    My experience with this company was disappointing. Despite multiple attempts to schedule an appointment, the representative repeatedly claimed he had no availability or space for my Intoxalock calibration. Additionally, I later discovered that this location overcharges by an extra eight dollars compared to another service provider. I will not be going back.

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.
