    Update: I am pleased that the issue was resolved just a few hours after the company was made aware of the review. The gentleman was professional, apologized and made the situation right. No company is perfect, however when they are made aware and quickly rectify a situation that says a lot. I am changing my 1 star to a 4. Original review: Employee was calling all day every day, acting so helpful, until the money was paid (and I'm assuming Kristen got her commission) then she was no longer available. She entered the wrong VIN so the wrong vehicle was put on the account. Tried to absolutely no avail to get it changed. We couldn't get a hold of Kristen to save our lives. Emails and voice mails are still going unanswered. Spoke to someone else at the company, he changed the vehicle from the wrong make and model of truck to now an Airstream?! However we are still being badgered to sign the lease. A lease isn't getting signed when its stating the wrong vehicle. So yeah maybe think about using another company. Can't say much for the actual product, but I can say if you did need assistance with it I wouldn't count on getting it from them. Do your research and find a good product AND good customer service. This ain't the one, fam.

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.
