Breakdown of Car Breathalyzer Costs

Breakdown of Car Breathalyzer Costs

Originally published on 9/18/2018; updated on 10/24/2019.

When you discover you need to install a car breathalyzer, your first question is probably how much will it cost? Being charged with a drunk driving offense can be costly, so you don’t want to spend a large amount of money on the device that will keep you on the road. So, let’s break it down.

Monthly Lease

Because most ignition interlock devices, or car breathalyzers, are needed only temporarily, you will lease the interlock from Intoxalock for however long you are required to have the device. That length of time varies according to your drunk driving offense and your state’s regulations. The monthly cost also varies and is determined by:

·       Year, make and model of your car

·       State of residence

·       Length of time your device is installed

·       Features your state requires the device to have (GPS, camera, real-time reporting)

You can expect to pay a “rental” fee to lease the device of between $60–$90 a month for your Intoxalock IID. Call our state experts at (833) 623-0200 to secure the best price.

Monitoring and Reporting

Intoxalock works with each state to provide the required reports and documents surrounding ignition interlock usage. Our unique team of State Compliance Specialists continuously reviews each individual account to ensure you are meeting state regulations.

This is all included in the overall cost and is something that makes Intoxalock stand apart from the competitors. This level of detail creates a much smoother process for you, from start to finish.


Intoxalock is committed to making the installation process convenient for our customers. We have thousands of certified installers nationwide — twice as many as our competition. Our installers go through continuous training and are held to high standards so that every device installation is done properly.

You can expect installation of your device to cost between $70–$100, depending on the vehicle, the breathalyzer installed and your state. It’s important to note that your installation fee gets paid directly to your service center, not to Intoxalock.
