    Terrible experience! The first rep I talked to said I could get next day installation. That was wrong. I finally got instal scheduled only to get a call and email saying it was pushed up to an earlier day. I drove an hour to that auto station only to find it wasn’t even open. The person I spoke with said they had no record of changing my appointment and couldn’t do anything about it. I decided to bypass Intoxalock and I called the original location to keep the appointment I originally had. After spending 8 hours at the auto shop Intoxalock technical support couldn’t get them the right wiring and I had to leave and bring my car back yet again! I spent over 13 hours trying to get the IID installed and Intoxalock said because I got a $100 service rebate that there wasn’t anything else they could do. They own another company for IID so there aren’t many options, but the communication and way all of my installation was handled was a nightmare!!!

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.
