Key fob programming in Provo starts with finding out what is actually wrong, because a fob that quits is often a tired battery, not a dead fob. When a remote or smart key really does need programming or replacing, we come to your vehicle, pair new or existing fobs for most makes and models, and test every button and the engine start before we leave.
"Key fob" covers three different devices, and each one programs differently.
A blade with lock and unlock buttons in the head. Inside are two systems: a transponder chip the immobilizer reads before the engine will run, and a transmitter for the doors. Many vehicles program them separately, so a key can start the car while its buttons do nothing. Flip keys work the same way.
A standalone remote on the ring beside a plain or chip key. It locks and unlocks, but programming it never touches the immobilizer, which makes it the simplest fob to add.
The car senses the fob in your pocket, unlocks at the handle, and starts with a button. Because the fob handles both entry and starting, it is registered to the immobilizer, usually through the diagnostic port. When every key is gone, the job becomes car key replacement.
Rule out the battery before paying for a new fob. Coin cells fade slowly, and the signs are predictable:
A real failure looks different:

Call (801) 555-0142Programming a fob you already own is one job. Replacing hardware is another, and you have choices.
| Option | What it is | Upside | Watch for |
|---|---|---|---|
| Factory (OEM) fob | Made by or for the vehicle maker | Exact fit, finish, and range | Highest price |
| Aftermarket fob | Third-party fob built for your model | Lower cost | Quality varies; must match the FCC ID and frequency |
| Used factory fob | A factory fob from another car | Cheapest factory part | Many fobs lock to the first car they are programmed to |
| New shell only | Fresh case and buttons; your electronics move over | Keeps your working chip and board | Fixes physical damage only |
If you bought a fob online, we can try to program it, but we cannot promise it will take. A fob with the wrong frequency, the wrong chip, or a lock from a previous car will not program no matter who tries, so read us the numbers before you buy. For lockouts, ignitions, and other vehicle work, see our automotive locksmith services.
For a national benchmark, Fixr's 2025 cost guide lists locksmith key fob programming at $50 to $200. That is a national range, not our rate. We give you the exact price on the phone, including the fob if you need one, before we head out.
Cold is hard on the coin cells inside fobs, which deliver less power as the temperature drops. NOAA's 1991 to 2020 normals for the Provo BYU station put the average January low at 23.8°F and the December low at 24.4°F, so a battery that was borderline in October can quit on the first cold morning.
We program and replace fobs wherever the car is parked: a driveway in Oak Hills or Rivergrove, a stall near the BYU campus, or a lot downtown off Center Street. If you have a spare fob, try it before you call. If the spare works, the problem is the first fob, not the car.
Why Choose Us
Battery first
Plenty of fobs that seem dead just have a tired coin cell. If your symptoms sound like a battery, we tell you on the phone to try a fresh one before we drive out. At the vehicle, we test the fob and its cell before quoting any hardware. You pay for a new fob only when the old one has truly failed, has been lost, or you want an extra.
Every button
A fob that unlocks the doors but will not start the engine is half a job, and so is a proximity fob that starts the car but will not open the trunk. After programming, we test lock, unlock, trunk, panic, remote start where equipped, and an engine start with every fob you have. If a lost fob can be removed from the car's memory, we remove it in the same visit.
Most makes
Dealers usually want the car at the service department during business hours. We bring the programming equipment to the vehicle at any hour, for most makes and models, including push-to-start systems. If your vehicle is one of the few that only a dealer can program, we tell you on the phone instead of charging for a trip that cannot fix it.
Our Promise
Locksmithing runs on trust. These are the commitments you can hold us to on every call, from a 2 a.m. lockout to a full office rekey.
We quote on the phone, then confirm the total on site before any work begins. If the job turns out to be different than described, you approve the new number before we continue.
We confirm you live at the address or own the vehicle before we open anything. It takes about a minute, and it is the same check that protects your home from someone else claiming to be you.
We pick, bypass, or decode before we ever consider drilling. If a lock truly has to be drilled, we explain why and get your OK first, and we can replace it on the spot.
Nights, weekends, and holidays use the same phone number. You get a person, a price, and an arrival estimate, not a voicemail box.
FAQ
Sometimes. Some older vehicles have an owner procedure for adding a separate remote, usually key turns and button presses listed in the manual, and some let you add a key yourself if you already have two working ones. Most chip keys and push-to-start fobs need a programming tool on the diagnostic port.
Usually not. Most fobs keep their programming through a battery change. A few remotes lose sync and need reprogramming afterward. If yours stopped right after a swap, first check that the new battery is the correct size and is seated with the correct side up.
The engine keeps running, and the dash warns that no key is detected. Once you shut it off, it will not restart until the car reads the fob, which on many models means holding the fob against the start button. Your owner's manual shows the backup spot for your car.
Often. If the buttons are worn through or the shell is cracked but the circuit board and chip still work, we move them into a new shell and cut its blade to match your key. With the original board and chip, no programming is needed, so it costs less than a new fob.
