- The call
- The proximity fob has ridden in a pocket for years, the range feels shorter than it used to, and a dashboard warning mentioned a battery a while back. Nobody has sorted out what happens on the day it finally goes dark.
One key opens the car, starts the car, and rides in one pocket every day. Nothing backs it up.
In plain words
Spare car key duplication puts a second working key into your hand while the first is still around to copy from. The locksmith checks that you are entitled to the vehicle, reads the blade the existing key was cut to, and gives the new blank the same electronic identity the original carries, whether that means cloning a compatible transponder chip or enrolling a fresh chip through the car's diagnostic port. Before the visit ends, the new key is proven in every door, the trunk and the ignition or start button, so you leave with two keys known to work, not one tested key and one hopeful copy.

How the visit goes
Scene 1
Looking at the working key itself
The existing key is examined for exactly what it is: a plain blade, a blade carrying a transponder chip, a remote head with buttons built into the plastic, or a proximity fob meant to stay in a pocket. Wear matters too; a blade that has thinned unevenly or a button that sticks tells the locksmith what to expect when it is time to trace or copy from it, and whether the original itself might be due for retirement once the spare exists. A key that has already been altered, filed or repaired is noted before it becomes the reference for a new copy.
Scene 2
Matching a remote head or fob
When the original carries buttons for locking, unlocking or remote start, the new key or fob is programmed to the vehicle's receiver so those same functions respond from the spare. This usually means putting the vehicle into a programming sequence from inside the cabin, then pressing the new remote's buttons in the order the manufacturer specifies. Some platforms allow this through the doors and ignition alone; others need the diagnostic port involved as well, particularly when the remote functions are tied into the same module that manages the immobilizer, so the two steps happen together rather than separately.
Scene 3
Two keys, both proven
The visit ends with two keys that have each been tested on their own: every door, the trunk or hatch, the ignition or start button, and any remote functions. Neither key is a backup that has only been assumed to work, and neither is treated as the senior copy. It is worth deciding on the spot which key rides on the daily ring and which goes into storage, and writing that decision down somewhere the household will actually check later, such as a shared note or a label on the ring itself, rather than trusting memory a year from now.

What shapes the quoteJarvis Lock & Key Specialists
- Scheduling more than one vehicle together
- Two vehicles booked into the same visit, such as a household's pair of cars, are generally more efficient to handle together than arranging two separate appointments on different days.
- Getting to the vehicle
- Straightforward access, such as a driveway or an open lot, is simpler than a locked underground garage, a gated lot or a vehicle parked somewhere with restricted entry, which the quote accounts for.
- Aftermarket alarms or remote starters
- A factory system wired into a third-party alarm or remote starter can add extra steps to programming, since the added equipment sometimes changes how the vehicle's module responds during enrolment.

Asked and answered
What identification do I need to bring for a vehicle that isn't mine, like a company car?
Bring whatever document shows your connection to the vehicle in that situation: a company letter or fleet record for a workplace vehicle, a lease agreement for a rented one, or a note from the registered owner for a family member's car. The locksmith is confirming that the person asking for a key is entitled to hold one, which protects the vehicle's owner as much as it protects you.
How should I store the spare once I have it?
Somewhere other than inside the vehicle, since a spare kept in the glovebox solves little if it is the vehicle itself that becomes inaccessible. A bag that travels separately, a drawer at home, or a trusted family member all work. A passive proximity spare also benefits from a signal-blocking pouch during storage, since that kind of fob keeps broadcasting even sitting untouched in a drawer; a standard button-operated remote does not need the same pouch.
How is a proximity or smart key different to duplicate compared to a regular key?
A proximity key usually has no blade to trace, so the process is almost entirely electronic: pairing a new fob to the vehicle's receiver and enrolling it through the diagnostic connection so the car recognizes it as an additional key. Many still hide a small mechanical blade inside the shell for emergencies, and that blade is cut separately to match the door lock, even though it is rarely used day to day.
Car Keys
- Car Key ReplacementAfter fifteen years the blade has worn to a smooth sliver.
- Key Fob ProgrammingThe remote clicks the way it always has, but the vehicle no longer locks, unlocks or answers with its usual chirp.
- Transponder Key ProgrammingThe blade snapped off flush with the door lock last winter, and the shop that cut a replacement only matched the metal shape.
- Ignition Lock RepairThe key turned the engine off in the driveway and now refuses to come back out.
- Vehicle Lock RepairPressing the remote locks three doors with a solid clunk and leaves the rear passenger door untouched, every single time.

2021 census: what it means at the door
Every square is one home in a hundred.
- 57 in 100 homes · older homes
- 84 in 100 homes · mostly houses
- About 57% of homes in Haldimand County were built in 1980 or earlier, according to the 2021 Census.Older homes tend to have had many hands on their doors: owners, tenants, tradespeople, family. A locksmith visiting such a house pays attention to who holds keys now, and rekeying or a keyed-alike set often matters more than any new hardware.
- Single-detached houses make up about 84% of homes in Haldimand County (2021 Census).Detached homes are exposed to weather on every side, so exterior locks see rain, salt and freezing air directly. Choosing hardware with a good finish and a cylinder that tolerates cold, then lubricating it properly, keeps every door turning through winter.
