NSW Interlock Service Centres | Guardian Interlock

Guardian Interlock provides interlock services via our vast network of trained service centres across Australia. Our Service Centres provide installation, servicing and removal of interlocks as part of government-mandated interlock programs/schemes.

Guardian Interlock’s approved service centres handle the proper installation of interlock devices in vehicles. Once your appointment is booked, you will receive a secure link to complete all pre-installation paperwork and online training in advance—so you arrive fully prepared. On the day of your appointment, our technicians will complete the installation and provide hands-on training to ensure you understand how to operate the device with confidence.
