Lost your only car key? What happens next (and why the dealer isn't the only option)
A mobile auto locksmith can usually cut and program a replacement where the car is parked — no tow truck, no dealer queue.
Losing the only key to a car feels like a towing problem. For most vehicles on Melbourne roads it is not — a properly equipped auto locksmith can produce and program a key at the kerbside.
What kind of key do you actually have?
A plain mechanical key is a cutting job. A transponder key has a chip that must be programmed to the immobiliser. A remote-head key adds the central locking buttons. A proximity or 'smart' key never leaves your pocket and is programmed as a credential to the car.
The further along that list you go, the more equipment and time is required — and the more the price moves.
What a locksmith needs from you
Proof of ownership, always: registration papers or a rego search matching your ID. Then the VIN, the make, model and year, and where the car is parked. Photographs of an existing key, if you still have one, speed everything up.
When the dealer is genuinely the better call
Some marques lock key generation behind manufacturer servers or require security codes that only a franchised dealer can obtain. Certain late-model European vehicles fall into this category. An honest locksmith tells you this on the phone rather than attending and failing.
Cut a spare before you need one
A spare key produced while you still have a working original is dramatically cheaper than an all-keys-lost job, because the car can be talked to using the existing credential. If you are running a single key, this is the cheapest insurance available.

FAQ
Questions people ask us about this
- Can a locksmith come to where my car is parked?
- Yes. Mobile programming at the kerbside or in a car park is the normal way these jobs are done, which avoids towing costs entirely.
- Will a new key stop the old one working?
- If all previous keys are lost, the system can usually be re-coded so old keys are deleted. Ask for this specifically — it matters after a theft or a break-up.
