    Quick to collect your money. Once they get it. Good luck trying to get ahold of someone? The installer at 52nd and wadsworth is really shady. I was told everything was paid for. After he installed my device in my truck. He said I had to pay him. Another $320.00 dollars. He wanted Me to pay by zelle. Cash app. And would not provide a receipt. I did not pay. I was told from intox that everything was paid for. Now I am stuck with terrible service so far. They also tried to charge me $41.00 for shipping? Ship what? Lol. Ask questions. Watch your billing?

    Your people don’t know what they are doing or talking about. I’m sitting here with CO dmv with my paper work and your csr’s are telling the dmv they are wrong.

    This company and service providers suck. I was charged $400 the first week because the unit was faulty and lockouts. Was told it would be refunded and it wasn't. Paid the early termination fee on a contract that was never signed. Cancelled my card because I suspected they would continue charging me which they did even though I paid to cancel the service. C.O.M. interlock is a greedy bas**rd as well. Go to SmartStart.

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.
