California (CA) - State Requirements - Ignition Interlock Device Cost

How Much Does an Ignition Interlock Device (IID) Cost in California?

The price of an Intoxalock Ignition Interlock device (also known as a car breathalyzer or IID) in the state of California is $99-$116 a month. Your IID cost is determined by:

  • Features you are required to have (camera, real-time reporting, GPS, etc.)
  • How long you need to have the device installed for
  • Ignition interlock provider you choose

All ignition interlock providers will have pricing for your installation, removal, monthly lease, and routine calibrations.

Financial Assistance for Ignition Interlock Devices in CA

Intoxalock offers financial assistance to all pilot program participants in the state of California. This reduced installation cost is determined by the income of the family installing the ignition interlock device. Annual household income is compared to the federal poverty guidelines and the amount of financial assistance is determined.

  • If the family’s income is 100% or below the federal poverty level, the customer pays 10% of the ignition interlock costs
  • If the family’s income is 101% to 200% of the federal poverty level, the customer pays 25% of the ignition interlock costs
  • If the family’s income is 201% to 300% of the federal poverty level, the customer pays 50% of the ignition interlock costs

If the court determines that you qualify for financial assistance, they will provide documentation directly to Intoxalock. In all instances, Intoxalock pays for the remaining balances not covered by the customer.
