What it costs in Massachusetts
Published starting prices
| Provider | Install | Monthly lease | Calibration | Removal | 6 month floor | 12 month floor |
|---|---|---|---|---|---|---|
| Intoxalock | $29.99 | $49.99 to $95.99 | Not published | Not published | from $330* | from $630* |
| LifeSafer | Not published | $90 | Not published | Not published | from $540* | from $1,080* |
These are the lowest figures each provider publishes, so the 6 and 12 month totals are a floor, not a quote. They add the install fee, the monthly lease, calibration visits and removal where published. An asterisk means a fee is not published and is not included. Per day rates are counted as 30 days a month.
- Intoxalock: provider published intoxalock.com/state-requirements/massachusetts, October 27, 2026
- LifeSafer: provider published lifesafer.com/massachusetts/pricing, October 27, 2026
Reported totals usually run two to three times the published floor. Calibration visits, device protection, data fees and missed-appointment charges are rarely in the headline price.
