- AAAlyssa ArnesonAug 7, 20265.0This is our first experience with this business because we needed someone to install my husband’s interlock device. I can’t remember the receptionist’s name, but she is not only friendly and personable, but extremely informative regarding the interlock device. I took the car in on my husbands behalf while he was working and she walked me through every little thing in the booklet regarding lockouts, calibrations, what to do and what not to do, etc. and was super thorough so I could relay the information to my husband. During installation, she suggested getting a new battery because the life of ours was extremely low and informed that the device constantly runs on this and when I told her we needed to wait on that she wasn’t pushy at all. One of the shop guys came outside to show me how the device worked and explained how touchy it can be and also provided a few different tips and tricks such as putting the device in an oven mitt, (weather permitting.) He was friendly, informative, and made sure I was comfortable with how the device worked to have the ability to “teach” my husband. The second time I needed to contact them was to schedule a calibration a couple months later and the same receptionist was extremely patient with me during the 5 different times I called to get things figured out; (after she gave me the information I needed.) We don’t have experience with having extensive work done on our vehicle(s) here, but as far as providing services for Intoxalock (who have their own crappy reputation,) MaxxedOut Motorsports has been extremely helpful and professional while we were new to the whole thing and made sure not to leave any questions unanswered.

Frequently Asked Questions About Intoxalock Ignition Interlock
How does an interlock device work?
An ignition interlock device (IID) is a small breathalyzer installed in your vehicle to prevent it from starting if alcohol is detected on your breath. Before driving, you'll blow into the device. If your breath alcohol concentration (BrAC) is below the programmed limit, the car starts. Periodic retests occur during your trip to ensure continued compliance. To read more on Intoxalock, you can read our ignition interlock device guide.
What is the cost of an ignition interlock device?
The installation of an ignition interlock device, often called a car breathalyzer, typically costs between $70 and $150. This one-time fee is paid at the start of your lease and covers the service center's labor to install the device in your vehicle. Payment is made directly to the service center at the time of installation. For more on cost breakdowns, you can read our cost of ignition interlock device guide.
How do I use my interlock device?
Using an IID is simple. To start your vehicle, blow into the device as directed. If the device detects no alcohol, your car will start. You may be prompted for "rolling retests" while driving, where you’ll blow into the device again to confirm compliance. How-to videos are also available on the Intoxalock mobile app.
Where do I get an ignition interlock device?
Ignition interlock devices can be installed at certified service centers nationwide. Intoxalock offers a convenient network of locations and helps you schedule an installation appointment near you. Visit our Intoxalock locations page or call us to find the nearest service center and begin the installation process.
How long will my installation take?
Installing an ignition interlock device typically takes 1-2 hours, depending on your vehicle type. Certified technicians ensure the device is properly installed and provide you with training on how to use it. Contact Intoxalock for an appointment and an accurate time estimate for your installation.
What happens if I fail a breath test on my ignition interlock device?
If you fail a breath test, your vehicle will not start, and the device will log the event. Depending on your state’s regulations, multiple failed tests may trigger additional penalties, such as lockouts or reporting to your monitoring authority. Intoxalock devices allow you to retest after a short wait if alcohol is no longer detected. Always follow your state’s guidelines to remain compliant.
Can I install an ignition interlock device in a vehicle I don’t own?
Yes, in most cases, you can install an ignition interlock device in a vehicle you regularly drive, even if you’re not the registered owner. However, the vehicle owner must provide consent for the installation. Intoxalock works with you and the owner to ensure compliance with state regulations and the successful setup of the device.
What should I do if my ignition interlock device locks me out?
If your ignition interlock device locks you out, it’s usually due to missed tests, failed tests, or state-specific requirements. Intoxalock offers a simple lockout override process in most cases to help you get back on the road quickly. Contact Intoxalock customer support for assistance and to understand the steps needed to resolve the issue.
