The car came with a single key when the sale went through, and that key is the only thing standing between the household and being stranded. A second one has been on the list for weeks, quietly moved down every time something more urgent came up.
There are really two separate keys hiding inside one piece of metal and plastic: the cut, which is entirely mechanical and opens doors and turns cylinders, and the code, which is electronic and tells the immobilizer to allow the engine to run. A key can be perfectly cut and still leave a car cranking without starting if the code was never written. Programming is the part of the job that handles the code, using equipment built to read and write the exact system fitted to that vehicle.

Scene 1
Some vehicles let a locksmith see and edit the key list directly once a diagnostic tool is connected to the onboard port. Others hide that list behind a manufacturer security session that has to be established first, particularly on newer models with more layers between the port and the immobilizer itself. Knowing which situation applies before starting sets the right expectation for how the visit will unfold, and for all-keys-lost work it decides whether the first step is reached directly or has to be built from nothing.
Scene 2
The mechanical side of the job comes first and is the more familiar half of it: the blade is cut to the lock's own pattern, either from a code on file or by duplicating a working key, and fitted into a blank carrying the correct chip. A perfectly cut blade still will not start a vehicle with an immobilizer on its own, which is the detail that catches out a counter kiosk. The two halves of the key are treated as separate tasks throughout, cut first, chip second.
Scene 3
A fob that survived one winter will not necessarily survive the next one on the same battery, since cold weather is genuinely harder on a battery that was already getting weak. Testing it before the temperature drops, rather than after it has already failed on a frozen morning, catches a fading battery while replacing it is still a small errand rather than an unplanned one. The metal blade inside a proximity fob does not mind the cold at all, which is exactly why it is worth knowing where it is.
What shapes the quoteLawrence Heights Locksmith Services
FeesSame any hour
That pattern, the starter turning the engine over without it catching, often points to the key or immobilizer rather than a fuel or ignition-timing fault. A flashing security light on the dashboard while this happens adds to that picture. A diagnosis, checking whether the vehicle actually recognizes the key's chip, is what confirms which one it is before any programming begins.
It can, mainly because a remote starter is often wired into the same ignition and immobilizer circuits a new key needs to talk to. The locksmith asks about any aftermarket installation before starting, and if it is involved, checks how it was wired in rather than assuming the factory system is untouched underneath it.
Nothing changes about it. A spare is added alongside the existing key without clearing or altering anything already stored in the vehicle's memory. The only keys that get cleared are the ones you specifically identify as lost, stolen, or no longer wanted, and that is confirmed with you before any clearing happens.
