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.
Car key replacement means producing a key that works your specific vehicle when the original is lost, broken, stolen or no longer recognized. On many modern cars that is more than cutting metal: the blade fits the locks, a transponder is taught to the immobilizer before the engine will run, and any remote or proximity function is paired separately; some current vehicles instead use a phone key or key card with no cut blade at all. An automotive locksmith confirms your entitlement, identifies the exact key system from the VIN, cuts the blade to code, programs the electronics and tests every function before handing it over.

Scene 1
A damaged key is examined before anything is ordered, because its parts may be reusable. A cracked shell often still holds a healthy circuit board and transponder; those can move into a new case with a freshly cut blade, and no programming is needed. A snapped blade with an intact head keeps its chip and remote. A key that went through the wash may have lost the remote but kept the chip, since the transponder has no battery of its own. Sorting this out with a battery test and a chip reader decides whether you need a shell, a blade, a remote, or a complete new key.
Scene 2
Many vehicles from the last two decades use an internal-cut key, sometimes called a laser-cut or sidewinder key, with a wavy groove milled into the flat of the blade instead of teeth along its edge. These are produced on a milling cutter that follows the code to a fine tolerance, because the wafers in a high-security lock have little forgiveness for an off-depth cut. The blank is clamped, the groove is milled on both sides, the burrs are cleaned off and the blade is checked in the lock for smooth travel. A blade that drags or catches is recut rather than forced.
Scene 3
If a key was lost or stolen and you chose to have it erased, the car no longer answers to its chip. Whoever finds it holds a blade that may open a door and a fob that can no longer start the engine or, once unpaired, work the locks. The locksmith tells you how many keys the vehicle now recognizes, which should equal the number in your hand. If a stranger holding a working blade still bothers you, the door and ignition locks can be swapped to a new cut, and that is a separate decision you can take with a clear head rather than on the day.

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.
