    I dealt with Mike and he could not have been any more professional. He was quick, but made sure I left with a full understanding of how the system worked. It's a bit out of my way, but I will definitely return to him for my calibration! Hands down, a truly good man.

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.
