- The call
- The key snapped at the head while you were turning it in a stiff, frosty door lock. Half the blade is in your hand, the rest is inside the lock, and the plastic head still lights up when you press a button.

You bought the car privately and it came with a single key on a shoelace. Every time it leaves your hand you notice, and you would like a second one made before the first goes missing.
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.

Scene 1
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.
Scene 2
A key with a cracked case, a broken ring loop or a snapped blade often keeps a perfectly good circuit board and transponder inside. The locksmith opens the old shell, lifts out the board and the chip, and seats them in a new case of the correct pattern. A fresh blade is cut to code and fitted to the new head, and a new coin cell goes in while the case is open. Because the chip and the remote circuit have not changed, no programming is required, and the rebuilt key behaves exactly as the original did on the day it left the factory.
Scene 3
On a keyless car the door cylinder can go years without a key in it, which is exactly why it seizes with salt and grit. After the visit, use the emergency blade in the driver's door once a season so the wafers keep moving, and follow the vehicle or lock maker's own maintenance instructions once the salt is off the roads in spring, since automotive locks more often need cleaning than added lubricant. In a cold snap, a small tube of lock de-icer in a coat pocket does the job; hot water only refreezes inside. A lock that has been freed during the visit stays free with this little attention.
What shapes the quoteCobourg Lock & Key Co.
FeesSame any hour
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.
Two working keys is the sensible minimum, and it is what most vehicles left the factory with. One lives on your ring; the other lives somewhere safe away from the car. With two, any future key work is an add-a-key job rather than a reset from nothing. Households that share a vehicle, or owners with a remote starter on one fob and a plain key for the valet, sometimes prefer three.
Yes, with the right paperwork. For a leased car, the lease agreement in your name together with your identification and the permit covers it. For a company vehicle, the locksmith needs authorization from the business: a work order, purchase order or letter naming the VIN and the person collecting the key. Mention the arrangement when you call so the correct document is ready and the record can be completed properly.
