    Upon the device being installed my security light now stays on 24/7. Will not go off. Never had any lights on this vehicle until this device was installed. Not to mention the shop couldn’t figure out what was going on with the installation, causing the vehicle to not start. They then called in a specialist that ended costing me over 500$ just to install. Who knows what they have done to my vehicles wiring, I know they cut wires and had my dash ripped apart, my dash wasn’t even properly put back together when I picked it up, I had to finish putting it back together myself. Hope this device and installation doesn’t affect the vehicle in the future.

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.
