About Guardian Interlock Systems

Guardian Interlock Systems, found online at, says they are the leading manufacturer of affordable, high quality Breath Alcohol Ignition Interlock Devices for more than 30 years.  

How Does It Work?

In the United States, many people often find themselves in a situation where they have received or are under suspicion of a legal designation of driving under the influence. As such, many courts have given these people the ability to drive for prescribed periods of time as long as their car is fitted with a Breath Alcohol Ignition Interlock Device.

Guardian Interlock Systems says that their devices regularly help drivers get their driving privileges restored. In addition, they say their devices not only meet and exceed the National Highway Traffic Safety Administration specifications.

But perhaps more importantly, they also say they understand the financial hardship this situation places on people. Because of this, they have tried to make their device as affordable as possible.  

Cost/Price Plans

While the website does not say exactly how much their device costs, their Frequently Asked Questions page says that their price generally boils down to about $2 per day that you must use the device. 

Refund Policy

The website does not provide any information about potential refunds, though customers who feel as though they have encountered circumstances that justify a refund should contact their Customer Service right away.   

Customer Service Contact Info

Customers who would like to contact Customer Service with any questions, concerns, or complaints can do so by phone at 800-499-0994, by email at, or by submitting them to their website.


This company says that they have helped hundreds of thousands of clients and that follow up studies have shown that users of Guardian Interlock Systems not only regain driving privileges but keep them for long periods of time after their devices have been removed.

Competitors and Alternatives?

It is likely that there is more than one company that works as a provider of these devices, depending on the state you live in.
