Ready to install?
If you are ready to install an ignition interlock, schedule your appointment today!
If you’ve been ordered to install an ignition interlock device (IID), the cost of it is likely one of your biggest concerns.
The reality is, most IIDs are similarly priced due to state-by-state requirements.
In many cases, an IID installation typically ranges from $70 to $150, with monthly leases generally being between $50 and $120 per month, and recurring calibration appointments to ensure your device’s hardware is fully up to date and correctly reading your breath samples. Once your IID program is complete, there will also be a one-time removal fee that generally ranges from $40-$100.
Keep in mind, the cheapest IID isn’t always the one with the lowest advertised price, as the total cost isn’t always obvious or immediate. The best bang for your buck is the IID that provides reliable service and transparent pricing, while helping you maintain compliance.
Explore IID costs and learn why prices vary, and discover ways to find the most affordable compliant option in your state. Understanding what you’re paying for can make it easier to compare providers and choose an option that fits your budget and needs.
Here’s what you need to know about ignition interlock device pricing at a glance:
Key takeaways
- Most IIDs are similarly priced due to state requirements.
- Program length drives your total cost more than any single fee.
- The lowest advertised price isn’t always the cheapest once hidden fees are factored in.
- Costs vary by state, and many states offer financial assistance for eligible drivers.
- You can lower your total by getting a quote upfront, avoiding unnecessary fees, and staying with one provider.
How Much Does an Ignition Interlock Device Cost?
The cost of an IID depends on several factors, including your state’s requirements, how long you need the device, and the fees charged by your provider. Some states regulate pricing or offer IID financial assistance, while others allow providers to set their own rates.
Here is what you can generally expect to pay:
Cost | Typical Price Range | What it Covers |
Installation Fee | About $70–$150 one-time | Installing and connecting the IID to your vehicle |
Monthly Lease Fee | About $50–$120 per month | Device rental, monitoring, and compliance reporting |
Calibration Appointments | About $25 every 1-3 months | Required service visits to maintain accuracy and compliance |
Removal Fee | About $40–$100 one-time | Removing the IID after your requirement ends |
Your total cost will depend largely on how long you are required to keep the device installed.
Someone with a six-month requirement will typically spend less overall than someone required to maintain an IID for several years.
What Factors Affect the Price of an Ignition Interlock Device?
When comparing cheap IIDs, it helps to look beyond the initial price. Several factors can affect what you ultimately pay, including:
- State requirements: Every state has its own IID regulations. Some states require additional features, such as cameras or GPS tracking, which can affect pricing. Providers must also use devices approved by the state where you are completing your program.
- Your vehicle: Most vehicles can be equipped with an IID, but installation costs vary based on the make, model, and electrical system. Newer vehicles with more advanced technology may require additional installation time or specialized equipment.
- Program length: The longer you are required to have an IID, the more monthly lease payments, calibration appointments, and monitoring fees you will pay.
- Provider pricing structure: Some companies advertise a low monthly rate but separate additional charges. Others include more services in one price. Comparing the full cost upfront can help you avoid unexpected expenses later.
Remember, the lowest-cost provider is not necessarily the most affordable choice if hidden fees, missed appointments, or service issues create additional expenses during your program.
What’s important is transparent pricing and knowing what to expect before installation. Look for a company that doesn’t, for example, charge an upfront fee to schedule an IID appointment. Make sure you’re charged for the service only once the IID is installed.
Why Does Ignition Interlock Pricing Vary by State?
Your state’s IID laws play a major role in determining cost. Requirements can vary based on factors such as your history, required program length, and the features your device must include.
For example, California requires state-approved IID providers and offers financial assistance options for qualifying drivers. In Texas, IID requirements and pricing vary based on court orders and individual circumstances. Arizona IID pricing is also dependent on its state-specific cost regulations.
Because IID programs are determined at the state level, the cheapest IID for one driver may not be the same option available to someone in another state.
Look for nationwide providers, like LifeSafer, that offer state-approved devices and certified installation support to ensure you meet your state’s requirements.
What If I Can’t Afford an Ignition Interlock Device?
If paying for an IID feels out of reach, you may qualify for financial assistance. Many states offer reduced-cost programs for drivers who meet income requirements, often based on federal poverty guidelines.
Examples of state assistance programs include:
- California offers reduced-cost IID assistance through the Bureau of Automotive Repair for eligible drivers.
- Colorado provides financial assistance through the DMV for qualifying drivers.
- Illinois offers financial assistance through the Secretary of State’s Breath Alcohol Ignition Interlock Device program.
- Nebraska provides financial support through its Ignition Interlock Indigent Fund.
- Wisconsin offers a 50% reduction for eligible drivers who meet income requirements.
Eligibility requirements vary, so it’s worth checking your state’s program before scheduling installation.
Tips for Getting the Lowest Total Cost on Your Ignition Interlock
Finding an affordable IID is about more than choosing the lowest monthly price. These steps can help you control your overall costs:
- Get a free quote before making a decision: A detailed quote helps you understand installation fees, monthly costs, and any required services before you commit.
- Choose a provider that does not charge unnecessary upfront fees: Some providers may charge a scheduling fee before installation. Look for a company that only charges you when your IID service begins.
- Select a convenient installation location: Regular calibration appointments are part of your IID requirement. Choosing a provider with accessible service locations can make it easier to stay on schedule and avoid potential compliance issues.
- Ask about financial assistance early: If you think you may qualify for reduced costs, apply before installation rather than waiting until payments become difficult.
- Avoid switching providers during your program: Changing your IID provider can require another installation and may create additional costs or paperwork. Choosing the right provider from the beginning can make your entire program run smoother.
