    48 hours has passed and waiting to get the device removed. My 90 days was up a week ago. Everything I call the customer service I get a different story about what is going on and how long it will take. I have hold on hold to take to a supervisor for over an hour. If this was not mandated by the courts, this company would be out of business. If I could give them 0 stars I would. They are a nightmare. Update Jan 2. The people from intoxalock called me today and did their best to make the situation right... so that is something, as far as it goes. Moving from 1 star to 3. The people at Garden State Truck and Auto are, and have been, outstanding through the whole process. I would give them 5 stars. I will continue to be a customer of theirs for regular tire and auto maintenance.

    Garden state has very professional and knowledgeable. My only complaint isn’t about the shop more the unit it’s self. It goes off during driving a lot more than other devices. And the mouth piece is absolutely horrible.

    Yes, I was speaking with Danica. We laughed the whole time. She made the experience less stressful and answered all my questions. My experience was unbelievably stress-free. Thank you Danica for all your help.

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.
