About Wisconsin Interlock


Most OWI convictions will require installation of the ignition interlock device in order to reinstate driving privileges in the state of Wisconsin. Wisconsin Ignition Interlock is a local installer and service provider of the Draeger XT ignition interlock device, an interlock device approved for use in the state of Wisconsin. The Draeger XT meets all State of Wisconsin ignition interlock device requirements, while offering the greatest ease of use.



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 pushbutton starters.  You will only be charged for the added diffiiculty, 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. 
    • Mobile Service:  We provide mobile service at an additional charge in Madison and throughout Dane County.




    • Ease Of Use - No Humming Required!
    • Operating Temperature Compatible With Wisconsin Winters (-40 to 145 degree temperatures).
