The challenge
Too many keys and no record of keyholders
The office park had several buildings and too many keys in circulation. Management had no record showing who held each key, making it difficult to account for access across the property.
The problem was not simply the number of doors. Different staff roles needed appropriate access, while the property needed a controlled process for issuing any additional copies.

A key system built around staff roles
Cairn recommended a planned key hierarchy and written records rather than continuing to issue separate, untracked keys.
Survey the buildings
Owen Brandt walked the property to assess the doors and understand the access requirements before designing the system.
Assign keys by building
Each building received its own master key level, allowing staff access to be organized by building rather than by individual door.
Separate staff responsibilities
Sub-master access was arranged for maintenance and management, with restricted keys used to control duplication.
Document every door
A door-by-door record was prepared for management, giving the property a written reference for its new key system.
From walkthrough to handover
The project followed Cairn's commercial process, with planning before installation and records delivered when the work was complete.
Review the property
Owen completed an on-site walkthrough of the office park and its multiple buildings.
Prepare the key plan
The proposed hierarchy matched building access with the separate needs of the property's maintenance and management staff.
Install outside business hours
The approved master key system was installed after hours, following the property's agreed work schedule.
Hand over the records
The completed door record was delivered to management along with the procedure for requesting additional restricted keys.
A clearer record of every key
The finished system changed how the office park issued keys and accounted for access, without requiring staff to carry a separate key for every door.
One key for each staff role
Staff could use a single key appropriate to their responsibilities instead of carrying a collection of individual door keys.
Copies require approval
Additional restricted keys could be issued only through a signed request, giving management control over duplication.
A documented handover
Management has a door-by-door record. Before this project, there was no record of who held the keys.
“We had keys circulating between several buildings and no useful record of who was holding them. Owen walked the property, and Cairn installed the new system after hours. Our staff have keys assigned by role, and extra copies require a signed request.”
