    I used them for my Intoxalock service center, and they were the best company/experience I had through the entire process. Great customer service, friendly, and worked with me on many issues. Definitely recommend using them!!

    The guys at this location are awesome. Sam and Carlos are very customer service oriented and explain the process to my understanding. I glad I chose this dealer considering the fact that I have to have this in my vehicle.

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.

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.
