Licensed and insured

Your price comes first
Approve the written price on a tablet before work begins.
When keys stop fitting the way you work
Card and fob entry makes sense when several people need access and that list changes. These are common reasons managers make the switch.
Staff changes
An employee leaves or joins the team. Change who can enter without replacing the door's lock.
Shared workspaces
Several employees use the same entrance. Each person can carry a card or fob rather than another metal key.
Multiple departments
Different teams need different doors. A managed system can organize access across a small commercial property.
Office turnover
A new tenant or office manager takes over. Review the existing credentials and who should retain access.
More than one entrance
A business has separate staff, storage or service doors. Plan which entrances need electronic credentials.
Keys are hard to account for
Too many physical keys are in circulation. Move routine staff entry to credentials that management can remove.
The hardware and setup we handle
We match the entry hardware to the door and the number of people using it. The work includes showing your manager how to use the system.
Readers and electric strikes
We fit card or fob readers with compatible electric strikes, allowing an authorized credential to release the door.
Standalone credential locks
For a single entrance, we install locks that read a card or fob without requiring a building-wide system.
Small managed installations
A small managed system serves up to 16 doors, letting a manager add or remove users across several entrances.
Manager handover
We demonstrate adding and removing users, check operation at each entrance and provide a backup key for every door.

How we price card and fob entry
There is no single price for every card entry installation. We inspect the doors and hardware, then provide a written price for approval before work.
Number of doors
One standalone entrance requires different equipment and labor than a property with several managed doors.
Credential hardware
The selected reader, standalone lock or electric strike affects the parts and installation required.
Existing door condition
We check the lock, latch, door and frame before deciding what can stay and what needs changing.
System scope
A managed installation needs planning for the people and entrances involved. Larger networked work requires a licensed low-voltage contractor.
Service call and scheduling
The $39 service call fee is separate from labor and parts. A $45 after-hours fee is added from 9 PM to 7 AM and on Sundays and major holidays.
From walkthrough to working entry
We start with the doors and the people who use them, not a hardware catalog. Your manager approves the plan before installation.
Tell us how access should work
Call or send a request. Our office asks for the property address, number of entrances, existing locks and who needs access.
Meet us at the property
A technician arrives with photo ID and a work card. We confirm the business owner's or authorized manager's approval before proceeding.
Review the proposed work
We inspect the hardware and prepare a written recommendation and price. You approve the full scope before installation begins.
Test each door together
We install the approved equipment, test entry and locking with your manager, hand over door records and issue an itemized invoice.
Questions before changing to fob entry
The right system depends on your doors, staff and how much control you need. Here are the questions worth settling before installation.
Call (702) 000-0000All questionsCan we remove an employee's fob without changing the lock?
Yes. Access can be removed from the system without replacing the physical lock. We show the designated manager how to make those changes.
Do we need a managed system for just one door?
Not necessarily. Cairn installs standalone locks that accept cards or fobs, as well as small managed installations. We review the entrance and how staff will use it before recommending hardware.
What happens if the electronic entry stops working?
Every door in a Cairn card or fob installation has a backup key. We test the electronic entry and the physical key with the manager before handing over the work.
Can you connect the system to our fire alarm?
Work involving a fire alarm is handled with a licensed low-voltage contractor. The same applies to larger networked access systems. Cairn does not install cameras or alarm systems.
Can you quote a 12-door installation over the phone?
We can discuss the scope and applicable service call fee, but the final price requires an inspection. We assess the doors and selected hardware, then provide a written proposal for your approval.
Other ways to manage who gets in
Access control and keyless entry
Compare card entry with keypad locks, electric strikes and other small-business access options.
Keypad door locks
Use a code rather than a physical credential on a suitable commercial entrance.
Master key systems
Give managers broader access while individual doors retain their own mechanical keys.
Offices
Plan office entry around staff, shared rooms and changes in who needs a key.
Put your entry plan in motion
Request a door walkthrough
Tell us how many entrances you manage. Properties with five or more doors qualify for a walkthrough and written recommendation at no charge.
Call about an urgent lock
If a business door has failed or you cannot get inside, call the emergency line. A dispatcher answers at any hour.
