Where each company can install in Kansas
You'll go back to the same company's locations for service for the whole order, so check that one is close to where you live and work before you book.
Locations as each company lists them on its own locator (Smart Start, Intoxalock, LifeSafer, Low Cost Interlock), pulled Oct 2026. Some shops serve more than one company. Alcohol Detection Systems doesn't publish a locator we could read.

Questions about interlocks in Kansas
How long do you have to have an interlock in Kansas?

A first offense below 0.15 can mean 180 days or 1 year in listed circumstances, a first offense at 0.15 or higher means 1 year, and repeat offenses run from 1 to 10 years. Someone under a 10-year restriction may petition the district court for relief after 5 years.2
How much is the restricted license fee in Kansas?
The application fee is $100. The Division of Vehicles assesses it when you apply to modify your suspension, which is the step that gets you the restricted license that lets you drive a vehicle with an interlock. This fee is separate from whatever your device vendor charges for the device itself.6
