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
Underneath the plastic case, a fob is a small radio and, on most modern vehicles, a chip the immobilizer reads before allowing the engine to start. Programming has to satisfy both halves: the buttons that lock and unlock, and the hidden authorization that lets the key turn the engine over. A fob that only handles one half explains why some buttons keep working while the vehicle still refuses to start, and programming addresses whichever half was never registered correctly.
How the visit goesThe 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. A fading battery inside the fob is the likely reason, even though the fob itself looks and feels completely normal.

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.
Testing every function before calling it finished
A fob is more than one signal, and each one is checked in turn once registration finishes: locking, unlocking, the trunk or hatch release, the panic alarm, and where the vehicle has it, passive entry, tested by whatever action that vehicle actually needs, approach, a handle touch, grip or button press, and remote start from a distance. The mechanical backup blade, if the fob has one, is tested in the door; on many push-button-start vehicles that blade opens the door only, and starting still needs the electronic fob recognized at the switch. Skipping a function to save a moment means discovering the gap days later, so each one is confirmed while the tools and the vehicle are still right there.
What to do the next time a fob goes missing
A single lost fob is a manageable problem: the vehicle's memory can be told to stop recognizing its electronic authorization, following that model's own procedure. A mechanical blade built into the fob is a separate question, addressed by rekeying the matching lock where that risk needs ruling out too. Reporting a loss promptly, rather than hoping the fob turns up, is the habit worth keeping, since a fob nobody has removed from the system keeps working for as long as it sits in a stranger's drawer or a lost bag somewhere.

What affects the quote
Same fees day, night or weekend
1Battery and hardware needs uncovered during the visit
A fob that turns out to need only a battery or a replacement shell, once opened and examined, is a smaller job than full electronic replacement, and the quote adjusts to reflect what was actually needed.
2Condition of the fob already in hand
A fob with a cracked shell, worn buttons or a fading battery may need parts beyond programming alone, and any repair work is priced as its own line rather than folded silently into the visit.
3How 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.
Key Fob Programming: questions
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.
Can a cracked fob shell be fixed without replacing the whole fob?
Often, yes. A replacement shell built for the same internal electronics can be fitted around the working circuit board and buttons, so a fob that still functions but looks and feels worn out gets a new case rather than a full replacement. This only applies when the electronics inside are still sound; a board damaged by water or impact may need the fob itself replaced.
What happens to my old fob once it's replaced?
A fob you hand over because it is no longer wanted is simply left with you, since it belongs to you regardless of whether it still works. If the old fob was actually lost rather than in your possession, there is nothing to hand over; instead its electronic authorization is removed from the vehicle's memory following that model's procedure, so its remote and starting functions no longer work for whoever does have it, though a mechanical blade built into it can still open an unchanged door lock.

For a household in Toronto the common requests are a rekey after moving in, a lockout, a deadbolt that grinds, and a lock that finally needs replacing. For a business they are storefront hardware, staff key control and exit devices. Both lists, and a few less common jobs, are laid out here.
