Master Key System Design
The new wing was built with its own brand of cylinder, so the two-year-old keys from the original building do not open a single door in the addition. Staff are now carrying two separate key rings just to move around one workplace.
Master Key System Design
In plain words
A property that expects to add doors, departments or locations benefits from a master key system built with room to grow. Master key system design accounts for that from the outset: the keying platform and combinations chosen leave spare capacity for realistic future openings, rather than filling every available combination on the first day. That way, a new office, a new hire, or a newly leased unit can usually be added to the existing chart instead of triggering a redesign of levels that are already in use elsewhere in the building.

How the visit goes
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.
Fitting or replacing hardware to match the plan
Cylinders that can join the new hierarchy without modification are pinned in place; those that cannot, whether because of age, a mismatched keyway or simple wear, are replaced with compatible hardware chosen to match the finish and function already on the door. Locksets on a barrier-free path of travel are fitted with lever or paddle-style hardware that can be operated with a closed fist, keeping those doors usable for everyone while still carrying their assigned level in the same hierarchy as the rest of the building.
Care that keeps the hierarchy intact
A little routine care keeps a master key system working the way it was designed. Cylinders should get whichever lubricant the cylinder maker actually recommends, since that varies by manufacturer and some rule out graphite while others call for a light oil, and a key that starts needing a wiggle is worth attention before it is forced or breaks off. None of this maintenance touches the pinning itself, so the hierarchy stays exactly as documented on the chart through years of ordinary use.

1Testing 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.
2Documentation and chart detail requested
A simple chart listing levels and holders is the baseline. Some businesses want a more detailed record, cross-referenced by department, room number or staff role, which takes additional time to prepare and is quoted as part of the documentation work.
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
Can a master key system be expanded later without redesigning it?
Usually yes, if spare capacity was planned into the keying platform from the start. A new hire is normally handed a copy of the bitting their role already calls for, and a realistic new door can be pinned to accept a combination already reserved for that purpose. A system pinned to its absolute limit on day one has less room to grow, and adding a level to existing doors later can mean repinning cylinders that are already in daily use.
What should I have ready before the assessment visit?
A rough list of who currently has access to which doors, any existing keys or cylinders you can point to, and a sense of upcoming changes such as new hires, a department split, or a unit due to open. None of this needs to be exact; the assessment is partly built around confirming or correcting whatever the business already assumes about its own access.
Can my existing locks be used, or do I need all new hardware?
Many existing cylinders can join a new hierarchy as they are, once their keyway and condition are confirmed compatible. Others, particularly older or mismatched hardware, are replaced so the whole system pins cleanly without cross-keying. The assessment identifies which doors fall into each group before any work begins, so the plan reflects what is actually on the property rather than assuming everything needs to change.
