Master Key System Design in Mount Dennis
On the warehouse floor, a shift supervisor's key opens the loading dock, the tool crib and the manager's office, though only the dock is really part of the job. Nobody planned it that way; the key was simply copied from whichever one was closest at hand.
Master Key System Design
In plain words
Many commercial properties end up with keys copied from other keys over years of staff changes, until nobody can say with confidence what a given key actually opens. Master key system design starts from the opposite direction: an approved list of roles and openings comes first, and the keying follows it. Doors that genuinely need to share access are grouped under a sub-master; doors that do not stay on their own key. Once the hierarchy is agreed, the cylinders are pinned to match it, tested lock by lock, and handed over with a plain record so the business always knows which key belongs where.
How the visit goesA new hire at the shop gets handed whatever spare key happens to be in the drawer, and it turns out to open the stockroom, the back office and the safe room all at once. The owner realizes nobody actually decided who should open what.

How the visit goes
Duplication and how tightly it needs to be controlled
Some businesses are comfortable with standard key blanks that any hardware counter can cut; others, especially where records, cash or controlled supplies sit behind a door, want a restricted or patented keyway that limits duplication to a record the owner controls. This is decided door by door rather than for the whole property at once, since a stockroom and a records room rarely carry the same risk. The answer shapes both the hardware chosen and how future copies of any given key will be requested and tracked going forward.
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
Same fees day, night or weekend
1Working 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.
2Testing scope before handover
Testing every cylinder individually and then testing each master and sub-master across its full group takes time proportional to how many doors and levels exist. A larger hierarchy with more levels to verify against more doors adds to that testing time.
3Any 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.
Master Key System Design: questions
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 is tested before the keys are handed over?
Every cylinder is tested on the bench against its assigned keys, then again once installed: the change key on its own door, the relevant sub-master across its whole group, and the top-level master across every door in the system. Any lock that responds to a key it should not is corrected before handover rather than left for the owner to discover later.
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.
