About Interlock Sydney

Who we are

Interlock Sydney is the alcohol interlock division of Randwick Auto Electricians — an established Sydney auto electrical business with over 30 years of hands-on experience servicing vehicles across the Eastern Suburbs and greater Sydney.

Under the same ownership and operating from the same workshop at 3/68 Frenchmans Road, Randwick, Interlock Sydney brings that depth of automotive expertise directly to the NSW Alcohol Interlock Program. Our licensed auto electricians have the skills and experience to fit interlock devices correctly and safely to virtually every vehicle on Australian roads.

Our accreditation

We are an Accredited Interlock Service Provider for Smart Start Interlocks Australia — the Australian franchisee of Smart Start Inc., North America's leader in alcohol ignition interlock technology. This accreditation means:

• Our installations meet all NSW Government and Transport for NSW requirements
• Every device is calibrated and fitted by qualified auto electricians
• We submit compliance data to Transport for NSW on your behalf at every service
• You have access to Smart Start's 24/7 emergency helpline on 1300 256 900

Why experience matters for interlock fitting

Fitting an alcohol interlock device is an auto electrical job — not just a plug-and-play accessory. The device must be wired into your vehicle's ignition system, correctly interfaced with the ECU, and calibrated precisely. Poor installation can cause false lockouts, device failures, and compliance issues with Transport for NSW.

With over 30 years of auto electrical experience behind us, we have worked on virtually every make and model sold in Australia — from European prestige vehicles to Japanese 4WDs and light commercial vans. That breadth of experience means your interlock is fitted right, first time, with same-day turnaround in most cases.

Same-day fitting, same Randwick address

Our workshop is open Monday to Friday 8:00am–4:30pm and Saturday 8:00am–10:30am. We aim to fit your interlock device the same day you book — drop the car off in the morning, drive away in the afternoon. Book your installation or call 02 9398 8817.
