- The call
- A car sits at the cottage all season, and the only key to it lives on a ring three hours away in the city. Every visit begins with the same small worry about whether that ring made it into the right bag.
The paperwork for the used car changed hands last week, and the previous owner mentioned, almost as an afterthought, that a second key never turned up. One worn blade on a single ring is now the entire access system for the vehicle.
In plain words
Driving on a single key means a lost pocket, a dropped bag or a worn blade can turn into a day without a car. A spare closes that gap while the original is still on hand to work from, which is the easiest moment to make one, since the vehicle, the lock system and a proven key are all present together. The locksmith matches the new blank to the blade profile, gives it the chip or code the immobilizer expects, and tests it apart from the original in every door and the ignition before calling the job finished.

How the visit goes
Scene 1
Reading the vehicle's key system
Every make, model and model year settles on a particular combination of blade shape and electronic layer, and the locksmith identifies both before ordering a blank. The VIN narrows the search to the exact immobilizer generation the factory installed, which decides whether the chip can be copied directly or needs to be freshly coded through the car's diagnostic connection. A vehicle that has already had an aftermarket alarm or remote starter fitted sometimes changes what the factory system expects, so a look under the dash or a question about prior work can matter as much as the VIN itself.
Scene 2
Cutting the blade
A mechanical duplicate is produced either by tracing the original on a key-cutting machine, which follows every notch of the existing blade into a fresh blank, or by cutting to a factory code pulled from the VIN and the lock manufacturer's records. Code-cutting is used when the original is too worn to trace reliably, since copying a worn blade would simply pass its rounded edges on to the spare. Either way the new blade is deburred and test-fitted into the door or ignition lock before any electronic work begins, so a mechanical problem is caught early rather than blamed on the chip later.
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 quoteBuchanan Lock Services
- Whether remote functions are included
- A spare limited to the blade and chip that unlock and start the vehicle involves less programming than a full match of every remote button the original carries, and the quote follows whichever is chosen.
- Fob battery and physical condition
- A fob that needs a fresh battery or shows cracking or water exposure adds a small amount of extra work beyond programming a key that is otherwise in good shape.
- Sourcing the blank or shell
- Common platforms use blanks kept in regular stock, while a less common model or an unusual shell sometimes has to be sourced specifically for that vehicle before work can begin.

What to expect, 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.
Is it possible to leave out certain functions on the spare, like remote start?
Yes. A spare can be built to do everything the first key does, or scaled back to just the blade and chip that unlock a door and start the engine, without a remote start button or a trunk release. This is agreed before programming begins and is a deliberate choice rather than a lesser copy, useful for a valet, a young driver, or anyone the household wants kept to essential access.
Does cold weather affect a key fob?
Yes, in a couple of small ways. Battery performance drops in cold temperatures, so a fob that already had a fading battery is more likely to act up on a cold morning, and a proximity system's range can feel shorter in the cold as well. Testing a spare's battery before winter, and keeping a spare battery on hand, avoids being caught out by either.
Car Keys
- Car Key ReplacementAfter fifteen years the blade has worn to a smooth sliver.
- Key Fob ProgrammingA new driver has joined the household, and the one existing fob is the only key anyone has ever had cut for this vehicle.
- Transponder Key ProgrammingSince the remote starter was installed last month, the original key has started acting strangely, the car catches on the first…
- Ignition Lock RepairThe key slides in fine and turns without any resistance at all, and the dash lights flicker, but nothing catches.
- Vehicle Lock RepairThe car came with a second key that grinds and catches in the rear door, unlike the smooth key you use every day on the front two.

2021 census: what it means at the door
Every square is one home in a hundred.
- 61 in 100 homes · older homes
- 56 in 100 homes · mixed housing
- About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Where most homes were built decades ago, doors often still carry their original mortise locks and brass knobs. That hardware can usually be cleaned, re-sprung and kept in service, with a modern deadbolt added above it for strength without losing the look.
- Single-detached houses make up about 56% of homes in Hamilton (2021 Census).Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
