Car Key Replacement in Westmount
The key snapped at the head while you were turning it in a stiff, frosty door lock.
In plain words
It helps to think of a car key as several parts sharing one case. The metal blade is the mechanical part; it opens the doors and, on older cars, turns the ignition. The transponder is a small chip with no battery that answers the immobilizer when the key is near the ignition; without the right answer the engine refuses to run. The remote is a separate radio circuit with its own battery that works the lock, unlock, trunk and panic buttons. A proximity fob adds hands-free entry and push-button start. Replacement can involve any or all of these, and a good visit begins by working out which ones you need.
How the visit goesThe engine cranks, catches for a second and dies, and a small key-shaped light keeps blinking on the dash. The blade turns the ignition and the doors perfectly well, but the car has stopped recognizing the chip inside the key.

How the visit goes
Do you still have one key that works?
The most important fact after ownership is whether a single working key exists. With one in hand, the visit is an add-a-key: the existing key proves the immobilizer is healthy, the new blade can be checked against it, and programming is usually the shorter routine. With none, it is an all-keys-lost job: the blade has to come from the lock or the code, and the immobilizer has to be reset before new keys are stored. A key that opens the doors but no longer starts the engine counts as no working key for programming purposes, though its blade is still useful as a pattern.
All keys lost: reset first, then reissue
When nothing remains, the sequence changes. The car is opened, the blade is produced from the lock or the code, and then, where the system supports it, the immobilizer memory is reset so every stored key is erased; others follow their own maker-specific route instead. New keys are then registered one after another, and registering two gives the car a spare from day one. On some vehicles this stage needs a longer security timer or manufacturer data, which is arranged in advance. The old keys, wherever they are, are now unknown to the car. Each new key is then started and driven a short distance to confirm the reset held.
Ownership paperwork kept in order
The visit closes with your documents back in your hands and a copy of the authorization record kept by the locksmith, which is the industry's way of tying every key made to a named owner and a VIN. It is a good moment to check that the vehicle permit is current and in your name, especially after a private purchase, since the ownership transfer is what makes future key service straightforward. Keep the permit in your wallet or with your licence rather than in the glovebox next to a spare key, so a break-in gives nobody both the car's identity and a way to drive it.

What affects the quote
Shell only, or a complete key
If your key's electronics are healthy, a new case and blade around the old board is a smaller job than a complete key with programming. The inspection decides which, before anything is quoted.
Erasing the keys you no longer hold
Removing lost or stolen keys from the immobilizer during the session is a small extra step, and re-registering the keys you kept follows it. If you want the old keys silenced, say so and it is quoted.
One working key or none
A spare added beside a working key is a shorter routine. Starting from nothing means working through whatever that vehicle's own all-keys-lost procedure calls for, commonly opening the car, decoding the lock and resetting the immobilizer, and the quote reflects those extra stages.
What to have ready
- Where is the car parked right now, and is it locked?
- Has the car's battery been flat or disconnected recently?
- Do you have photo identification and the vehicle permit with you?
Car Key Replacement: questions
QuestionsWhat is a transponder key, and does my car have one?
A transponder is a small chip in the head of the key with no battery of its own. When the key is in the ignition, or the fob is inside the cabin, the immobilizer sends a signal and the chip answers with a code; if the code is unknown, the engine is prevented from running. Every new light vehicle sold in Canada since September 2007 has been required to have an immobilizer, so almost any car from that time on uses one.
Can a key be made for an older car with no chip?
Yes, for a vehicle that genuinely has no immobilizer, checked by VIN and equipment rather than assumed from age, since several early-2000s vehicles already shipped with a factory immobilizer and coded key. Where that is the case, it is the simplest key work there is: a blade cut to the factory code from the VIN or to a reading of the door lock, rather than copied from a worn original. If the ignition has become sloppy, the locksmith can rebuild it in the same visit.
Will I get a written estimate before the work starts?
You should expect one. Consumer rules for motor vehicle repair work in this province call for a written estimate before any charge and for your authorization of the work, and a good locksmith works that way as a matter of course. The estimate names what is being supplied: the blank or fob, the cutting, the programming, any erasing of old keys and the number of keys, so you can see the parts of the job before agreeing.
