Why Interlock Pricing Isn't the Same for Everyone
Here's the thing. There is no "standard rate" that every driver pays.
Ignition interlock costs depend on a variety of factors, including, but not limited to:
- Your state's laws
- The specific interlock features your case requires (like camera or real-time reporting)
- Your vehicle
- The IID provider
- The service center you choose
- Incidental costs like non-passing breath tests or missed calibrations
Lease rates, installation and removal fees, and calibration charges can all vary by location and program rules—which is why you need a personalized quote based on your unique circumstances.

Short-Term vs. Long-Term IID Costs:
What to Expect
You may be tempted to focus on the first quote you hear, but that could be a costly mistake. Each interlock provider balances its own unique pricing model with state-mandated fees and service center fees.
You really want to examine the full picture of your IID costs throughout your requirements. These are examples of some of the most likely costs you'll incur over time, but variations are possible. Let our State Specialists run the numbers for you.
Immediate Costs (First 30–60 Days)
- Installation + Activation: One-time payments to the service center that can vary based on your vehicle and location, as well as an account activation payment.
- First month's lease payment: Think of this as a down payment for your first month of device use. Ask your Intoxalock state specialist about payment flexibility if needed.
- First calibration + Data processing: In some states, your first calibration may be included or discounted; in others, expect between $20–$30. There may be an additional fee for the data transfer during calibrations, too.
Ongoing Costs (During Your Entire IID Term)
- Monthly lease: This is your base monthly payment to keep your IID active. Most providers have a variety of flexible payment options so you can find the most convenient one for you.
- Calibrations: States mandate a device recalibration every 1–3 months. Although this is a small added routine expense, it does ensure your device is performing accurately and optimally.
- Removal: Once you successfully complete your interlock requirement, you'll need to schedule and pay for a removal appointment.
Potential fees (if they apply):
- Lockout fees may apply for repeated failed tests or tampering
- Towing costs if you experience a violation
- Vehicle switch fee if you change cars during your term
- Late equipment fee you may be charged if the device is not returned on time at the end of your lease
- Additional costs as needed
Myths vs. Facts: Ignition Interlock Pricing
Myth 1: “The Price You’re First Quoted Is Always Your Final Monthly Expense.”
Fact: Your base lease rate is only part of your total cost. Calibrations, possible lockout fees, and other charges may apply.
Why This Matters: You should always ask for a full cost breakdown, including calibrations and possible incidental fees, not just the lease rate.
Myth 2: “IID Providers Control All Costs and Fee Schedules.”
Fact: Prices vary by state, provider, required device type, and your vehicle. There is no single set price, and states may even dictate what to charge for certain types of fees.
Why This Matters: Two people in different states with different vehicles can pay different monthly amounts even with the same provider.
Myth 3: “There Is a Universal Installation Fee.”
Fact: Installation charges depend on the service center, your vehicle type, and local labor rates.
Why This Matters: Two shops in the same city can quote different installation fees because of so many variables.
Comparing Interlock Costs to Other Transportation
If you don't install an IID, you'll still need to get to work, court, and family obligations. Those costs can add up quickly.
- Public transit: Monthly passes can cost $25 to $132 depending on location according to Coastpay. They report the U.S. average public transit commute costs $600 annually.
- Rideshares: According to NetCredit, a 30-minute Uber ride can cost between $30.35 – $53.46 depending on the state and city. If you're on the high end of that spectrum, you may spend more than $100 a day commuting to and from work.
- Rental scooters: Don't assume these are a legal workaround. Many states treat these as "vehicles," which means DUI rules, license restrictions, and financial penalties can still apply.
With base lease rates starting at roughly $1.96 per day**, an Intoxalock IID is often the most cost effective way to legally drive yourself instead of relying on others. Rates vary by state and other required fees and considerations apply.
