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 a fob needs attention
A missing fob, an unreliable remote and a spare-key request are different jobs. Knowing which one you have helps us check the vehicle before dispatch.
You have only one fob
A second key can be added while the existing one still works, avoiding the additional work required when all keys are lost.
Your fob has gone missing
Tell us whether another working key is available. Losing the last one changes the programming work required.
The remote stops responding
Las Vegas heat can shorten fob battery life. The key and vehicle need checking before replacement is recommended.
You need a remote head key
A remote head key combines a metal key and remote buttons in one piece. We cut the key and program it at your vehicle from our van.
You use push-button start
A smart key or proximity fob must be recognized by the vehicle's electronic system before it will start.
Your vehicle may need a dealer
Many European vehicles from 2015 onward require dealer-only programming. We check that limitation before sending a van.
What mobile programming includes
The technician brings the equipment to the parked vehicle, checks the key type and completes the supported programming work on site.
Vehicle and key matching
We use the vehicle details to identify the required key technology and check whether mobile programming is supported.
Fob programming
The technician programs the compatible remote or smart key using equipment carried in the service van.
Spare key addition
When a working key is present, we can add a second compatible key or fob during the visit.
Testing and warranty
We test the programmed key with you. Keys and fobs supplied and programmed by Cairn carry a 90-day warranty.
What your fob programming costs
Smart keys and proximity fobs start at $220, with the $39 service call fee charged separately. The final written price follows inspection and requires your approval.
Vehicle year and make
The year, make and model determine which key technology and programming equipment the vehicle requires.
Type of key or fob
A remote head key and a proximity fob have different parts and programming requirements.
Working key or none
Adding a spare differs from replacing the last key, which involves more work with the vehicle's electronic system.
Second key at the same visit
Get $25 off a second key or fob cut and programmed at the same visit as the first. Offer expires December 31, 2026.
Service time and location
A $45 after-hours fee applies from 9 PM to 7 AM, Sundays and major holidays. Boulder City adds $25 travel to the $39 service call fee.
How we program your fob
We check the vehicle details before sending a technician, then verify ownership and pricing at the car before programming begins.
Give us the vehicle details
Tell the dispatcher the year, make, model, location, key type and whether a working key remains. The VIN helps confirm the correct key.
Verify the vehicle
The technician arrives in a marked van and checks photo ID against the registration, title or insurance card before starting.
Approve the written price
We confirm the required fob and programming work at the vehicle. You review the full written price before authorizing the job.
Program and test the key
We program the key, test its operation with you and provide an itemized invoice showing the service call, labor and parts.
Questions drivers ask about fobs
The answers depend on your vehicle and whether you still have a working key. These details help establish what can be done at the car.
Call (702) 000-0000All questionsCan you program a new fob without taking my car to a shop?
Yes, Cairn programs supported vehicle keys and fobs at the car using equipment in the service van. We can come to a home, workplace or parking lot within the service area.
Can you make a spare while my original key still works?
Yes. A working key lets us add a compatible spare. Get $25 off a second key or fob cut and programmed at the same visit as the first. The offer expires December 31, 2026, is limited to one per job and cannot be combined with other offers. Mention it when booking.
What if I've lost every key to my car?
We handle all-keys-lost replacement on supported vehicles, but it requires more work than adding a spare. Give the dispatcher your vehicle details so we can check support and explain the likely price range before dispatch.
Can you program a fob for my European car?
Some European vehicles are supported, but many models from 2015 onward require programming at a dealer. We check the year, make and model on the call and tell you if that restriction applies before arranging service.
What if the new fob stops working?
Keys and fobs that Cairn supplies and programs have a 90-day warranty. We test the fob at the vehicle before finishing the job, so you can check its operation with the technician.
