Key Fob Programming
A fob went missing weeks ago somewhere between a coat pocket and a parking lot, and a spare has covered the gap since. Everything still opens and starts without trouble, which is exactly the concern: wherever that missing fob ended up, it may still work too.

Losing a fob raises a question a spare doesn't answer on its own: whoever has the missing one can, in principle, still use it. Programming a new fob is only half the service in that situation, because the other half is removing the lost fob's electronic authorization from the vehicle's memory following that model's procedure, which stops its remote and starting functions; a mechanical blade inside it can still open an unchanged door lock, so that lock is rekeyed too where the risk warrants it. The visit closes both problems at once, leaving the household with working fobs and one less fob unaccounted for out in the world.
How the visit goesA new driver has joined the household, and the one existing fob is the only key anyone has ever had cut for this vehicle. Handing that single fob over for the day means someone else is left without a way into their own car.

How the visit goes
- 1
Deciding between adding a fob and starting over
A vehicle with at least one working fob usually calls for adding to what already exists, though some procedures need every retained fob present and re-registered rather than leaving them untouched. A vehicle with no working fob at all follows its own route: many need the key memory reset before anything is added back, while some instead accept an authenticated app or manufacturer service credential without a full reset. Sorting out which situation applies before ordering parts saves a wasted trip and sets the right expectation for how the visit will unfold.

Cutting the mechanical backup that hides inside a smart fob
Most proximity fobs carry a small mechanical blade tucked inside the case for the day the battery goes flat or the electronics fail entirely, and that blade is not something the programming procedure creates on its own. Where a replacement fob arrives without a cut blade, or the household wants a spare cut for the glovebox, the key is cut to the vehicle's original code or matched to an existing working key, then tested in the door's mechanical lock the same way any metal key is tested.

Knowing where this vehicle stands going forward
For a vehicle that turned out to need manufacturer-level access, the household leaves the visit with a clear picture rather than an unresolved gap: what was tried, what the vehicle actually requires, and which fobs are ready to go the moment that next step happens. Nothing sourced during the visit needs to be redone, and the eventual appointment, wherever it happens, starts from a documented position instead of repeating the same identification work from scratch.

What affects the quote

How the fob was obtained
A fob purchased new for this specific vehicle, one bought secondhand, or one inherited from a used-vehicle purchase each carry a different starting point, and that history is part of what the quote considers.

Adding a fob versus starting from nothing
Registering an additional fob while others still work is a shorter procedure than working through that vehicle's own all-keys-lost route, commonly a full key-memory reset and sometimes an app or service credential instead, after every fob has gone missing; the quote reflects which situation actually applies.
- 3
Whether the vehicle restricts the procedure
A vehicle with a manufacturer-built security gateway may need a code or an access pathway beyond a standard visit, and that requirement, where it applies, is identified and explained before it affects the quote.

Key Fob Programming: questions
How many fobs can be registered to one vehicle?
This depends on the manufacturer, since each vehicle's memory has a set limit built in, commonly enough for several drivers plus a spare. The visit checks how many the specific vehicle allows and how many are already registered, so a household adding another driver knows whether there is room before a new fob is ordered.
What happens if every fob for my car is lost at once?
On many vehicles the key memory has to be reset before any new fob can be added, since nothing already accepted remains to authorize one; some vehicles instead accept an authenticated app or manufacturer service credential without a full reset. Where a reset is needed, it may take a security code specific to your vehicle or an approved access pathway built for exactly this situation. Once the reset completes, a full new set of fobs is registered and tested before the visit ends.
Why do my fob's buttons work but the car still won't start?
This usually points to two separate systems handling two separate jobs: the remote's buttons operate the locks and alarm over radio, while a hidden chip in the fob authorizes the engine to start once it is recognized inside the vehicle. When one half is registered and the other isn't, or a chip has failed, the buttons keep working while starting authorization does not.

What the census means at the door
52%
Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.
Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.
49%
A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).
In mixed neighbourhoods, a family may move from an apartment to a house or the other way around. A locksmith who knows both kinds of door can rekey the old place for the next occupant and set up the new one on the same visit.
