    Was given several documents that explained the intoxalock after it was installed by a woman at Dashboard.Acted as if she was in a hurry. Sign here initial here she said . She did not introduce herself . When she went to the van to explain how to blow into the handheld device she did not explain it so I could blow into it and start my van . I went back a few days later and started my van when dashboard was closed. She failed to tell me to inhale first. Instead she told me if I was a smoker I may not have enough breath to breathe into it. Said I would need to get a work order to recalibrate it!

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.
