We offer the easiest, cheapest, fastest, most reliable interlock device for your car. Period. Our ignition interlock program allows you to effortlessly accomplish your interlock obligations and get you back on the road!


Our alcohol interlock devices only require you to submit a simple, 3-second exhale breath sample. This 3-second straight blow system is less frustrating and more sanitary than other, older, models that our competitors use. Our sampling process removes the need for complicated breath patterns such as blow/hum, blow/suck/blow etc. and gets you on the road much quicker.


With our all-inclusive and transparent approach, you will never find a hidden fee. Our 24/7 customer service representatives will walk you through all of the pricing and send it to you in writing allowing you to be informed every step of the way! Don’t hesitate to reach out to our client support staff with any questions you may have.


Our interlock devices for cars have the fastest warm-up time on the market ensuring you can provide a breath sample almost immediately under any weather condition. Also, with our patented calibration system, it only takes approximately 5 minutes – a sixth of the overall time of other interlock devices on average.

Most Sanitary Interlock

All of our affordable ignition interlocks are thoroughly cleaned and tested at our headquarters prior to use. Our devices never go from client-to-client thus eliminating the potential for unsanitary devices. In addition, our straight-blow technology erases the need for you to inhale as many older devices on the market require. This straight-blow technology increases the sanitary nature of our devices as you will never have to inhale what others previously blew into the device. Not only does our latest technology assist in the health safety of our devices, it also decreases the number of failed tests because our devices give a 100% accurate reading each and every time.

How it Works

Using our alcohol interlock device is as easy as 1-2-3.

Step 1

Exhale into the mouthpiece for around 3 seconds at steady volume to submit a breath sample. A good way to think about it is to pretend you are blowing out birthday candles. Once you hear a click that signals it is time to stop blowing.

Step 2

The ignition interlock device internally reads your breath alcohol content (BrAC) and will flash on screen if you have passed or failed.

Step 3

If your BrAC is below your state’s legal limit, you're ready to hit the road and it will allow your car to start.

What is a Rolling Retest?

Dependent on your state, you will be required to submit a breath sample after you start your vehicle at random intervals. Our device notifies you by a beeping sound and flashing screen to take a test and gives you 7 minutes to provide the test which allows you to pull the vehicle over in a safe area and submit a test. It is important to always provide a sample when prompted because if you don’t, your interlock device may begin a lockout where you will not be able to start your car for a certain amount of time.
