Many doors, different key holders
A school or church may have teachers, office staff, volunteers and custodians using the same building for different purposes. A key plan should reflect those responsibilities without giving every person access to every room.
Assembly spaces also depend on doors that close, latch and release properly. Cairn assesses the existing hardware and works with the building's authorized representative to plan repairs, replacements and key changes.
- Master and sub-master key systems
- Restricted keys and issuance records
- Panic bars and exit devices
- Door closers and lock rekeying

Hardware for shared buildings
We service the mechanical locks, key systems and door hardware that staff and building users depend on throughout the week.
Master key planning
We plan a master key arrangement that gives designated building managers access across the doors included in the system.
Staff and custodian sub-masters
Sub-master keys can operate a defined group of doors, such as the areas assigned to custodians or other staff.
Controlled key duplication
Restricted cylinders use controlled key blanks so additional copies must be requested through the contracted locksmith.
Assembly door exit hardware
We service panic bars and exit devices, with like-for-like replacement where applicable to the existing door.
Closer adjustments and repairs
We adjust closing and latching speeds and replace leaking closers that no longer operate correctly.
Key holder turnover
When a staff member or volunteer leaves without returning a key, we rekey suitable cylinders so that key no longer works.
A key plan people can manage
The building's leadership decides who should enter each area. Our work starts with those decisions and the condition of the doors.
Changes in key holders
When roles change, identify which keys were issued and which affected cylinders need new keying.
Access by responsibility
Separate room keys and grouped access levels let leadership assign entry according to each person's duties.
Assembly doors and exits
Exit hardware must remain appropriate to the door. We replace devices like for like and identify when a fire door inspector or fire marshal is needed.
A workable service window
We coordinate access to the building around lessons, worship services and scheduled community activities.
Proposals and door records
A written proposal sets out the work for approval, and a door-by-door record documents what was completed.
From door walkthrough to written records
From the first discussion through the final door test, the person responsible for the property stays involved in the decisions.
Name the building contact
An authorized school or church contact calls or sends a request stating which areas are affected, who holds keys and when the building is in use.
Walk the property
We inspect the doors and hardware being considered, including cylinders, latches, closers and applicable exit devices.
Agree on the scope
We prepare a written recommendation and proposal. The building's authorized contact reviews and approves the proposed work.
Schedule and complete
Once authorized, we arrange the work around class or service times and install, adjust or rekey the agreed hardware.
Check and document
We test the completed locks and doors with the property representative, then provide a record of the work at each door.
Questions from building managers
Practical answers for administrators, church officers and others responsible for keys and doors in shared buildings.
Call (702) 000-0000All questionsCan custodians have a key that opens several rooms but not the entire building?
Yes. A sub-master can be planned to open a designated group of doors while individual room keys continue to operate their own locks. We work with the authorized representative to establish the access groups.
What happens when a volunteer leaves without returning a key?
We can assess the cylinders operated by that key and rekey compatible locks so the missing key no longer works. A restricted key system is another option for controlling how replacement copies are issued.
Can you replace a panic bar on our assembly room door?
We service panic bars and exit devices and replace them like for like to preserve the door’s rating. If a fire-rated door needs further review, we refer you to a fire door inspector or the fire marshal.
Can the locksmith come when classes or church services are over?
Yes. We arrange commercial work around class schedules and services, including after-hours work when needed. The authorized contact agrees on the timing before work is scheduled.
Do you provide a record of the doors and keys after the project?
We hand over a door-by-door record when the approved work is complete. For master and restricted key accounts, Cairn also maintains locked key records and requires signed requests from authorized contacts before releasing additional keys.
