Ignition Interlock Cost

How Much Does an IID Cost?

If you've been convicted of a drunk driving offense, you may be required to install an ignition interlock device (IID), also known as a car breathalyzer. An IID is connected to your vehicle’s ignition system, and you must pass a Breath Alcohol Content (BrAC) test before the vehicle will start.

There are several costs involved with installing an ignition interlock device, and customers are responsible for all ignition interlock costs, including both installation and leasing fees. Your total IID cost depends on several factors, including:

  • The state requiring the IID
  • Your vehicle’s make and model
  • The type of device required by your state

Our specialists can provide a personalized quote based on your situation. We offer fast installation options, including same-day or next-day appointments, to get you back on the road as soon as possible.

Other Potential Interlock Fees

All fees are outlined in your Intoxalock lease agreement, including monthly lease costs and potential incidental fees:

Lockout Fee

If you fail multiple BrAC tests or tamper with the device, requiring remote support to unlock it, you may be charged a $75 lockout fee.

Vehicle Switch Fee

If you need to switch your interlock device to another vehicle during your term, a $30 fee applies.

Late Equipment Fee

At the end of your lease term, a $2 per day fee is charged for each day the device is not returned to the installation center.

IID Costs vs. Public Transit and Ride Shares

When compared to the costs of using public transportation or rideshare services like Uber or Lyft, an interlock device can often be a more affordable option.

  • Public Transit: Daily passes can cost $5–$6.25, and traveling to work and errands can require multiple trips.
  • Rideshares: A one-way ride during peak hours can cost $23 or more, easily adding up to $50 or more per day.

In contrast, an ignition interlock device, with lease rates starting as low as $1.83 per day, offers a cost-effective way to regain your driving privileges while keeping daily expenses manageable.
