Intoxalock Review (2026): Published Prices, Fees & Who It’s Best For
Intoxalock is one of the largest interlock providers in the country, and its selling point is reach: it advertises more installation locations than any competitor, with same-day or next-day appointments in many areas. If you’re on a court deadline, that matters more than a few dollars a month. The trade-off is a fee structure with a lot of moving parts — worth reading before you sign.
Intoxalock’s network is its real advantage. If you need a device in the car this week, or you live somewhere with only one or two certified shops nearby, it’s usually the shortest path. If your only priority is the lowest total over a two-year term, get a second quote first — the published lease rates overlap heavily with competitors.

- Billing cadence — get it in writing. Some plans bill every two weeks, which is 26 payments a year, not 24
- Any monthly data or processing fee on top of the lease rate
- What the removal process and timing look like, and whether you’re charged for a full final month

- Roadside assistance is free for six months, then billed
- Deposits vary widely by state and aren’t always quoted upfront
How it works day to day
Testing
You provide a breath sample to start the car, then again at random intervals while driving. Failing multiple tests, or tampering, can require remote support to unlock the device — that’s the $75 lockout fee. Some failures are false positives from mouthwash, hand sanitiser or certain foods; if one happens, document it and call the same day.
Service centers and appointments
Installation is done at an independent certified service center, and you pay that shop directly. Expect the appointment to take a couple of hours. Calibration visits run every 30 to 90 days depending on your state, and missing one can put the device into lockout — book the next one before you leave.
End of term
Plan removal well ahead of your end date. Confirm with your state or court what proof they need, book the removal appointment early, and return the device to the installation center promptly — an unreturned device is charged at $2 per day.
Should you choose Intoxalock?
Is Intoxalock approved in your state?
Interlock certification is granted state by state, and a device approved in one state may not be approved next door. Check your state’s certified-vendor list before you sign anything — an unapproved device won’t satisfy your order.
