single top-level master, if the property has one at all, is deliberately kept to the shortest list the business can operate with. The check here is a direct conversation about who genuinely needs to open every door on the property versus who only thinks they might one day, since every extra holder is another way a full-access key can go missing. This conversation happens before cutting begins, because narrowing the list afterward means recovering and replacing keys that have already been issued to people no longer on it.
- 2
Choosing a platform with room in it
The keying platform and keyway are chosen to hold every level the design calls for, plus a margin for doors that are likely to join later. Each cylinder is then pinned chamber by chamber to the planned bittings, with bottom and master pins stacked together to create the shear lines every level needs to turn that one cylinder. Getting this stacking right is what prevents a common mistake: a change key that, through an overlooked shared pin, quietly opens more than the door or keyed-alike group it was meant for.

A plan for the next new hire or department
Adding someone to the system afterward is usually a matter of consulting the existing chart and issuing them a copy of the authorized key their role already calls for, rather than opening the whole hierarchy back up. A genuinely new combination is only usable on doors whose cylinders are pinned to accept it, so the same chart shows whether that means picking an existing bitting or scheduling a repin, keeping the decision informed rather than improvised.

What affects the quote
- 1
Any optional upgrade chosen along the way
Some businesses use the project as an opportunity to also upgrade a door closer, add a keypad to one entry, or reinforce a strike plate. None of this is required for the master key system itself, and each optional item is quoted as its own line.
- 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
Administrator training and handover time
Walking the named administrator through the chart, the issuance process and how to handle a future lost key or new hire takes a defined amount of time on the day of handover, and a more detailed walkthrough for a larger, multi-level system takes longer than a simple one.
Same fees day, night or weekend.
Master Key System Design: questions
How is accountability maintained when several people hold different levels of keys?
Through the chart and issuance log rather than memory. Each level is tied to named roles or people, each key is marked to reflect its level rather than the door it opens, and any change of hands is recorded with a signed receipt. That record names every authorized holder for a door, though it can only account for a key that was never copied, loaned or picked up by someone outside that list.
What records should I keep once the system is installed?
The keying chart itself, a log of which key or fob was issued to which person or role, and receipts signed when keys change hands. Together these let the business answer, at any point, who currently holds which level and when it was issued, rather than relying on memory once the locksmith who built the system is no longer involved.
What is a master key system, in plain terms?
It is a set of keys arranged in levels rather than issued one at a time. An individual change key opens one door, or a small group of doors keyed alike. A sub-master opens a defined group of doors, such as everything on one floor. A single top-level master opens the whole set. The levels are designed around who actually needs each one, then cylinders are pinned to match, so the physical keys follow an organization's real structure instead of years of informal copying.

What the census means at the door
30%
Newer homes. About 30% of homes in Newmarket were built in 1980 or earlier, according to the 2021 Census.
In newer developments the hardware is often the same finish and style from house to house. A locksmith can offer upgrades that match what is already there, so a stronger cylinder or a new lever set fits in without looking like an afterthought.
60%
A mix of homes. Single-detached houses make up about 60% of homes in Newmarket (2021 Census).
Where housing types are mixed, the same lost-key call means different things. In a house, rekey every door on the property. In an apartment, rekey the suite door and check with management about the common entrance. The locksmith asks which it is first.
