    I had an interlock device put on my vehicle September the 16th, and I have not been able to start my vehicle since, customer service was horrible and I still can’t get my vehicle to start. I don’t recommend this place for anything, my vehicle was running fine when I dropped it off there and when I went to pick it up I was advised to keep blowing in it until I got it started but I ended up having to leave it there because I couldn’t get it to start and again they were no help and I still can’t start my car.

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.
