    G&A truck repair installation location has been very helpful and great to work with.. it's the Intoxalock company itself is a different story... the representatives were NOT!!!!! ONE flat out lied about the ease of use... and Wouldn't let ME make an informed decision about wanting to look up information of OTHER COMPANIES. I was RUSHED and made to feel like I had no other option.. I WISH I had NEVER CHOSEN INTOXALOCK... WHAT A SHAM........

    The language barrier that does exist is at the top end of extreme. Very very difficult. Just saying

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. 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.
