    Intoxaloc is a scam company do your research before there are plenty of people going through the same bs I'm going through they suck every dollar out of you and make it impossible to complete the program till you pay them 10x what they told you it would be I'm at the point where I have to get a lawyer. I've had no violations but yet they won't give me my certificate of completing the program it's almost 2025 everything is recorded so lawsuits coming because this is not a fair system

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.

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.
