QuickStart Interlock
Arizona-focused provider: listed on the state MVD register of authorized companies, fitting the QT2 device. Its own website was not responding when we checked.
What QuickStart Interlock costs
QuickStart Interlock does not publish a single national price, and quotes vary by state and by the center doing the install. We are collecting confirmed quotes and will publish them here with the date each one was checked — not before.
Where QuickStart Interlock is approved, and under which device
States publish their own lists of vendors allowed to fit an interlock, and the model name on that list is what your paperwork has to match. This is the one claim about a provider that does not come from the provider.
| State | Device on the state list | Who publishes it |
|---|---|---|
| Arizona | QT2 | Arizona Department of Transportation, Motor Vehicle Division · checked 2026-08-30 |
Approval in one state says nothing about the next one: each program keeps its own list, and a device accepted in Texas may not be accepted where you live. If you move mid-term, this is the first thing to check — before the provider tells you it is fine.
What using QuickStart Interlock actually means in those states
| State | Term on a first offence | What the state publishes on price | Certified centers we index there |
|---|---|---|---|
| Arizona | At least 12 months on a standard first conviction; longer at higher readings — 12 months for Extreme DUI at 0.15%, 18 months for Super Extreme at 0.20% (A.R.S. 28-1382) | Nothing published | 346 |
The last column is the honest context for a small brand: where the state has hundreds of certified points, being on the approved list is a starting position rather than a reason to choose. Where a state caps the monthly fee, the price argument disappears entirely and the only question left is the drive to calibration.
Check the register yourself before you pay
We verified the entries above on the dates shown, and state lists change without notice. For a provider this small the register is the whole of the evidence, so it is worth thirty seconds:
- Arizona — Arizona Department of Transportation, MVD. Provider, phone and the exact device model each one is authorized to fit.
If the name is gone from the list, that is not a paperwork problem: time on an unapproved device does not count toward your term, and the months are the expensive part.
Compare before you commit
Providers rarely differ enough on the device to matter. The difference you feel is the monthly fee, the lockout policy, and how far you drive every 30 to 60 days for a calibration.
