    James was very knowledgeable and was able to get an install date pretty quick. He did tell us that the unit we would get did not have to be hummed into, but low and behold it did. That was quite unfortunate and we probably would've shopped around had we known this is what we would've received. Very disappointed.

    Friendly, knowledgeable and courteous. I would definitely recommend Johnny’s Auto Machine for anyone needing to have one installed.

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.
