How Much Does an Interlock Device Cost?

Interlock drivers are required to pay for the cost of their device, though some states offer financial assistance to those who qualify. The costs vary by state, but typically an IID will cost between $70 and $150 to install. After installation, users will pay the average monthly lease price of $60 to $90.

The installation fees cover the cost of having the device properly installed by a state-certified installation technician. The technician will also show you how your device works and provide any necessary paperwork you need. Some states require proof of installation before issuing an IID license.

Monthly lease fees cover the use of the device and the monthly reporting required by all states. The cost for devices can vary depending on state requirements, like a camera or GPS. Our advisors can help determine your total costs and what device meets your state’s criteria.

Many states offer financial assistance, and an interlock advisor can help determine if you qualify.
