“While it may not be the best experience having to have a Smart Start on your vehicle and it may make you feel pretty down – the folks that work for the company are always beyond helpful. Especially – shout out to Aaron – who has been going above and beyond for me to try to figure out a random “tamper” on my device. Try to treat these folks kindly when you call as, I’m guessing you’re not happy with having to deal with your device, but they are just doing their jobs and they are doing them well and with no judgment. Thanks, Smart Start. I appreciate your kindness.”
“Very nice people training was excellent. If I have questions they said please call.”
“I accidentally left my vehicle running while putting air in the tires last night, and missed a test on the device. I went straight to SmartStart in the morning and had the pleasure of meeting Dan who helped service my vehicle. Dan was helpful, knowledgable and not only patient with my questions, but also informative. Thank you for the great service!”
“I drive around 170 miles daily with a Smart Start device. As long as I have followed the instructions I was given I have never had an issue. Tech support always answers quickly, and I never felt like im bothering them, no matter how simple my question. The girls in call center and accounting are always such a pleasure when im making a payment. Be smart and think Smart Start.“
Frequently Asked Questions
Everything you need to know before, during, and after your installation.
How does an interlock device work?
An ignition interlock device is a breath-alcohol testing system installed in your vehicle that prevents it from starting if alcohol is detected. Before starting the car, you blow into the handset, and if no alcohol is present, the vehicle starts normally. While driving, the device may prompt you for periodic retests to ensure continued compliance, with enough time to safely pull over if needed. All test results are securely recorded and reported in accordance with Wisconsin Department of Transportation (WisDOT) requirements, helping you remain compliant while legally driving.
What is the cost of an interlock device
The cost of an ignition interlock device varies based on installation fees, monthly monitoring charges, and any required services or calibration visits, but with Smart Start Wisconsin you can expect a competitive, transparent pricing structure that typically includes an initial installation fee and a monthly rental/monitoring fee; additional costs may apply for periodic maintenance or calibration, and many courts or state programs allow payment plans or financial assistance for qualifying individuals — for exact pricing at your location, contact your local Smart Start Wisconsin service center for a personalized quote.
What happens if I fail a breath test on my ignition interlock device?
If you fail a breath test, your vehicle will not start and the event is recorded by the ignition interlock device. Under Wisconsin regulations, repeated failed tests may result in additional consequences, such as a temporary lockout or reporting to the Wisconsin Department of Transportation (WisDOT). Smart Start devices allow you to retest after a short waiting period once alcohol is no longer detected. Following Wisconsin’s ignition interlock guidelines is essential to remain compliant and avoid further penalties.
How often does my IID need to be serviced in Wisconsin?
In Wisconsin, ignition interlock devices typically must be serviced and calibrated every 30 to 60 days, depending on your court order and program requirements. During these service visits, Smart Start technicians download device data, perform calibration, and ensure the unit is functioning properly. Regular servicing is required by the Wisconsin Department of Transportation (WisDOT), and missing an appointment may result in a violation or additional penalties, so it’s important to stay on schedule with your assigned service location.
What should I do if my interlock device locks me out?
If your ignition interlock device locks you out, do not attempt to tamper with or remove the device. A lockout usually means the device requires service due to missed tests, failed tests, or a missed calibration appointment. Contact Smart Start Support at (888) 234-0198 as soon as possible. All lockout events are recorded and may be reported to the Wisconsin Department of Transportation (WisDOT), so addressing the issue promptly helps you remain compliant and avoid additional penalties or extensions of your interlock requirement.
What if the title of the vehicle is not in the client’s name? Can the device be installed/removed?
An interlock device can be installed in a vehicle that is not in the client’s name. If the owner (name on title) of the vehicle chooses to have the device removed from the vehicle we will remove the device. Unless the client is court ordered then court authorization is required.
