    We called around getting quotes and ended up talking to Betty, at first she was super helpful and informative but then became extremely pushy about going with them after I told her multiple times it needed to be discussed with my husband, yes he was in the car with me but she wanted me to ask him while I was on the phone with her. I thought that was tacky and disrespectful putting me on the spot like this, especially involving a major decision that is not cheap at all. I was ready to talk you guys up to him and make an appointment for installation but I did not appreciate her pushiness and making me feel boxes in. The only way I could get off the phone with her after saying, multiple times I would talk to my husband and more than likely call back, was to just hang up. Maybe in the future respectful a clients right to shop around. I would hate for an actual good company to lose business because of this, even if you are commission based. If you aren’t willing to listen to me now then I don’t think you’ll be helpful when u actually choose to work with you.

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.
