    Tony did an excellent job on the install! When I ran in to issues with a bad relay in the unit he was quick to fix it and get me back on the road!

    I wasn't informed about the cost of installing this. I thought all I had to pay the day of installation was the $29.99 agreed to and paid over the phone. But, I was given a call and an apology, which was also given in an email. The situation was handled very professionally and positively in my favor. I was also able to replace the hand held device, which was having problems initiating. The new one works great! The $260 fee was reimbursed and credited to my account. Thanks for the excellent service.

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.
