Guardian Interlock Device

Refining 20 years of progress in the BAIID industry, our parent company, Guardian Interlock, has developed the industry’s most advanced interlock system.

Our interlock system fits into your vehicle without taking over. Its sleek, ergonomic design means convenience for you, and its accurate, reliable systems mean clear data for our technicians and the state.

Our unique detachable handset allows you to simply remove the unit from your vehicle when it needs serviced. By maintaining an operating system apart from your vehicle, we save you the effort and expense of having the whole thing towed to a service center for a simple recalibration.
