How much does an interlock cost? A complete breakdown of expenses

4 min read

Ignition interlock devices (IIDs) have been proven to reduce re-arrest rates for drunk driving by 67% compared to license suspension alone. For those facing a court order, understanding how much does an interlock cost? is a critical first step toward compliance and regaining driving privileges. This total expense is not a single fee but a combination of several costs over time.

Quick Summary

Ignition interlock device costs typically involve initial installation, monthly leasing and monitoring, and calibration fees. Additional expenses can arise from device lockouts or removal, and the total price is influenced by state regulations, vehicle type, and the duration of the program.

Key Points

  • Total Cost: The total annual cost for an interlock typically ranges from $800 to over $2,000, factoring in all fees.

  • Primary Costs: Main expenses include a one-time installation fee ($70-$150), monthly lease fees ($60-$150), and recurring calibration charges ($20-$35).

  • Variable Pricing: Your total bill is affected by your state's specific laws, the make and model of your vehicle, and the duration of your program.

  • Additional Fees: You can incur penalty fees for failed tests, tampering, or missed appointments, ranging from $35 to $150 per incident.

  • Financial Aid: Many states offer financial assistance or subsidies for low-income individuals to help cover IID costs.

  • Leasing vs. Buying: Interlock devices are leased, not purchased, and must be removed by a certified technician at the end of the program, for an additional fee.

A detailed breakdown of ignition interlock device costs

An ignition interlock device (IID) is a small breathalyzer-like device wired to a vehicle's ignition system. It prevents the engine from starting if it detects alcohol above a pre-set limit. While the specific costs can vary significantly by state and provider, they generally fall into several distinct categories.

Installation fees

This is a one-time fee paid to a certified service center to physically install the device in your vehicle.

  • Typical Cost: Installation generally ranges from $70 to $150.
  • Factors Affecting Cost: The make, model, and year of your vehicle can influence this price. Newer vehicles with more complex wiring systems, or hybrid/electric models, may require more labor and result in a higher fee.

Monthly lease and monitoring fees

Rather than purchasing the device outright, you will lease it from a certified provider for the duration of your court-ordered program.

  • Typical Cost: Monthly lease fees typically range from $60 to $90. Some companies may charge as much as $120 or $150 per month.
  • What it Covers: This fee covers the lease of the device, data reporting to the monitoring authority, and maintenance. Some providers may offer flexible payment options, such as bi-weekly payments.

Calibration fees

To ensure accuracy, the IID must be calibrated regularly, usually every 30 to 90 days, depending on your state's requirements.

  • Typical Cost: Calibration fees are often a separate charge, averaging around $20 to $35 per visit. Some providers may include this cost in the monthly lease fee.

Removal fees

Once you have successfully completed your interlock program, you will need to pay for the device to be professionally removed from your vehicle.

  • Typical Cost: Removal fees are often similar to installation costs, ranging from $50 to $150. Some states or providers may offer free removal under certain circumstances.

Potential additional and penalty fees

Beyond the standard costs, you may incur additional fees for non-compliance or optional services.

  • Violation Lockout Fee: If you fail a test or attempt to tamper with the device, it may enter a “lockout” period, requiring a service visit and incurring a fee, often ranging from $50 to $150.
  • Missed Appointment Fee: Failing to show up for a scheduled calibration or service visit can lead to a missed appointment fee, which may be around $35.
  • Device Protection Plan: Some providers offer an optional monthly insurance plan to cover damage or theft of the device, which costs around $8 to $10 per month.
  • State-Specific Requirements: Certain states may require additional features like a camera or GPS, which can increase the monthly cost.

Cost comparison table: Leading interlock providers

To illustrate the typical cost variations, here is a comparison based on information from major providers mentioned in search results.

Cost Component Intoxalock LifeSafer Low Cost Interlock
Installation Fee Varies by location $70–$150 $70–$150
Monthly Lease Starts at $54.99 $50–$120 $60–$90

Removal Fee Varies $50–$150 $129.50

Note: These are estimated costs and can change based on location and specific program requirements. It is always recommended to contact a provider directly for a precise quote.

How financial assistance can help

Many states recognize that the cost of an IID can be a financial burden. For individuals who cannot afford the full price, many states offer financial assistance programs. Eligibility is typically determined by factors such as household income, eligibility for federal aid (like SNAP benefits), or employment status. It is important to contact your state's monitoring authority or the interlock provider to discuss your options. Some providers also offer their own payment plans or coupons to help manage the expense.

Choosing the right interlock provider

With several certified IID providers available, choosing the right one is about more than just the lowest price. Consider the following:

  • Reputation and Reviews: Look for providers with a strong track record of reliability and good customer service. The search results include mentions of well-established companies like Intoxalock and LifeSafer.
  • Hidden Fees: Ensure the company provides transparent, upfront pricing to avoid unexpected charges later.
  • Customer Support: Check if they offer 24/7 support, as you may need assistance with the device at any time.
  • Local Service Centers: The convenience of local service centers for installation, calibration, and removal can be a major benefit.
  • Flexible Payments: Explore options for monthly or bi-weekly payments to fit your budget.

Conclusion: Weighing the costs and achieving compliance

For those mandated to use an ignition interlock device, the total expense can range from several hundred to over a thousand dollars annually when considering installation, monthly lease, and calibration fees. However, this is a legal and public health safety measure that provides a pathway to resuming driving privileges responsibly. Compared to the severe financial and legal consequences of a DUI conviction, such as higher fines, legal fees, or repeated offenses, the investment in an interlock is a necessary and, in the long run, more affordable step toward a resolution. Understanding the various cost components and leveraging financial aid options can make the process more manageable.
