Wisconsin IID's Ignition Interlock Program

  • Free Installation: Free installation is available on most vehicles. More difficult installations may require up-charges on certain makes and models or given the presence of certain vehicle components such as remote starters and push button starters. You will only be charged for the added difficulty, and will still get a credit towards the cost of a standard installation.
  • Low Price Guarantee: We guarantee the lowest price in the Madison area. If you should discover some other offer from a certified WI IID provider, let us know and we will beat their price. This offer extends right up until the point of installation.
  • Superior Service: When you absolutely need an operational vehicle, Wisconsin Interlock is the best choice for a service provider. Wisconsin Interlock resides locally, does not subcontract its service, and only works with the interlock device, not other car accessories. Therefore all of our skill and knowledge results in better troubleshooting and quickly executed superior service should you have a problem with your device. YOU WILL NOT HAVE TO MAIL YOUR DEVICE TO A OUT-OF-STATE SERVICE PROVIDER IF SERVICE ISSUES SHOULD ARISE. We have diagnostic equipment and replacement devices on hand in Middleton to correct any device related problems, should any issues arise.
