Most installations are completed the same day you call, and we schedule monthly maintenance at times that work around your job and family commitments. At Auto DR, we're not just installing a device—we're supporting you through the entire journey toward license restoration.

Understanding Michigan Ignition Interlock Requirements & Your Restricted License
If you've received an OWI conviction in Michigan, the Michigan Secretary of State may require you to install an ignition interlock device (also called a car breathalyzer) as a condition of obtaining a restricted license. This isn't about punishment—it's about demonstrating your commitment to sobriety while maintaining the ability to drive to work, medical appointments, and other essential locations. Understanding exactly what's required helps you navigate this process with confidence rather than confusion.
Many drivers don't realize that ignition interlock programs represent genuine opportunity. By successfully completing your program requirements, you're actively working toward a full license restoration. The Intoxalock device measures your breath alcohol level before allowing the engine to start, and it requires periodic "rolling retests" while you're driving—random breath samples that ensure continued sobriety throughout your trip. These requirements might seem strict, but they're designed to keep Michigan roads safe while giving you a second chance.
Common situations requiring an ignition interlock installation include:
- Court-ordered installation following OWI conviction
- License restoration appeal conditions set by a hearing officer
- Sobriety court program participation
- Specialty court mandates through drug treatment or veterans courts
Your specific requirements will be detailed in your court order or restricted license documentation, but our team can answer questions about the installation process and ongoing compliance needs.
Some drivers ask about the difference between auto breathalyzer, car breathalyzer, and ignition interlock device. These terms all refer to the same thing—the device installed in your vehicle that prevents operation if alcohol is detected in your breath. Different manufacturers and courts use different terminology, but the function remains identical across all devices and brands.
Where Can I Get an Intoxalock Device Installed?
At Auto DR, we're a certified Intoxalock installation and service center. Intoxalock devices meet all Michigan compliance requirements and feature industry-leading reliability and customer support. As an authorized provider, our technicians are extensively trained on every aspect of the installation, maintenance, and calibration processes. We deliver the expertise you can trust throughout your entire program.
Intoxalock Installation Services
Our certified technicians have the manufacturer-specific training and equipment to complete your installation correctly. We integrate the device with your vehicle's electrical system using manufacturer-approved connection methods that won't damage factory components or void warranties. Each installation includes proper device mounting and electrical integration, precision calibration ensuring accurate breath testing from day one, tamper-proof seals meeting Michigan Secretary of State requirements, comprehensive training on device operation and rolling retest procedures, and certificate of installation for court or license restoration documentation.
Vehicle Compatibility & Installation Process
We've installed ignition interlock devices on virtually every vehicle make and model—domestic and foreign vehicles, sedans and trucks, older models and newer vehicles with complex electronics. Some vehicles require specialized approaches: diesel engines, push-button start systems, hybrids, and vehicles with aftermarket remote starters each need specific installation procedures. Our technicians understand these requirements and adapt accordingly.
During the installation, we inspect your vehicle's electrical system, integrate the device using proper wiring methods, calibrate for accuracy, install required tamper seals, and test complete operation before you leave. We explain how your specific device works, what to expect during rolling retests, and answer any questions about your manufacturer's unique features.
Troubleshooting Ignition Interlock Problems & Emergency Service
Device issues shouldn't derail your progress. Whether you're seeing error codes, experiencing calibration concerns, or dealing with unexpected device behavior, our certified technicians diagnose problems quickly and provide solutions that keep you compliant and on the road. Understanding common ignition interlock problems helps you recognize when professional service is necessary versus when a simple device reset resolves the issue.
Common ignition interlock device problems include:
- Device won't start or fails to activate when you try starting your vehicle
- Error codes displaying on the device screen without clear explanations
- Calibration drift causing inconsistent readings
- Rolling retest failures for unclear reasons
- Device lockout situations where your vehicle won't start despite providing breath samples
- Electrical problems affecting device power or operation
- Physical damage from accidents, extreme temperatures, or normal wear
Frequently Asked
Questions
How long does it take to install an interlock device?
For most vehicles, the installation can be completed within a few hours. We complete same-day installations in the majority of cases, which means you can have your device up and running the same day you contact us. We'll explain the entire timeline when you call, and we'll work around your schedule to minimize any inconvenience.
How much does an ignition interlock device cost?
The cost depends on several factors specific to your situation, including the specific Intoxalock device you need, your vehicle make and model, and the length of your program requirements. Rather than giving you a generic quote that might not apply to your situation, we invite you to contact Auto DR for an honest cost conversation. Our technicians will review your specific needs, explain what's included in installation and ongoing monthly maintenance, and provide transparent pricing with no hidden fees or surprises.
Why is my car breathalyzer not working?
Common reasons include dead or low battery in the handheld device, loose electrical connections between the device and your vehicle, calibration drift causing false readings, software glitches requiring professional reset, or internal component failure. Only proper diagnostic testing determines the actual cause and appropriate solution. Attempting DIY troubleshooting risks creating additional problems and potentially violating your program requirements—manufacturer seals must remain intact, and unauthorized device tampering results in serious compliance violations.
Understanding Interlock Error Codes and What They Mean
Your device displays error codes when it detects malfunctions or system issues. Some codes are minor—they might require simply turning your vehicle off and restarting it—while others indicate serious problems requiring immediate professional attention. Without proper diagnostic equipment and manufacturer training, you can't distinguish between codes you can safely address yourself and those requiring professional service. Ignoring serious error codes puts you at compliance risk and could result in device lockout or program violations.
If you experience ignition interlock lockout—when your device prevents vehicle operation—contact us immediately. Lockout situations require understanding why the failure occurred and whether device issues played a role versus legitimate detection of alcohol or inability to provide an adequate breath sample. Our technicians can review your test data, determine if calibration problems affected results, and restore device operation quickly while ensuring you remain compliant with program requirements.
Why Professional Installation & Maintenance Prevents Violations
Improper device handling, delayed maintenance, or misdiagnosed problems can result in interlock violations—serious consequences that include license suspension, program restart requirements, and extended ignition interlock periods. Michigan treats violations seriously because they indicate either continued alcohol use or failure to follow program requirements. Understanding how professional service protects you from violations helps explain why choosing a qualified, certified provider matters so much.
Violations typically fall into two categories: minor and major. Minor violations might include missing scheduled maintenance appointments even by a few days, device lockouts from failed rolling retests, or calibration issues that weren't addressed promptly. Major violations include circumvention attempts, unauthorized device removal, repeated rolling retest failures, or tampering with device seals. While minor violations might extend your program slightly, major violations can result in immediate license suspension and requirement to restart your entire program from the beginning.
Certified professionals help you avoid violations by maintaining your car breathalyzer to prevent malfunctions that trigger false failures, ensuring accurate calibrations so legitimate breath samples aren't rejected by the device, scheduling timely maintenance appointments that meet all state requirements, providing proper documentation for the Michigan Secretary of State, and answering questions about compliance requirements so you understand exactly what's expected throughout your program.
Attempting device maintenance yourself or trusting unqualified technicians creates serious risks. Car breathalyzer devices are sophisticated instruments requiring specific training, manufacturer-approved equipment, and deep knowledge of Michigan's compliance requirements. Mistakes aren't just inconvenient; they can result in program violations, extended requirements, or license revocation. Professional certification matters because certified technicians understand state compliance requirements and manufacturer specifications, have proper diagnostic equipment that ordinary shops lack, are trained on each specific device model and its unique requirements, maintain proper documentation protecting you if questions arise, and are accountable to manufacturers and the state for their workmanship.
