Before requesting a quote

Quotes and bookings

Supplying the exact vehicle details at the start is the best way to avoid an incorrect key identification or an unrealistic price estimate.

What details should I send for a car-key quote?

Send the vehicle make, model and year, the suburb or exact vehicle location, whether any working key remains, what service is required, and clear photos of the existing key, ignition or start button and dashboard where possible.

Why can car-key prices vary so much between vehicles?

The price depends on the vehicle security system, key type, whether all keys are lost, parts availability, required programming access, location and appointment timing. Two vehicles that look similar can use completely different key systems.

Does sending a message confirm an appointment?

No. An appointment is confirmed only after the job details, price, location and attendance time have been agreed. A booking requirement may apply before travel is reserved.

Understanding modern keys

Keys, immobilisers and programming

A key can contain separate mechanical, remote-control and immobiliser functions. A fault in one part does not always mean every function has failed.

What is a vehicle immobiliser?

An immobiliser is an electronic anti-theft system that checks whether an authorised key or smart key is present before allowing the engine to start. The exact design varies between vehicle makes, models and years.

What is a transponder car key?

A transponder key contains a small electronic chip that communicates with the vehicle immobiliser. The metal blade may turn the ignition, but the engine normally will not start unless the vehicle recognises the programmed transponder.

What is a smart or proximity key?

A smart or proximity key allows supported vehicles to detect the key nearby, commonly enabling push-button starting and passive locking or unlocking. It still contains vehicle-specific electronic security information and must be correctly matched and programmed.

Is the remote-control part of a key the same as the immobiliser chip?

Not always. The remote buttons operate locking functions, while the transponder or proximity system authorises starting. One function can fail while the other still works, depending on the key and vehicle.

Can an unprogrammed key start my car?

Usually not. It may mechanically turn the ignition or unlock a door, but the immobiliser normally prevents the engine from starting. Vehicle behaviour varies, so repeatedly trying an incorrect or damaged key is not recommended.

Can you make a spare car key while I still have one working key?

Yes, for many supported vehicles. Making a spare while a working key remains is usually simpler and less expensive than replacing every key after they are lost.

When the vehicle cannot be used

Lost keys, spare keys and lockouts

All-keys-lost work usually requires more steps than making a spare from a working key. Vehicle access and lawful authority also need to be established.

What can be done when all car keys are lost?

For many supported vehicles, a new key can be originated and programmed at the vehicle. The exact procedure depends on the vehicle, security system, access to the car and proof of lawful ownership or authority.

See the spare car keys page for why arranging a spare before the last key is lost can reduce cost and disruption.
Do I need a genuine key from the dealer?

Some vehicles require or strongly benefit from a genuine key, while others can use a suitable high-quality aftermarket option. The recommended choice depends on compatibility, reliability, availability and the functions required.

For all keys lost, visit the lost car keys service page or text the vehicle details and location.
Will you program a key I bought online?

Customer-supplied keys may not be accepted because visually identical keys can use different frequencies, chips, electronics or firmware. Supplying a verified compatible key reduces the risk of failed programming and unreliable operation.

Can a flat key-fob battery stop the car from starting?

It can affect remote or proximity operation, but many vehicles provide an emergency starting method when the fob battery is flat. A completely unresponsive key may also have damage or an electronic fault, so the correct diagnosis depends on the vehicle.

What should I do if my keys are locked inside the car?

Call 0494 149 841 with the vehicle make, model, year and exact location. Do not force the door or use improvised tools, as modern vehicles can be damaged around the glass, trim, wiring or locking system.

Will unlocking the vehicle damage it?

Professional unlocking methods are selected to minimise the risk of damage, but the correct method depends on the vehicle design and condition. No responsible locksmith should promise that every lockout is identical or risk-free.

Do I need to prove I own the vehicle?

Identification and reasonable proof of lawful ownership or authority may be required before unlocking, originating or programming keys. This protects the vehicle owner and supports responsible security-related work.

How attendance works
