How does an ignition interlock device work?

The device requires a breath sample before the engine will start, and it will not allow ignition if it detects alcohol above the set limit. It also asks for occasional rolling retests while you drive to confirm continued sobriety.

How often does the device need calibration?

Most programs require calibration roughly every 60 days, though your exact schedule depends on your state and case. We perform the service quickly, download the necessary data, and keep you on track so you never miss a required visit.

What is a rolling retest?

A rolling retest is a breath sample the device requests at random while you are already driving. It confirms you remain sober throughout the trip, and you simply pull the sample when prompted, so no single test covers the whole journey.

Will the interlock damage my vehicle?

No. At Audio Lab in Marysville, WA, we wire the device carefully and remove it cleanly when your term ends, restoring the original wiring, so your vehicle is left exactly as it was before the device was ever installed.

What happens if I fail a breath test?

The vehicle will not start, and the event is recorded for your monitoring authority. Waiting a short period and providing a clean sample usually allows a start, but repeated failures can affect your program, so understanding the rules matters.

Can food or mouthwash cause a false reading?

They can, because some products contain alcohol that lingers briefly in your mouth. We teach you to rinse with water and wait before testing, simple habits that prevent most false positives and keep your record clean and accurate.

Can I have the device installed on more than one car?

Yes. Drivers who operate multiple vehicles need a device in each, and Audio Lab installs and services them throughout Marysville, WA, aligning the calibration schedules so keeping several units compliant stays organized and easy for you to manage.

What happens when my interlock requirement is over?

Once your monitoring authority clears you, we remove the device and return your vehicle's wiring to its original state. The removal is fast and clean, and we make sure everything functions normally before you drive away without it.
