    I wouldn't recommend Intoxalock to anybody. They tried to make me go 2 years when I only needed 1. I had to send them a second copy of my court order, call them a dozen times, and threaten to call an attorney for an appointment to remove my device. Then they canceled my appointment and didn't tell me anything about it. I had them make another appointment for me and they told me it would be an unauthorized removal. DON'T USE INTOXALOCK!

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.
