ADS Interlock
Installer network under the Alcohol Detection Systems brand, part of the same group as Intoxalock.
Where ADS Interlock actually reaches
These figures come from our own index of 10,531 installation points, not from the brand’s marketing. A network is only useful if it reaches the town where you have to drive every 30 to 60 days for a calibration.
ADS Interlock appears at 502 of the 10,531 points we have on file — 5% of the market as we measure it — spread over 28 states and 451 towns and cities. 49% of those addresses also install a competitor’s device. That is worth knowing: the shop is not tied to one brand, so switching provider often does not mean switching garage.
In 53 of those towns it is the only installer on file. If you live in one of them, the price you are quoted is the price there is.
Not found in Alabama, Colorado, District of Columbia, Delaware, Georgia, Hawaii, Iowa, Idaho, Mississippi, Montana, North Carolina, North Dakota, New Hampshire, New York, Ohio, Rhode Island, South Dakota, Utah, Virginia, Washington, Wisconsin, West Virginia, Wyoming — if you are there, one of the other providers is your route.
What ADS Interlock costs
ADS 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.
ADS Interlock customer service and phone numbers
We are not ADS Interlock’s support desk and cannot see your account. These are the company’s own published lines, listed because they are unreasonably hard to find when a device has just locked you out.
customers and new enquiries
Only ADS Interlock can do these
- Billing disputes and the balance on your account
- A lockout code when the device will not let you start
- Booking or moving a calibration appointment
- The removal paperwork your state agency needs
- Anything the monitoring authority has already been told about your device
These we can help with
- Finding a certified center closer to you than the one you were assigned
- Checking what your state caps or requires, so you know what is negotiable
- Comparing what another approved provider charges before you commit

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.
