- The call
- After fifteen years the blade has worn to a smooth sliver. It needs a jiggle in the ignition most mornings, this week it took three tries, and a copy cut from that same worn key would only carry the wear forward.

It helps to think of a car key as several parts sharing one case. The metal blade is the mechanical part; it opens the doors and, on older cars, turns the ignition. The transponder is a small chip with no battery that answers the immobilizer when the key is near the ignition; without the right answer the engine refuses to run. The remote is a separate radio circuit with its own battery that works the lock, unlock, trunk and panic buttons. A proximity fob adds hands-free entry and push-button start. Replacement can involve any or all of these, and a good visit begins by working out which ones you need.

Scene 1
The most important fact after ownership is whether a single working key exists. With one in hand, the visit is an add-a-key: the existing key proves the immobilizer is healthy, the new blade can be checked against it, and programming is usually the shorter routine. With none, it is an all-keys-lost job: the blade has to come from the lock or the code, and the immobilizer has to be reset before new keys are stored. A key that opens the doors but no longer starts the engine counts as no working key for programming purposes, though its blade is still useful as a pattern.
Scene 2
The buttons on a key and the transponder in it are usually separate systems, and the remote is paired in its own step. Depending on the vehicle, that is an on-board routine of ignition cycles and button presses, or a command sent through the programming tool. A proximity fob is registered so the car detects it near the door handles and inside the cabin, and push-button start is tested with the fob in a pocket, then held against the start button as the backup method. Remote start, trunk release and panic are checked one at a time, since a wrong part number can pass every step except the one you use most.
Scene 3
A blade cut to code is made to the lock's original dimensions, so it should turn smoothly from the first use. What it should never do is need the wiggle the old key needed; if it does, or it feels stiff or forced, that points to worn ignition wafers or a cutting issue, and the cylinder is checked and serviced or rebuilt rather than waited out. Keep the new key on a light ring, since a heavy bunch hanging from the ignition is what wears the wafers in the first place.

Often, yes, for vehicles with a supported conventional key system: the car is opened, a blade is produced by decoding the door lock or retrieving the factory key code, and the immobilizer is reset so the missing keys are erased before new ones are stored. A key-card or phone-key vehicle, or one needing a dealer procedure, follows its own route instead, which is why the VIN is asked for on the first call.
Adding a key leaves the existing keys in place; the car simply learns one more. The exception is a deliberate all-keys-lost reset or an erase you ask for, which clears every stored key and then registers only the ones you present. For that reason the locksmith asks you to bring every key you own to the visit, so each one can be re-registered and tested rather than left behind and forgotten by the car.
It depends on the starting point. Adding a spare to a car with a working key is often the shortest kind of visit. An all-keys-lost job on a newer vehicle takes longer, because the car has to be opened, the lock decoded, the immobilizer reset and any security timer waited out. Milling a high-security blade and pairing a proximity fob add their own steps. The locksmith gives you a realistic window once the VIN and the situation are known.
