What Our Customers Say About Us

Mistakes happen to us all

Mistakes happen to us all, but when representatives of the company helps one recover from self blunders it is a wondrous thing to behold. Samantha assisted me (and made super easy I might add) with paying my bill this morning even after I got in my own way with a scattered brain. Thank you very much for not letting this be an issue, as I certainly will not become a recurring issue for you myself.

This has been a very stressful…

This has been a very stressful situation; however Ryan at extension #7203 has made this a ray of light. The DMV kept sending me to court for an outstanding fee, then the court would send me back to the DMV. That happened 3 times. I was beginning to lose hope; but Ryan not only was efficient at his job, but patience with me and went above and beyond to contact (or have someone contact the DMV) and clarify everything. He is AMAZING!!!!

I have been with Low Cost Interlock…

I have been with Low Cost Interlock since March of 2018. They reimbursed me the cost to install the interlock device. I have had no problems with the device. The staff is super friendly and helpful. I go to my DUI classes and always recommend that my class mates check out Low Cost Interlock.

Guaranteed Lowest Price. Period. Call Now!

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


Our alcohol ignition 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 test 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 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 ignition interlock systems 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.

The Benefits


Our alcohol ignition interlock devices use the latest technology to ensure your breath sample readings are 100% accurate every time thus reducing device errors which saves you time (and money) and limits your overall time in the interlock program.


Our ignition interlock system for your car is the fastest on the market. Period. The car breathalyzers we offer have exclusive heating features that can save you up to 5 minutes every time you start your vehicle, under any temperature.


With hundreds of locations nationwide, we offer the ease of servicing your interlock ignition system in just minutes from your home; making our device and service as convenient as possible for everyone!

Customer Care

We offer fast installation and calibration services, and equip you with a bilingual onboard countdown, accompanied by texts and email notifications to make sure you understand the entire process.


We're here to make sure all of your questions are answered.

How do Payments Work?

At Low Cost Interlock, our goal is to make the ignition interlock process as easy as possible for you, which is why we ensured that our payment system is fast and convenient. We accept prepaid credit cards, credit cards, and debit cards. You will be charged each billing period for the total amount due for that period. A receipt will be emailed to you and the charge will appear on your credit card statement.

Are there any hidden fees?

There are absolutely NO hidden fees with Low Cost Interlock®. Unlike other companies, we do not charge lockout or reset fees for missed or failed breath tests. In addition to our upfront pricing approach, we offer 24/7 technical support. Contact us today with any questions about our interlock devices, the interlock process or about our ignition interlock pricing.

What is a Rolling Retest?

Dependent on the ignition interlock laws in your jurisdiction, 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.
