Smart-lock installation at your door
A smart lock should turn without fighting the door. Cairn fits the hardware, checks the bolt alignment and sets up access with you before leaving.
- We install locks you buy or locks we supply
- Phone pairing and user code setup included
- 12-month workmanship warranty
The right lock for the way you enter
Smart locks differ in how they accept a command and communicate with your phone. We install these six types and check the door before fitting one.
Keypad deadbolts
Enter a user code at the door instead of reaching for a key. Codes can be added or changed as access needs change.
Wi-Fi locks
Connect through the lock's supported app and network. We check the signal where the lock actually sits, not just inside the house.
Bluetooth locks
Pair with a compatible phone for nearby control. Bluetooth connection and remote internet access are not the same thing.
Smart-home compatible locks
Models that work with Apple Home, Google Home or Amazon Alexa. Compatibility depends on the particular lock and its supported setup.
Smart lever locks
An electronic access option built into lever-style door hardware. We check the existing door preparation before installation.
Retrofit smart locks
These fit over a compatible existing deadbolt, leaving its exterior hardware in place. The existing lock must operate properly first.
Six checks before the lock goes on
A compatible app does not mean a compatible door. These measurements and operating conditions determine whether the hardware will fit and work properly.
Door thickness
Most residential smart locks fit doors from 1 3/8 to 1 3/4 inches thick. We measure rather than assume.
Backset measurement
The distance from the door edge to the lock center is commonly 2 3/8 or 2 3/4 inches. The replacement must suit that measurement.
Bore hole size
The existing opening must accommodate the new lock body and mounting hardware. We inspect it before changing anything.
Free bolt movement
The bolt must extend and retract without someone lifting or pushing the door. A motor should not be compensating for poor alignment.
Wi-Fi at the doorway
For a Wi-Fi model, the network needs to reach the actual installation point. Signal inside the nearest room may be different.
Direct sun exposure
We consider how much sun hits the exterior keypad. Las Vegas heat can affect the finish, display and battery life.
We fit the lock and set up access
Installation includes the mechanical work and the initial setup with you present. The administrative account belongs to you, and Cairn retains no access codes or logins.
Fit and secure the hardware
We position the exterior and interior components, fit the lock to the prepared door and check that the mechanism moves correctly.
Adjust the strike
We check where the deadbolt enters the frame and adjust the strike as needed so it can extend without binding.
Pair your phone
We walk through the supported app connection on your device and confirm that the lock responds to the setup.
Set up user codes
We help you add and test the initial codes. You control them afterward without sharing your administrator credentials.
Explain backup access
We show you how to replace the batteries and use the backup key where the model provides one.
Two ways to supply the hardware
Already bought a smart lock? We can install customer-supplied hardware or provide the lock as part of the job. The warranty responsibility differs.
A lock you bought
We inspect the lock you purchased and your door before agreeing to the installation. The hardware itself remains your responsibility.
- We check your purchased lock fits before installing
- Installation labor warranty applies
- Hardware claims stay with you and the seller
A lock we supply
We supply the selected hardware and install it after checking the door. You have one service contact for the work and the supplied lock.
- Hardware selected for the door
- Installation workmanship is warranted
- We handle the manufacturer's hardware claim
The workmanship warranty covers faults caused by our installation, not door movement, batteries or external app and Wi-Fi problems. Hardware warranty terms vary.
Electronic access or a regular key
Both choices can serve a home well. The difference is how you want to manage access and how much electronic maintenance you want to take on.
Smart lock
A smart lock gives you electronic access options, with batteries and compatible devices becoming part of ordinary lock maintenance.
- Keypad or supported phone access
- User codes can be changed
- Batteries and electronics need attention
Traditional deadbolt
A conventional deadbolt uses a physical key and does not depend on a battery, phone connection or electronic control.
- Physical key operation
- No battery replacement
- Rekeying can change who has access
A properly fitted lock matters in either case. A sticking door can cause trouble for electronic and mechanical hardware alike.
Rentals and vacation rentals
Manage rental access without spare keys
For a rental property, a keypad lock can make guest turnover less dependent on collecting and distributing physical keys. A new code can be assigned for each guest, with separate codes for cleaners and staff. We install the hardware and help establish the initial access setup with the owner or authorized manager.
Lock changes on a rental require the owner's or manager's approval. Owners manage their own rental licensing and access policies; Cairn handles the lock and its supported setup, not short-term rental rules or property management software.
- Change guest codes between stays
- Separate access for staff and cleaners
- Keep account control with the owner or manager
Las Vegas heat changes battery life
A smart lock's motor uses more power when it has to push a bolt against a dragging door. Add direct desert sun, and batteries can need attention sooner. These checks help distinguish a maintenance issue from a failing lock.
- West and south sun can fade keypads and shorten battery life
- Use name-brand alkaline batteries; check twice yearly
- A swollen or dragging door makes the motor work harder
- Keep the backup key where you can reach it if batteries die
From door check to working lock
The installation follows the same inspection, authorization and pricing process as our other residential lock work. You approve the work before we start.
Tell us about the door
Request planned installation or call. We ask for the address, door type, existing lock and any model you have purchased. The office arranges the visit.
Confirm access and authority
A uniformed technician arrives in a marked van with photo ID and a work card. We verify your identity and authority to change the lock.
Inspect and approve the price
We check the door and hardware, then give you a written price for approval. Any drilling, cutting or replacement requires separate approval.
Install, test and document
We fit the lock, test its operation with you and confirm the door latches. Your itemized invoice separates the service call fee, labor and parts.
Smart-lock brands we service
We service Schlage Encode, Kwikset Halo, Yale Assure, August and Level smart locks. Installation depends on the specific model and the condition of the door.

“We had a keypad deadbolt installed at our house in Henderson. The technician found that the bolt was catching against the strike, adjusted it and then helped us set up the phone and codes. We tested it with the door closed before he left.”

Questions before fitting a smart lock
The lock model matters, but so does the door it goes into. These are the practical questions to settle before scheduling an installation.
Call (702) 000-0000All questionsCan you install a smart lock I already purchased?
Yes, provided the lock is suitable for your door. We warrant our installation labor, while claims involving customer-supplied hardware remain with the manufacturer or seller.
Will a smart lock fit the holes in my existing door?
That depends on the door thickness, backset and bore hole dimensions. We inspect those measurements before installation and explain any changes the door would need.
My deadbolt sticks unless I pull the door. Can you still install one?
The bolt needs to move freely before a motor operates it. We inspect the door and strike alignment and explain what adjustment is needed before fitting the new hardware.
Will you have access to my lock after setting it up?
No. You retain the administrator account and control your user codes, and Cairn does not keep your codes or login credentials. We help with the initial setup on your device.
Can I use a smart lock on a vacation rental?
Yes. We install keypad and smart locks that support separate guest, staff and cleaner codes, with new codes for each stay. The property owner or authorized manager controls access and is responsible for rental licensing.
Why do my smart lock batteries run down sooner than expected?
Direct heat can shorten battery life, and a dragging bolt makes the motor draw more power. Check the door alignment and use the alkaline batteries recommended for the lock.
What happens if the installation has a problem later?
Our 12-month workmanship warranty covers a problem caused by the installation. It does not cover batteries, shifting doors or external Wi-Fi and app issues; manufacturer hardware warranty terms depend on the lock.
