    They are the best. They are really nice people to deal with. If there are any complaints it's because of the provider not them. They are just trying to make all there customers happy as best they can. So yeah, I would 100% recommend them.

    They guys in Elizabethton got me back on the road after the tech at dashboard audio cut all my wires too short to my ignition causing it to short out and lock my security system down on my car. When the tech in Elizabethton looked at my car he fixed all the loose wires and unlocked the car. I recommend u make the trip to see them if u want ur car done right.

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.
