    I wish I could give this place 0 starts. Worst place ever. I went with a friend to get their intoxalock devices installed as they advices beforehand it could take 1 to 1 1/2 max.... but we were there for over 4 hours. The “office” is filthy as if they never cleaned the place. Floor dirty. Dead roaches. Nasty couch and you can see the insulation through the roof. Wouldn’t recommend anyone to come here or even allow this place to operate. The guy doesn’t seem to know what to do and is on his phone as if he was on YouTube trying to learn how to do it or talking to someone taking him though the steps.

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.

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.
