The Real Cost of an Ignition Interlock in NH: One Year, Line by Line
One New Hampshire driver’s ignition interlock cost $2,551.38 from installation through removal for about a year, roughly $213 a month or $49 a week. When the driver kept the device for about 14 months, the total reached $2,933.24.
As of October 23, 2026. These figures come from one New Hampshire driver’s Intoxalock account statement and service-center invoices, with personal details removed. They describe one person’s experience, not official Intoxalock pricing. Costs can vary by provider, vehicle, program length, and individual circumstances. Chrysalis Recovery Center LLC does not sell or install ignition interlocks.
One year, line by line
This account covers installation in August 2025 through August 2026, including removal at the end of the period. The total combines one-time charges, recurring lease and processing fees, recalibration visits, and removal. It is not simply a monthly lease price.
| What was paid for | How often | Amount |
|---|---|---|
| Installation at the service center | Once | $375.00 |
| Device lease, first charge, shipping and setup fee | Once, at sign-up | $124.98 |
| Device lease, about every two weeks ($54.99 at first, then $56.98) | 25 charges | $1,404.60 |
| Monthly data processing fee | 6 times | $18.00 total |
| Data log fee | Once | $25.00 |
| Return shipping | Once | $40.00 |
| Recalibration visits at the service center | 7 visits at $25 | $175.00 |
| Removal: labor $360.00 plus shop supplies and hazmat $28.80 | Once | $388.80 |
| Total for one year | $2,551.38 |
The account summary estimated the lease alone at about $1,460 a year; the 25 recurring lease charges listed above totaled $1,404.60. The one-time installation was $375.00, and removal was $388.80. Those start-and-finish costs together came to $763.80.
What changed when the device stayed longer
The driver kept the device for about 14 months. Two additional months of charges and one more recalibration visit increased the total cost through removal to $2,933.24.
| Additional cost after the first 12 months | Amount |
|---|---|
| First 12 months, including removal charges listed above | $2,551.38 |
| Two extra months of lease charges | $290.87 |
| Data processing fees in the extra months | $6.00 |
| Admin closing fee | $59.99 |
| One more recalibration visit | $25.00 |
| Total, installation through removal | $2,933.24 |
The difference between the 12-month and 14-month totals is a useful reminder: the actual cost depends on how long the device remains installed and what charges apply during that time.
Budget for more than the recurring lease
An ignition interlock cost in NH may include several types of expenses. This driver’s account offers a practical example of what to ask about when reviewing a quote or planning ahead.
- Ask how the lease is billed and whether it may change. In this account, charges began at $54.99 and reached $58.97 by the last charges. A starting amount may not be the amount charged throughout the full period.
- Ask how often the vehicle needs recalibration. This driver had seven visits in the first year, generally every one to two months, at $25 per visit. Service-center schedules and fees may differ.
- Keep the account current. The account notes indicate that an unpaid balance can interrupt service at the next calibration. Confirm payment dates and what happens if a payment is missed.
- Plan for costs at the end, too. Removal and an admin closing fee were due as the program ended. Setting aside money for these charges early can make the final step easier to manage.
- Request a full written estimate. Ask the provider and service center to identify the lease, installation, shipping, processing, calibration, removal, and any other applicable fees. Confirm which costs recur and which are one-time charges.
How the interlock fits into the broader process
An ignition interlock is one possible expense in a New Hampshire DWI case, not the only one. Depending on your situation, you may also need to plan for an IDCMP evaluation, the 20-hour class, license-restoration steps, and possibly SR-22 insurance. Other expenses may apply to your case as well.
Requirements can differ. Do not assume that every driver has the same interlock requirement or timeline. Review your court documents and confirm your situation with the New Hampshire DMV. The NH DMV ignition interlock information is a useful place to start.
If your case includes a Victim Impact Panel (VIP), account for its separate cost and timing. Clients must complete the VIP before completing the IDCMP program at Chrysalis Recovery Center LLC. Clients must submit their own VIP completion certificate and SR-22 proof directly to the NH DMV for license reinstatement. Confirm with the DMV what documents are needed for your individual situation.

A real account statement can make planning more concrete, but your costs and requirements may be different.

A written estimate and clear information about your own case can help you plan with more confidence.
