- 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.
The 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.
In plain words
Winter produces its own kind of key trouble. Coin cells lose output in deep cold, so a fob that was fine in October goes quiet in January; a fob dropped in slush or lost under a snowbank is gone until spring; and the mechanical door lock on a keyless car, untouched for years and crusted with road salt, is stiff exactly when you need it. A replacement visit in these conditions covers it all: a working fob, fresh batteries, a cut emergency blade, and a door cylinder cleaned and lubricated per the maker's instructions, so the metal key is a real backup rather than a decoration.

How the visit goes
Scene 1
Proof that the car is yours to key
Before a blank leaves the van, the locksmith confirms that the person asking for a key is entitled to one. Government photo identification is the first piece. The second is a document tying that person to this vehicle: the vehicle permit with the VIN on it, an insurance slip, a lease, or fleet paperwork for a company car. The VIN on the paper is compared with the one stamped on the dash and printed on the door label. A car bought last week and still in the seller's name, an estate vehicle or a family member's car each has its own paper trail, and mentioning it on the phone means the right document is at hand.
Scene 2
Milling a high-security blade
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
Looking after the mechanical lock you rarely use
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 quoteErindale Lock Experts
- Extracting a broken key
- Drawing a snapped blade out of a door or ignition cylinder without harm to the lock is a separate piece of work, done before the new key is cut, and it appears on the quote as its own line.
- 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.
- Edge-cut or high-security blade
- A plain edge-cut blade is cut on a code machine in moments. An internal high-security blade is milled to fine tolerances on a different machine, and the blanks themselves are dearer, so the blade type shows up in the quote.

Let's clear a few things up
Can you make a key if every key to the car is gone?
Often, yes, for vehicles with a supported conventional key system: the car is opened, a blade is produced by decoding the door lock or retrieving the factory key code, and the immobilizer is reset so the missing keys are erased before new ones are stored. A key-card or phone-key vehicle, or one needing a dealer procedure, follows its own route instead, which is why the VIN is asked for on the first call.
What is the difference between adding a spare and replacing all keys?
Adding a spare uses an existing working key as the reference: the new blade is cut and checked against it, and the immobilizer is asked to accept one more key alongside the old. Replacing all keys starts with nothing: the lock is decoded for a blade, and the immobilizer is reset to forget every previous key before new ones are stored. The second job is longer and sometimes needs manufacturer data, one more reason to keep a spare.
What 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.

2021 census: what it means at the door
Every square is one home in a hundred.
- 38 in 100 homes · mixed ages
- 37 in 100 homes · mostly attached
- About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.A mix of eras means a mix of bores and backsets. Standard modern sizes on one door, older dimensions on the door across the street. Carrying adapter plates and cylinders in both ranges lets a locksmith fit upgrades cleanly to either.
- Single-detached houses make up about 37% of homes in Mississauga (2021 Census).In a building, a lockout happens in a hallway rather than a porch, and the neighbours notice. A locksmith confirms you belong to the suite, opens the door with the least fuss the lock allows, and leaves the door and cylinder intact for the night.
