A fault that blocks a compliance check needs rapid handling: record the fault code, the device serial, and the timestamp of the last successful pass, then request a prioritized device swap or in-person service to meet your appointment. Submit those facts at https://intoxalock.pissedconsumer.com/review.html and ask for confirmation of replacement timing so you avoid penalties. Request a clear pickup or delivery window and a single case contact for updates. Please request a single confirmation and a concise timeframe so progress is visible while support works the case.
