Automotive locksmith making a replacement for a lost car key in Melbourne

Replacement car keys, cut and programmed on site

A car key replacement means cutting and, where needed, programming a new key for your vehicle when the original is lost, damaged or stolen. Our mobile locksmiths make replacement keys for many makes and models on site, including transponder, smart and remote keys, then test the new key before we hand it over.

What car key replacement covers

Most drivers call us for a replacement key after losing their only key, snapping a worn key, or wanting a spare before something goes wrong. Common warning signs include a key that sticks in the barrel, buttons that no longer lock the car, or a blade that has visibly bent or cracked.

To prepare a new key we usually need the make, model and year of your vehicle, the type of key you have, and proof that you own or are authorised to use the car. With those details our locksmith can cut a new blade, match the key code, and program a transponder or smart key so the vehicle recognises it. If you still have one working key we can usually add another. If every key is lost, we assess the vehicle first and explain your options before any work begins.

Types of car keys we replace

Lost car keys

Lost your only key? We can generate and program a replacement from your vehicle details and proof of ownership, so you avoid a tow to the dealer.

Spare car keys

Having a spare cut and programmed before you lose a key is the cheapest way to avoid a lockout. We can make a backup while you have a working key.

Damaged and worn keys

Bent, cracked or worn blades can jam in the ignition or door. We cut a fresh key to the correct code and transfer any chip so it works reliably again.

Transponder keys

Most modern keys carry a transponder chip that talks to the immobiliser. We supply and program the correct chip so the engine will start.

Smart and proximity keys

Keyless-entry and push-button-start cars use a proximity smart key. We can replace and pair a smart key for many models when your vehicle allows it.

Remote and flip keys

Remote fobs and fold-out flip keys combine central locking with the blade. We replace the housing, blade and chip, then sync the remote to your car.

How our car key replacement works

Understanding your car key type

A basic key blade is cut to a key code and turns the lock mechanically. A transponder key adds a chip that must be recognised by the immobiliser before the car will start. A remote key or remote fob also controls central locking, while a flip key folds the blade into the fob. A smart key or proximity key lets you unlock and start the car without taking the key out of your pocket. Where the original is gone, the VIN and key code help us produce a correct replacement and match it to your vehicle.

Vehicle makes we make keys for

We cut and program keys for many popular makes on Melbourne roads, including Toyota, Mazda, Ford, Holden, Hyundai, Kia, Nissan, Mitsubishi, Subaru, Honda and Volkswagen, along with a range of European models.
