Spare Car Key Duplication in Lundy's Lane
The blade on the everyday key has gone shiny and thin along one edge, and lately it needs a wiggle before the ignition catches. Nobody wants to be holding a failing original with nothing waiting in reserve if it finally gives out.
Spare Car Key Duplication
In plain words
Making a spare before the original goes missing is simpler than making one after, because the whole process is built from a working key to read or trace from. With the vehicle and its existing key both present, the locksmith identifies the blade profile and the chip or coding the immobilizer expects, produces a matching blank, and gives it the same electronic identity as the first key. Testing both keys side by side in every door and the ignition confirms the spare performs the same way, so a future lost key becomes an errand rather than a call for entry.
How the visit goesThe 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.

How the visit goes
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.
Bringing a second vehicle onto the same key
Households running two vehicles from the same manufacturer sometimes want one key that opens and starts both, which needs more than a shared keyway: the two locks must also take a compatible bitting, or one vehicle's cylinders need rekeying to match, and the transponder chosen has to be capable of authorization on both immobilizers. The locksmith reads both vehicles' requirements before cutting anything, and where a single key genuinely will not satisfy both locks and both immobilizers, the answer is two separate keys carried on one ring, explained before any cutting starts so expectations match what the hardware can actually deliver.
Where the spare should live
A spare that stays inside the vehicle solves little if the vehicle itself is what gets locked or lost, so the sensible places are a bag that travels separately, a drawer at home, or with a family member who is easy to reach. A passive proximity spare benefits from a signal-blocking pouch when it is stored, since that kind of fob keeps broadcasting even while it sits untouched in a drawer; a standard button-operated remote works differently and does not need the same pouch. Wherever it ends up, the location is worth sharing with at least one other person in the household so the spare is findable by someone other than the person who put it away.

What affects the quote
Same fees day, night or weekend
1Choosing a limited-function spare
A simplified key built for a valet or a specific driver, without every remote feature the primary key carries, generally involves less programming than matching every function exactly.
2Whether 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.
3Fob 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.
Spare Car Key Duplication: questions
Can a spare be made if the vehicle has an aftermarket alarm or remote starter installed?
Generally yes, though it is worth mentioning any aftermarket system when you call, since a factory immobilizer that has been wired into a third-party alarm or remote starter sometimes behaves differently from the standard setup the locksmith expects. Knowing this in advance lets the visit account for it rather than discovering it partway through programming.
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.
What is a relay attack, and does it matter for my spare?
A relay attack is when nearby equipment picks up a proximity fob's signal from inside a house and relays it to a vehicle parked outside, tricking the car into thinking the key is close enough to unlock or start. It matters for every fob in the household, spare included, which is why storing any proximity key in a signal-blocking pouch when it is not being carried is worth doing for all of them.
