    I have been a customer with DZ Customs for most of this year. The quality as well as customer service is next to none! They are responsive and attention to detail is their strength. I highly recommend.

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.
