About Preston Interlock Services

​

Preston Interlock Services is a family owned and run business, dedicated to providing exceptional customer service  during the installation, monitoring and removal process of the Dräger Alcohol Interlock System.

We have three conveniently located sites that work together to provide a fast, efficient  and professional service for our customers.

Our workshops are modern and custom built with all work carried out by experienced and fully trained and accredited technicians.

The Dräger Alcohol Interlock is a discreet unit that leaves no permanent holes in your vehicle, has quick start up times and a quick and easy breath technique.

We pride ourselves on providing  a comprehensive service so you walk away with confidence in both the Interlock system and your responsibilities during your Court or VicRoads appointed contract period.  No hidden fees that catch you out down the track with full disclosure at installation and copies of all your contract requirements.

Please contact us if you require any further information.
