Cut, programmed and tested at your car. Most models, most years.

Standard cut metal key with a transponder chip inside the head. Nissan-family NATS immobilizer verifies the chip before the ECU allows starting. Duplicating one usually means cutting a blank plus programming the transponder ID into the vehicle.
Push-button start with a proximity fob the car detects by radio signal — no key blade turned in the ignition, though most fobs hide a small mechanical emergency blade for the door. Programming touches both the BCM and NATS-linked immobilizer system.
Housed inside proximity fobs for manual door entry if the fob battery dies. It does not start the car by itself and typically is not separately transponder-coded.
A plain metal blade, a transponder chip, a remote and a proximity fob are four different jobs.
Newer immobilizer generations take extra steps — and on the newest systems, extra authorization.
Copying a working key is the small version of the job; starting from zero keys is the big one.
Secure garages, gated lots and after-midnight calls can change the trip, never the honesty of the quote.

Infiniti shares Nissan's NATS (Nissan Anti-Theft System) immobilizer architecture across the lineup. On proximity-key models this pairs with BCM-based programming, meaning a new key or fob generally has to be matched to both the immobilizer and the body control module before the car will start. Procedures and required tool access vary by model year and platform, so it's worth asking a locksmith upfront whether a given Infiniti model is one they've programmed before.
An all-keys-lost situation on most Infiniti models is solvable by a properly equipped mobile locksmith, but it's more involved than a routine duplicate — pricing, timing, and required documentation (proof of ownership, registration matching the VIN) should be confirmed directly with whoever is dispatched. Some newer or higher-security configurations may need dealer-level access or a longer lead time; a locksmith should say so upfront rather than promise a fixed turnaround.
Often yes, for models within a locksmith's tool and software coverage, but it takes longer than a duplicate and needs ownership proof. Some model years or higher-security setups may point toward a dealer instead — worth asking directly before scheduling.
On models with the Intelligent Key proximity system, yes — the fob has to be matched to both the NATS immobilizer and the BCM, not just cut. Older turnkey models only need the transponder chip programmed.
It depends on the model year, platform, and whether it's a duplicate or an all-keys-lost job. A locksmith should give a realistic estimate on the call rather than a fixed number of minutes.
Sometimes it's a dead or low fob battery, sometimes a programming or antenna issue. A locksmith can usually diagnose which on-site.
Aftermarket transponder keys and fobs exist and are generally cheaper, but fit and long-term reliability can vary by supplier — ask what's being installed before agreeing to the job.
No — it's for manual door entry only if the fob battery dies. Starting the engine still requires the proximity fob itself (or, on some models, holding the fob near a designated spot).
