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.

Sound familiar?

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.

  1. 1

    Which functions the new key should have

    Not every key for the same car does the same things, so the locksmith asks what the old one did and what you would like now. Lock and unlock are standard; trunk release, panic alarm, remote start and memory seat recall depend on the fob part number and how the car is equipped. Phone-as-a-key is separate, set up through the vehicle's own software and account rather than by fob part number. Some owners want a plain spare key; others want a full duplicate of the original fob. Naming the functions up front means the right part is fitted and each one is tested at the end.

  2. 2

    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.

  3. 3

    A crisp new blade in a well-used ignition

    A blade cut to code is made to the lock's original dimensions, so it should turn smoothly from the first use. What it should never do is need the wiggle the old key needed; if it does, or it feels stiff or forced, that points to worn ignition wafers or a cutting issue, and the cylinder is checked and serviced or rebuilt rather than waited out. Keep the new key on a light ring, since a heavy bunch hanging from the ignition is what wears the wafers in the first place.

What affects the quote

  1. 1

    Shell only, or a complete key

    If your key's electronics are healthy, a new case and blade around the old board is a smaller job than a complete key with programming. The inspection decides which, before anything is quoted.

  2. 2

    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.

  3. 3

    Functions 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.

Advice · (226) 777-6122

Does programming a new key affect the keys I already have?

Adding a key leaves the existing keys in place; the car simply learns one more. The exception is a deliberate all-keys-lost reset or an erase you ask for, which clears every stored key and then registers only the ones you present. For that reason the locksmith asks you to bring every key you own to the visit, so each one can be re-registered and tested rather than left behind and forgotten by the car.

My fob is cracked but still works. Do I need a whole new key?

Usually not. A cracked case often protects a healthy circuit board and transponder, and those can be moved into a new shell of the same pattern with a freshly cut blade. Because the electronics are unchanged, nothing needs programming, and the rebuilt key behaves exactly as before. A new key is the answer when the board is corroded, a button has died or the chip has been damaged.

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.

What the census means at the door

52%

Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.

Decades of seasons move a frame, and an older house often has a front door that locks easily in summer and fights in winter. Setting the strike with the seasons in mind, and choosing a lubricant that stays fluid in the cold, keeps it working year round.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).

Where housing types are mixed, the same lost-key call means different things. In a house, rekey every door on the property. In an apartment, rekey the suite door and check with management about the common entrance. The locksmith asks which it is first.
