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.
Beyond convenience, master key system design is a security decision. It sets out who can duplicate a key, how many levels of access exist, and what scope the chart assigns to a lost key at each level, from one door up to the whole property for a top master. A restricted or patented keyway is often part of the answer, since it cuts down on copies being made anywhere other than through the record the owner controls. The result is a system where access matches role, duplication is tracked, and every missing key's designed scope is already known rather than guessed at afterward.

Master Key System Design · Innisfil
Scene 1
Before anything is redesigned, the locksmith reviews the keys already in circulation: how many exist for each door, which ones are stamped or coded in a way that identifies what they open, and which staff members currently hold more access than their role calls for. This review often surfaces the exact problem the new system needs to fix, whether that is a master key copied one time too many or a department that was folded into another without anyone updating who could get in.
Scene 2
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.
Scene 3
Because spare capacity was planned into the keying platform from the start, a realistic new door, tenant or hire usually fits into the existing chart without disturbing levels that are already in use. This is the practical payoff of building the system with growth in mind rather than filling every available combination on the first day: expansion becomes an addition to the record, not a reopening of it.

The current chart shows exactly which doors that level was designed to reach, which for a lost top-level master can mean the whole property rather than one group. Depending on how the key was lost and who else already holds that level, the usual options are repinning the affected cylinders and reissuing keys to the remaining holders; a restricted keyway lowers the odds of an unauthorized copy being cut but is not proof that one has not been made. Without a current chart, the first task is reconstructing that scope.
A restricted or patented keyway limits who can cut a copy of your keys to whoever holds the manufacturer's authorization record, rather than any hardware counter. It suits doors behind which cash, records or controlled supplies sit. A standard keyway is simpler to administer and works well for lower-risk doors where duplication control matters less.
Sometimes, but it depends on the keyway and pinning platform each brand uses; some are compatible with one another and some are not. Where a mix already exists on a property, the assessment identifies which cylinders can be brought into a single hierarchy and which need replacing with a matching platform so every level pins correctly across the whole set of doors.
