Missouri Ignition Interlock Low Price Guarantee

If you are able to find an interlock device at a lower cost from any State of Missouri authorized vendor before your MIID installation date, we will beat their offer. If you are price shopping be sure to ask what total monthly charges would be (including recalibration service). This is the best way to compare apples to apples and if for some reason a competitor is offering a lower price, we will beat their offer.

Free Installation Offer

Free installations are available for most vehicles for a limited time. More difficult installations may require more time than typical installations and incur an upcharge based on the type of vehicle and vehicle components. These upcharges ,if necessary, will be explained to you prior to scheduling your appointment.

What To Expect At Your Installation Appointment:

  • A typical installation appointment takes 1 1/2 to 2 hours.
  • You will be trained on how to use the device while a certified ignition interlock service technician installs the IID.
  • You will need to complete the administrative paperwork.
  • You will receive proof of installation.
