- The call
- The only key to the car went into the lake with the kayak. Now the car sits locked in the driveway with a full tank, and there is no spare in the house, in a coat pocket or anywhere else.

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.
Older vehicles without an immobilizer are a pleasure to key, but whether a given car has one is checked rather than assumed from age, since several early-2000s vehicles already shipped with a factory immobilizer. Where a car genuinely needs only a blade, it is cut to the factory code or to a reading of the lock rather than copied from a worn original, so it seats cleanly in an ignition that has seen twenty winters. Where the ignition wafers are tired, the locksmith can say so and service the cylinder in the same visit. The result is a key that turns like the car was new, without the daily jiggle.

Scene 1
The seventeen-character VIN tells the locksmith what kind of key the car was built with. From it, together with the year, make and model, comes the blade profile (a plain edge cut or an internal high-security cut), the transponder type and immobilizer generation, the remote's frequency and part number, and whether the car uses a proximity fob, or instead a phone-key or key-card system with no cut blade at all. This lookup happens before the visit so the correct blank, shell or fob is in the van, and it flags systems needing a security PIN, manufacturer data or a dealer procedure. A photo of the old key, if any survives, confirms the reading.
Scene 2
With the blade cut, the electronic half of the job begins. On a vehicle with OBD-programmable keys, the locksmith connects a programming tool to the diagnostic port under the dash, selects the exact vehicle and immobilizer system, and starts a session that introduces the new transponder to the car. Some systems accept the key in moments; others enforce a security wait timer, or ask for a PIN that the tool reads from the vehicle or that is obtained through the manufacturer's secure-data route. The key is cycled in the ignition or held to the start button when prompted, and the tool confirms the number of keys the car now recognizes.
Scene 3
A replacement fob leaves with a fresh coin cell, and a small habit keeps it that way. Most vehicles show a low-battery message on the dash weeks before the fob goes quiet; treat it as a to-do rather than an alarm. Cold reduces what a coin cell can deliver, so a battery that is fine in autumn can fail on a January morning. The locksmith shows you how the car starts when a fob is flat, usually by holding it against the start button or in a marked pocket, and where the emergency blade is released, so a dead battery is an errand rather than a stranding.

FeesSame any hour
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.
A few. Some manufacturers lock key programming behind data or tooling that only their dealer network can run, particularly on the newest models and on certain all-keys-lost situations. The locksmith checks your VIN against what the equipment supports before the visit and tells you plainly if the dealer route applies. Even then, the locksmith can often cut the emergency blade, open the car and handle the mechanical side so the dealer step is a small one.
On many vehicles, yes: a proximity fob is registered to the vehicle through the diagnostic port in much the same way as a transponder key, and then tested for passive entry at the handles and for starting with the fob in a pocket. Other systems pair a proximity fob through onboard, app-based or dealer-only steps instead. The emergency blade tucked inside the fob is cut to the door lock so you have a mechanical way in, and the VIN check reveals in advance which route a given vehicle needs.
