- DMDevin MusketJun 3, 20251.0Don’t go here to get your Intoxalock calibrated. They’ll bend you over. Charging $70 when the standard is $20-30.
- JYJeremy L. YoakamJan 30, 20255.0They always are there even if I just show up. Good outfit
- AAAlex AltersMar 30, 20241.0If i could rate it 0 stars i would. Garbage device, garbage system, garbage service, garbage company. Pick literally any other company, you’ll save yourself a ton of headache
- RHRandy HarrisNov 5, 20221.0Scam artists. Quotes a price and then keeps asking for more money and holds your vehicle hostage if you won't pay it.
- EMElizabeth MinasJan 10, 20221.0The owner of the shop was a theif and a liar. Cost of install should have been $235. He said the was a 4% charge for using a debt card, ok about $9 roughly. He said $290 total, then charged my account $306. He also made a photo copy of my debit card and asked for my pin number which I refused to give him. Install should have taken 5 hours at the very most. It was not ready until 6 plus hours later. I was the only car they were working on. So I had to go back and pick it up today. Then he charged me another $170, which I told him to take out of the money he had already stolen from me. He is also very rude and pushy. He made it seem like it was my fault the car wasn't done on time and tried to rent me a car or charge me a delivery fee. What a crook, I don't know how he is still certified or on bussiness at all.
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.
