    Didn’t show me how to use it. Update. A specialist reached out to me and gave me a very detailed explanation on how to use the device. My initial review was based off of the onsite installation specialist and not an intoxalock specialist. Everyone with this specific company has been very helpful and supportive.

    Getting set up was great. But then I developed pneumonia and it took me days to get my vehicle back because I couldn’t breath well enough to blow into the device. My asthma is very bad and I feel I will have issues with the device. I have not been able to get back in contact with anyone either through phone or emails to discuss my breathing issues.

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.
