Call (702) 000-0000Contact and request serviceGeneral and emergency
Can I call Cairn for a lockout in the middle of the night?
A Cairn dispatcher answers the emergency line 24 hours a day, every day, including holidays. Emergency calls include home, business and vehicle lockouts, broken keys, failed locks and urgent lock changes within our service area.
How long will it take a locksmith to reach me?
Daytime arrival in the Las Vegas valley is typically 20 to 40 minutes. The dispatcher estimates your arrival window based on the nearest van’s location, traffic and time of day. That window is an estimate, not a promise.
What should I have ready when I call about a lockout?
Give the dispatcher your address or nearest cross streets, explain which door or vehicle is locked and describe what happened. While waiting, stay in a safe, well-lit place and avoid forcing the lock or door.
Will you have to drill my lock to open the door?
The technician examines the lock and uses a non-destructive entry method when its condition allows. Drilling is reserved for situations where other methods are unsuitable, and you must approve both the drilling and replacement price first.
What if a child or pet is locked inside a hot car?
Call 911 first if a child, pet or vulnerable person is trapped and in danger. Las Vegas summer highs exceed 110°F, and the temperature inside a closed vehicle can reach dangerous levels in a very short time.
Who will come to my home when I request a locksmith?
Cairn sends its own W-2 technicians, not home-service subcontractors. You receive a text with the assigned technician’s first name, photo and van number, and the technician arrives in uniform with photo ID and a locksmith work card.
Residential
Should I rekey my locks or replace them?
Rekeying changes the cylinder so previous keys no longer operate it while keeping the existing hardware. Replacement is more suitable for worn, damaged or low-grade locks, or when you want different hardware or a smart lock.
Can my front door, back door and garage entry use one key?
They can share a key when their cylinders have compatible keyways. We check the existing hardware first because different brands and cylinder types cannot always be keyed alike.
Do I need to change the locks after buying a newly built home?
New construction may have locks operated by a builder’s construction key. Rekeying after closing gives you a new set of working keys without automatically replacing hardware that is still in good condition.
Can I have the locks changed if I rent my home?
A rental lock change requires approval from the owner or property manager. We also verify your ID and lease, or obtain confirmation from the landlord or manager, before proceeding.
Can you replace the lock on my mailbox?
We work on locks belonging to customers who own their private mailboxes. Locks on USPS-owned cluster mailbox units must be handled by the Postal Service.
Do you repair gate locks and sliding glass door locks?
Yes. We service gate locks, sliding glass door locks and secondary locking hardware, and check for binding or alignment problems that can keep a latch from engaging.
Commercial
How does a master key system work for a business?
A master key opens the doors assigned to it while individual doors retain their own keys. We plan access by person, department or building and account for doors that should remain outside the master system.
Can I stop employees from making unauthorized key copies?
A restricted key system uses controlled blanks that ordinary key kiosks and hardware stores cannot duplicate. Cairn logs issued keys and releases additional keys only to authorized account contacts on a signed request.
Can you repair a sticking panic bar or a leaking door closer?
We service panic bars, exit devices and surface door closers, including closer adjustments and replacements. Fire-rated assemblies may need review by a fire door inspector or fire marshal before changes are made.
Will you inspect our doors before proposing commercial work?
Our commercial process includes a door walkthrough, written recommendation and proposal. Through December 31, 2026, businesses and properties with 5 or more doors can request a no-charge scheduled walkthrough, not emergency service. Mention the offer when booking.
Can our property management company set up a billing account?
Approved commercial accounts can use purchase orders and net 30 invoicing. Property management accounts have authorized contact lists, work orders submitted by email and monthly statements by property.
Can you work on our doors when the business is closed?
Commercial installations can be scheduled outside operating hours when the business needs it. We establish the scope and schedule in advance, including any applicable after-hours charges.
Automotive
Can you make a car key if I lost the only one?
We replace lost keys for supported vehicles at the vehicle’s location. Making a key when none remains involves additional cutting and programming work, so the vehicle details must be checked before dispatch.
Can you make a spare while I still have a working car key?
Yes. For supported vehicles, a technician can cut and program another key while a working key is available. This generally involves less work than replacing every lost key.
Do you program push-button start fobs?
We service supported smart keys, proximity fobs, transponder keys and remote head keys. Tell us the vehicle’s year, make, model and starting system so we can check programming support.
Can you make keys for BMW, Mercedes-Benz or other European cars?
