What to Expect During Your Interlock Installation

Before you arrive

Once you've been ordered to fit an interlock device by the court or Transport for NSW, contact us to book your installation. We'll confirm an appointment time and let you know what to bring:

• Your court order or NSW interlock program paperwork
• Your driver's licence
• Your vehicle registration papers
• Payment for the installation fee

We can usually fit you in quickly — same-day installation is often available. Call 02 9398 8817 to confirm availability.

How long does installation take?

Most installations take between 1.5 and 2.5 hours depending on the vehicle's wiring complexity. European vehicles and some modern cars can take a little longer. We'll give you a time estimate when you book.

You're welcome to wait at the centre or drop the car off and return later.

What happens during installation

Our licensed technicians will:

• Connect the Smart Start interlock unit to your vehicle's ignition system
• Mount the handset in a convenient location within the cabin
• Install the SSI G4 Photo ID camera module on the windshield (required by NSW RMS)
• Run a full calibration and systems check
• Test the device with you present before you leave

Training walkthrough

Before you drive away, we'll walk you through everything you need to know:

• How to give a correct breath sample (blow technique matters)
• How random retests work while you're driving
• What the different warning codes mean
• How to book your monthly service visits
• What to do in an emergency (Smart Start 24/7 hotline: 1300 256 900)

We also recommend watching the official Smart Start training video at home with anyone else who drives your vehicle.

After installation — monthly servicing

Your interlock must be serviced every 30–60 days (depending on your program conditions). At each service visit we:

• Download the data log from the device
• Recalibrate the unit
• Send the compliance report to Transport for NSW on your behalf
• Check for any faults or tamper events

Missing a service will put your vehicle into lockout — so it's important to keep your appointments. We'll send you a reminder.

Costs

Interlock costs in NSW typically include an installation fee and a monthly monitoring/lease fee. Smart Start offers some of the most competitive pricing in the state. Contact us for a quote — we're transparent about costs and there are no hidden fees.
