    Intoxalock is a scam. I just had the system installed in my vehicle five days ago. I drove six miles home. I prepaid the next seven months. And attempted to fill out the contract. It gives me an option of giving them my account number where they can draw money out at will or paying as I go. When I attempt to check the box to pay as I go, it will not let you. I spoke with many foreign individuals over two days, trying to figure out why. Meanwhile my vehicle will not start. I've had them instruct meat how to check everything out unhooking.The battery unhooking the device.They do not know why it won't start. I had to pay out of my pocket to have my vehicle hauled to the installer by wrecker. We found out the vehicle is not starting because I have not signed the contract. It is a scam. I have paid everything as far as I can in advance. And I just do not want to give anybody my checking account number that they can draw out of at will. However, that seems to be all this company wants to do. You can't call the courthouse, no one answers. You can't call your probation officer.No one answers. You just leave messages days on end. SCAM !

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.
