Key Fob Programming
The remote clicks the way it always has, but the vehicle no longer locks, unlocks or answers with its usual chirp. Nothing on the dash reacts either.
Key Fob Programming
In plain words
Fobs age the way most electronics do: batteries fade, buttons stick, cases crack after years on a keyring. This kind of work often overlaps with simple repair, since a fob that has stopped responding is frequently a battery issue rather than an electronic failure, and a cracked shell can be replaced without touching the electronics inside it at all. Sorting out which problem is which, before assuming a full replacement is needed, is part of the visit.
How the visit goesA replacement fob just arrived in its box, shiny and untouched. It looks identical to the one that has ridden on the keyring for years, but the car ignores it entirely: no lock click, no start authorization, nothing. It needs to be introduced to the vehicle first.

How the visit goes
Whether this vehicle keeps its own gatekeeper
Some manufacturers build a security gateway into newer models specifically so that only an authorized, model-approved procedure can add a fob, guarding against the same equipment being used on a vehicle that was never authorized for the work. Before committing to a mobile visit, the vehicle's year, model and security system are checked against what that gateway allows. Where the manufacturer restricts the procedure to a dealer or a registered access pathway, that is identified early and explained plainly, rather than discovered halfway through an attempt that cannot finish on site.
Removing a lost fob from the vehicle's memory
Adding a new fob solves half the problem when the old one is genuinely missing rather than simply misplaced at home; the other half is telling the vehicle to stop recognizing the fob that is out there somewhere. The procedure follows that model's own lost-key route: some delete just that one fob's authorization and leave the others untouched, while others first erase every known credential and then relearn the ones you keep, so a household with three fobs and one lost one still ends the visit with two working fobs and a lost one that no longer operates the vehicle electronically.
Leaving with fobs that have been proven, not assumed
The visit ends with every fob in hand tested against the vehicle rather than handed over on faith: each has locked, unlocked and started the car in front of the person receiving it. Anyone in the household who will carry a fob knows which one is theirs and that it has already done its job at least once. A short note of what was registered, and on what date, is worth keeping somewhere so a future visit or an insurance question has something concrete to refer to.

What affects the quote
Same fees day, night or weekend
1How many fobs are being registered
One additional fob for one driver is a smaller job than registering fobs for an entire household or a small fleet, and the number of fobs involved shapes the quote.
2Remote start and other added features
A fob supporting remote start, a separate trunk release or additional convenience buttons involves more to register and test than a fob limited to locking and unlocking, and the quote reflects that scope.
3New fob versus an eligible reused one
A brand-new fob sourced for the visit is priced differently than programming a used or reused fob the household already owns, once that fob has been confirmed compatible with the vehicle.
Key Fob Programming: questions
Do I need to bring my car anywhere, or does the work happen where it is?
The vehicle generally stays where it is parked, since the equipment used for programming travels to it rather than the other way around. What matters more than the location is that the vehicle itself is present for the visit, since most procedures read information directly from the car as part of registering the new fob.
What if my vehicle turns out to need dealer-only programming?
Some manufacturers restrict fob programming to a security-gated procedure that only a dealer system or an approved access pathway can complete. When a vehicle falls into that category, the visit identifies it early, explains what the vehicle specifically requires, and documents anything already confirmed, such as a compatible fob, so the eventual dealer visit is not starting the diagnosis over from nothing.
I bought a used car with only one fob. What are my options?
Ownership of the vehicle is confirmed first, since a fob is only added for someone who can show they now hold the vehicle. From there, an additional fob is sourced and registered alongside the one you have, or, if you would rather not rely on a single fob at all, a second and third can be added in the same visit.
