Spare Car Key Duplication in Cedarvale
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.
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 goesA teenager just passed a driving test and reasonably wants a key of their own rather than negotiating over the family's single copy every time the car is needed. Two drivers and one key keep colliding on the same schedule.

How the visit goes
Locating the right blank
A correct spare starts with the correct blank: the same blade profile as the original, and where relevant the same shell shape for a remote head or proximity fob so the buttons and battery compartment line up. Aftermarket blanks exist for most common platforms, while a less common or very recent model sometimes calls for a shell sourced specifically for that vehicle. Getting this step right avoids a mismatch discovered only after cutting has begun, and it is one of the reasons the vehicle's year, make and model are confirmed early rather than assumed from the look of the current key.
Testing every key before the visit ends
Once cutting and programming are finished, each key is tested independently: every door lock, the trunk or hatch, the ignition or the start button, and any remote functions, with the other key set aside so neither test is quietly helped along by a second signal nearby. The vehicle is started and shut off more than once to rule out an intermittent fault, and remote buttons are pressed from a normal distance rather than pressed against the car. Only once both keys pass on their own is the appointment considered complete, rather than treating a single successful start as proof enough.
A record worth keeping
A short note of how many keys exist for the vehicle, what each one can do, and who holds it is a small thing to write down and a genuinely useful one to have later, whether that later is a private sale, an insurance question, or simply working out which key someone borrowed and forgot to return. This record also makes any future visit faster to start, since a returning locksmith or a different one entirely can begin from a known baseline instead of counting keys from scratch.

What affects the quote
Which key system the vehicle uses
A plain mechanical blade, a transponder key, a remote-head key and a proximity fob each call for different tools and different amounts of time, so identifying the system early shapes the whole quote before any cutting or programming starts.
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.
Reprogramming to drop a missing key
When a key is genuinely unaccounted for, having the vehicle's system stop recognizing it is separate work from cutting a new spare, and is scoped as its own step when it is needed.
What to have ready
- Is the vehicle registered to you, or to someone else?
- Do you want the spare to match every function, or just start the car?
- How many spare keys would you like made?
Spare Car Key Duplication: questions
QuestionsWhat 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.
What testing happens before I leave with the new key?
Every door lock, the trunk or hatch, the ignition or start button, and any remote functions are checked with the new key on its own, apart from the original, so neither key is quietly helped along by the other's signal. The vehicle is started more than once to rule out an intermittent issue, and only once both keys pass independently is the visit considered finished.
Can a spare be made from a key that is already worn?
Yes, and it is often a good reason to make one. Rather than tracing every rounded edge of a worn blade onto the new copy, the locksmith can decode the lock or cut to a valid factory code for the blade, then read or clone the chip data separately for the electronics, producing a spare that is cleaner than the original rather than a copy of its wear. The worn key can then be compared against the fresh one and retired if it is due for that.
