    I'm glad to be on this device. Also thankful for the cop that pulled me over. It has helped me stopped drinking. I only started drinking 5 years ago after I lost my sister. I have avoided family because my religion prohibits alcohol completely. I have been alcohol free since the 22nd of June. Thank you and Allah bless.

    This company is absolutely horrible to get in touch with. It is currently 12:45pm on a Wednesday. I have been on hold for 45 minutes and have tried the live chat option at least a dozen times with no response. It is like this every single time I try to get ahold of someone here. If you find yourself in the unfortunate position of needing an ignition interlock, do your self a favor and find any other company. I wouldn't recommend intoxilock to my worst enemy. The only reason a company like this can stay in business is because it is state mandated and people don't know that there are other options.

    USE ANY OTHER COMPANY FOR INTERLOCK SERVICES. THESE PEOPLE IN PARTICULAR ARE THE ABSOLUTE WORST. I HAVE HAD TO DEAL WITH THEM FOR ALMOST 5 YEARS AND REGREAT EVER USING THIS COMPANY. I SUGGEST SMARTSTART IF ANY AS INTOXALOCK ARE FULL OF ARELESS INDIVIDUALS THAT SOLELY CARE ABOUT YOUR MONEY

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.
