    The specialist was excellent. Can’t say the same about Intoxalock’s devices though. The specialist told me that these will give “false positives” and that it’s common. If you shut your vehicle off for 3 mins and it’s cold outside, it has to “warm up” from anywhere to 20 seconds to 5 mins. The device looks like a GameBoy, but the size of a god damn brick. Almost got into an accident because I was concentrating on blowing into the device correctly. But the guy that installed knew his stuff. Couldn’t have asked for a better technician. Service is great, but the technology is horrible.

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.
