    I’m very satisfied and pleased with this service and the staff is very polite understanding! The gentleman spoke very nicely to me on the phone and the towing was covered! You make it very easy for me while I’m going through my own consequences and difficult times!

    Did not show up on time for the appointment and cost me an extra $22 in uber fees. Did not honor the amount of installation at $200 until I called the owner of the shop. Would not recommend this shop

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.
