- SSSteveMay 23, 20265.0Quick installation with a great explanation on how to use device. I highly recommend this place.
- GAGus AguilarAug 29, 20251.0Always finding ways take pay you charge extra fees on top of the high payments. I you miss a test at the time giving and you do it a minute later because you're driving it gives you a penalty fee. You check on calibration dates and doe not give a date. You miss the date and you have to pay a fee. The exact lease amount that you pay bi-weekly that was given initially the day you signed varies on I don't know what. Poor customer service and most of the time it is hard to communicate with the operators. Too much of a hassle and fees.
- JRJimmy RhoneNov 8, 20245.0Device installed so poorly that it fell out from under the dash the first hour. Device not calibrated correctly and has locked me out. Just spent over 300$ for this debacle. Isaiah did a great job unraveling this for me. Of course I have to drive to Sacramento to have this removed as premier audio will never see my car again. Complete hacks. You should review your subcontractors. Also defective device noted I didn't get the ignition lockout fixed for 4 days in less than 24 hours of it being in my car. Isaiah is the only reason I'm not calling the better business beaurogh on this company. 5 stars to Isaiah. Zero stars to this company
- SNSean NolanNov 7, 20241.0I gave my card info over the phone for this service and shortly after my bank card was used 4 seperate times back to back in two days for Uber eats at a total of $275.00 This service should have been online and I am very pissed off.

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.

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.

Contact Intoxalock customer support for assistance and to understand the steps needed to resolve the issue.
