Intoxalock device, company and complaints

Device
Its own site doesn't give the model a name: there's a plain device, or one with a camera plus real-time reporting.
Taking a test
Blow for one second, breathe in for one second, then keep blowing till the handset vibrates; that's about 4 seconds.
What it does
A one-button start; on the fuller device you also get real-time reporting, a camera and remote lockout clearing; a protection plan costs $10 a month.
Driver app
For calibration dates, payments and your account, there's the Intoxalock Mobile App.
Company
One of the Mindr brands, like ADS, is Consumer Safety Technology, LLC.
Also searched as
Intox a Lock
BBB rating
A+, accredited by the BBB (its Urbandale, Iowa listing).

Its BBB page lists the complaints and how the company replied. Sources: Intoxalock's app page, company details, device page and test guide, and Mindr's brand list.

From booking to removal with Intoxalock

  • Book the install: call 888-528-2919 or leave your number, and Intoxalock or another installer in your state sets a day.
  • The install happens at a service center. Each service center sets the price. The handset gets wired to your ignition before you drive off.
  • Your state sets the timing for calibration visits, every 30 to 90 days. Starting at $20 a visit.
  • Once your state clears you, the device comes off; here's how removal works.

The 12‑month column takes the listed lease for a full year, adds the install charge and includes any set‑up fee. If a company doesn't publish an install price, the column applies MADD's typical range (shown with *); when it publishes no price at all, the cell states that. Quoted by phone: you get the price when you call. MADD's general estimate, as a guide: $60 to $80 a month plus $70 to $150 to install, or about $790 to $1,110 over 12 months ($720 to $960 where installation is free).
