Car Key Replacement in Woodstock
The fob went through the washing machine in a jacket pocket. It came out clean and completely silent.
Car Key Replacement
In plain words
Losing a key is also a security event, and replacement is the moment to close it. The locksmith can erase the missing key from the immobilizer's memory during programming, so a stranger who finds it holds a blade that opens a door and a chip the car no longer answers to; the remote is unpaired the same way. If you would like to go further, every cylinder the old blade operated, doors, ignition and any trunk or fuel-door lock, can be changed so it fits nothing. You leave with new keys that work, old keys that are silent, and a note of how many keys the car now recognizes.
How the visit goesThe fob went through the washing machine in a jacket pocket. It came out clean and completely silent. Nothing unlocks, the push-button start ignores it, and the little metal blade hidden inside only opens the driver's door.

How the visit goes
Reading the VIN for the key system
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.
Testing every function before the handover
The visit ends with a checklist rather than a handshake. The blade is tried in the driver's door, the passenger door and the trunk lock, and in the ignition where one exists. The engine is started, allowed to run, shut off and started again. Each button is pressed and watched: lock, unlock, trunk, panic, remote start. On a proximity car, the handles are approached with the fob in a pocket and the start button is tried the same way. The spare goes through the identical routine. Anything that stays silent is sorted out on the spot, and the tally of keys the car recognizes is written down for you.
A record of what your key actually is
A car key has an identity of its own: a blade profile, a transponder type, a remote frequency and a part number, and sometimes a key code printed on a tag. The locksmith notes these for you, along with the count of keys stored in the car, so the next spare can be prepared from the details rather than from scratch. Keep the note with your insurance papers rather than in the car. If the vehicle ever changes hands, the record also lets the new owner have the old keys erased and fresh ones made without guesswork about what the car uses.

What affects the quote
Same fees day, night or weekend
1Original or aftermarket part
A manufacturer fob and a good aftermarket equivalent both do the job on many models, at different part costs. The locksmith says which is proposed for your car and why, and the quote names the part.
2Security data for the vehicle
Some cars give up their programming PIN through the tool; others require the code to be retrieved from manufacturer secure data, which involves a registered request. That step is quoted when the VIN shows it applies.
3Functions on the fob
Locking and unlocking come with every fob. Trunk release, panic, remote start and power liftgate depend on the fob part number, so a fob with more functions is quoted differently from a basic one. Phone-as-a-key is quoted separately, set up through the vehicle's own software rather than by fob choice.
Car Key Replacement: questions
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.
The fob died in the cold. Is that a battery or the key?
Almost always the battery. Coin cells deliver less in deep cold, and a cell that was already weak goes quiet on the first bitter morning. Most cars still start with a flat fob if it is pressed to the start button or laid in a marked slot, and the emergency blade opens the door. Replace the cell, and if the fob stays silent with a fresh one, the remote board or a corroded contact is the next thing to look at.
Can you make a key for a car with push-button start?
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.
