    I had an interlock device put on my vehicle September the 16th, and I have not been able to start my vehicle since, but since this date I received a call from a young man named Daniel who has went above and beyond to help me get this issue resolved, I can’t express enough how helpful and supportive he has been, and how much I appreciate him taking the time he has to keep in contact with me, and responding to all my calls or emails, great customer service, and it’s been a great experience working with him, he has addressed any issues I had, and has provided a solution to get me back on the road. 100 percent satisfied with the customer service support I received, and would recommend this company to anyone.

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.
