- WWWilliam WrenFeb 23, 20265.0EXCELLENT & FRIENDLY SERVICE
- GMGerardo MorenoJan 20, 20265.0Jag at audio house was very professional and very helpful when I went to go pick up my truck explained to me clear instructions and showed me how to operate my breathalyzer, definitely a 5 start
- JSJames Cowan Sr.Nov 11, 20255.0Repeated issues with the device has caused lockouts and Intoxalock agreed to cover towing cost and reimbursement They lied and deceived me after the fact and still never reimbursed me over $400 even after their device was shown to be defective and had to be replaced. Isaias promptly called and took care of the issue immediately and was supremely helpful. My 1 star became a 5 star easily
- AAa agNov 18, 20244.0My Dl920 for was sent out without all my information printed out twice. Luckily a lead team member followed up and helped me take care of the situation. The entire ordeal took about 3 weeks to resolve. I really appreciate the team leads help.
- HCHugh CNov 4, 20223.0Not too happy. With a 10:00am appointment, I finally got my truck back with the IID installed at the end of 2 days later. It takes 2 hours to install one. I almost understand working on someone else's audio installation instead of a "drunk's" pickup, but they don't know it's my first..and last DUI, and I haven't had an alcoholic drink in a year and a half nor do I ever plan to have one! Prejudice still wins out in the world. Not too happy with the length of time it took to install.
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.