Many European vehicles from 2015 onward require dealer-only programming, including certain BMW, Mercedes-Benz, Audi, Volkswagen, Volvo and Land Rover models. We check the vehicle on the phone and explain when dealer service is required.
What documents do I need for a replacement vehicle key?
Have your government photo ID and vehicle registration, title or insurance card in the same name ready at the vehicle. Our technician comes to you. If the ownership documents are locked inside, the technician checks them once the vehicle is open.
Can you repair an ignition that will not turn?
We inspect and service ignition cylinders, including repairs, replacements and broken key extraction. The technician checks the cylinder and key condition before recommending the work.
Pricing and authorization
What is the service call fee?
The service call fee is $39 within the standard service area. It pays for travel and inspection, applies to every visit and is separate from any labor or parts charges.
Is there an additional charge for nighttime service?
A $45 after-hours fee applies from 9 PM to 7 AM and on Sundays and major holidays. The dispatcher explains the applicable charges before sending a technician.
Will I see the full price before the locksmith starts?
After inspecting the job, the technician presents a written price listing the charges for the proposed work. You approve it before work begins, and any change requiring a different price must be approved separately.
Can you tell me the total cost over the phone?
The dispatcher gives the service call fee and a price range for the work you describe. The final amount depends on the lock, hardware, door condition or vehicle system and requires inspection.
Why do I have to show ID before you open a lock?
We verify government photo ID and a connection to the property, business or vehicle before completing an entry service. The check helps establish that the person requesting access has authority to enter.
What happens if my ID is locked inside my house?
The technician can open the door and inspect your ID before leaving. If you cannot provide acceptable identification and proof of occupancy, the door is relocked and only the service call fee is charged.
Smart locks and access control
Will you install a smart lock I bought myself?
Yes, if the lock fits the door and can be installed correctly. Customer-supplied locks carry Cairn’s 12-month workmanship warranty on labor only. The lock remains under its manufacturer’s warranty, and you handle product claims because Cairn only handles claims for hardware it supplied.
Does the Las Vegas heat affect smart lock batteries?
Direct sun on west- and south-facing doors can shorten battery life and fade keypads. A dragging deadbolt also makes the motor work harder, so we check door alignment and show you how to maintain the batteries.
Will Cairn keep my smart lock codes or app password?
No. We help pair the lock, add user codes and demonstrate its controls, but the customer retains the administrator account. Cairn does not keep access codes or login credentials.
How do you know whether a smart lock will fit my door?
We check the door thickness, backset, bore opening and whether the bolt moves freely without pushing or lifting the door. For connected locks, we also check the Wi-Fi signal at the entry.
Should my business use standalone keypads or a managed access system?
Standalone locks suit individual openings, while managed systems coordinate access across multiple doors. Cairn handles small managed systems up to 16 doors and works with a licensed low-voltage contractor on larger networked projects.
Safes
Can you open a safe if I cannot get into it?
We inspect safes with lost combinations, failed locks or unresponsive keypads and determine an opening method from their condition. Some require drilling and repair, so an opening method cannot be promised beforehand.
Can you change the combination or keypad on my safe?
We change combinations, replace electronic safe locks and upgrade suitable dial locks to keypads. The technician checks the safe and existing lock before confirming the work.
Can Cairn move a heavy safe?
We handle ground-level safe delivery and moving for units weighing up to 1,000 lb, as well as installation and concrete anchoring. Heavier safes and moves involving stairs are referred to a safe mover.
What proof do I need before you open an inherited safe?
We require photo ID and documents establishing ownership or authority over the safe. For inherited or estate property, have the relevant estate documents available for review.

Which Las Vegas valley communities do you serve?

Do you send locksmiths to Boulder City?
Yes. Boulder City emergency service operates from 7 AM to 9 PM, with overnight calls accepted when a van is available. A $25 travel charge is added to the regular service call fee.
What warranty comes with your locksmith work?
Cairn’s 12-month workmanship warranty covers labor. If a lock we installed, rekeyed or repaired fails because of our work, a technician returns and fixes it at no charge. Keys and fobs we supplied and programmed carry 90 days. Hardware carries its manufacturer’s warranty.
How can I pay for a locksmith visit?
We accept major credit and debit cards, Apple Pay, Google Pay and cash, plus business checks. Payment is collected after completion, and you receive an itemized invoice.
Can I come to your workshop to have a key made?
Our Las Vegas key and safe workshop operates by appointment only and does not have a walk-in counter. Most customer work is handled by a mobile technician at the property or vehicle.
