What an ignition interlock costs
Interlock programs in Florida are paid for by the driver, and the total cost depends on the provider you choose, your vehicle, and how long the device must stay installed. Rather than quoting numbers that go out of date quickly, this page explains the kinds of charges you should expect and how to compare offers fairly.
The main cost components
- Installation fee. A one-time charge for fitting the device to your vehicle. Some providers discount or waive it as part of a promotion, and then recover the difference in the monthly rate, so always look at the whole package.
- Monthly lease. The recurring charge for the device itself and the monitoring service. This is usually the largest part of the total cost over the life of the requirement.
- Calibration and service visits. Some providers include routine calibration in the monthly rate, while others bill each visit separately. Ask which model applies.
- Removal fee. A one-time charge at the end of the program for taking the device out and restoring the wiring.
- Incidental charges. Missed appointments, lockout resets, damaged mouthpieces, or early termination can carry extra fees. These are avoidable, but you should know they exist.
How to compare providers
The honest way to compare is total cost over your full required period. Multiply the monthly rate by the number of months, then add the installation and removal fees and any per-visit charges. A provider with a free installation offer but a higher monthly rate can end up more expensive than one with an upfront fee and a lower lease.
If cost is a hardship
Ask about payment plans, and ask the court whether any reduced-cost arrangements apply in your case. Some drivers qualify for assistance depending on income and the program they are in. It never hurts to ask both the provider and the court clerk what options exist.
