Restricted keys for your business
Keep business key copies under a defined approval process. Cairn installs and services restricted key systems across the Las Vegas valley.
- Patented keyways limit who can supply key blanks
- Each issued key is stamped and recorded
- New keys require a signed request from an approved contact

Answered day and night
A Cairn dispatcher answers every day of the year.
Licensed and insured
Employee technicians carry photo ID and a police work card.
Your price comes first
Approve the written price on a tablet before work begins.
When copying keys needs tighter control
Ordinary keys can be copied without the property manager knowing. A restricted system creates a record of who is allowed to request additional keys.
Keys pass between employees
A staff change should not leave the business guessing how many copies were made. Restricted keys give management a defined issuance process.
Several tenants share a property
Property managers can administer key requests for separate spaces through named contacts rather than informal copying.
Managers need wider access
Pair restricted cylinders with a master key arrangement so management access and individual door keys follow the same issuing rules.
Office records need key control
Keep the decision to issue keys for records rooms with the business contacts responsible for access.
Multiple departments use keys
Separate the people permitted to request duplicates from the employees who use the keys to open their assigned doors.
The business changes ownership
A new owner can establish the account contacts who approve future copies instead of relying on a previous key distribution arrangement.
A key system with an issuing record
Restricted key control involves the cylinder, the key blank and the records behind each issued copy. All three matter.
Controlled key blanks
The patented keyway uses blanks supplied only to the contracted locksmith, not through ordinary retail key-cutting counters.
Identified keys
Each issued key carries a stamp and is entered in the account's key records.
Documented release
Additional keys are released only to approved account contacts following a signed request. The records are kept in a locked file.
Compatible system planning
We assess whether the restricted cylinders should work independently or as part of a larger master key hierarchy.

What determines system pricing
Restricted key systems are priced after inspection and hardware selection. The separate $39 service call fee applies, and the full written price requires your approval before work.
Doors included in the system
The proposal accounts for how many individual cylinders will become part of the restricted arrangement.
Hardware selection
Cylinder grade and product choice affect the price. We service Medeco, Mul-T-Lock and Schlage Primus.
Existing lock compatibility
We inspect the installed locks to determine which hardware can remain and what must change to accept the selected system.
Master key requirements
A system with management keys and separate department access requires additional planning beyond individual restricted cylinders.
Installation schedule
Work can be scheduled around your business. A $45 after-hours fee is added between 9 PM and 7 AM, and also on Sundays and major holidays.
How we establish your key control
The work begins with the doors and the people responsible for them. Key issuance rules are part of the plan, not an afterthought.
Describe the property
Call or request a visit. Our office asks about the address, doors, existing hardware, key holders and who will approve future key requests.
Verify the decision maker
At the property, the locksmith presents ID and a work card, then confirms the authorized contact and written approval for lock changes.
Review the proposed system
We inspect the locks, identify the appropriate cylinders and explain the keying plan. You approve the written price before installation.
Install and hand over
We fit the approved hardware, test the keys with management and hand over the door records and itemized invoice.
What to know about restricted keys
The central distinction is not how the key looks. It is who can obtain another one and how that request is documented.
Call (702) 000-0000All questionsCan an employee copy a restricted key at a hardware store?
The patented keyway uses blanks available only to the contracted locksmith. A hardware store or retail key kiosk does not have those blanks to make an ordinary duplicate.
Who is allowed to request another key?
The business names its authorized contacts on the account. Cairn releases additional keys to those contacts only when a signed request is received.
Can restricted keys work with our master key system?
Yes. Restricted keyways can be used on their own or incorporated into a compatible master key system. We review the existing cylinders and the planned access levels before proposing the arrangement.
What records do you keep of our business keys?
Each issued key is stamped and logged. Cairn stores the key records in a locked file and follows the account’s authorized contact list when releasing additional keys.
Do restricted keys mean we must replace every lock?
That depends on the cylinders and hardware already installed. We inspect the locks and identify which components can remain before preparing a written proposal.
Plan the rest of your access system
Master key systems
Arrange individual door keys and management keys within a planned access hierarchy.
Commercial rekeying
Change which keys operate existing commercial cylinders after staff or tenant turnover.
High-security locks
Review higher-grade cylinders and lock hardware for business entrances and sensitive rooms.
Property managers
Coordinate door access, resident turnover and key requests across properties under management.
Put key duplication under your control
Request a property walkthrough
Discuss your doors, key holders and approval process. Businesses with five or more doors can request a walkthrough and written recommendation at no charge.
