Avoiding problems with your interlock- frequently asked questions after your device has been installed:

I thought the device was calibrated every 60 days?  It has only been 30 days and my device is saying that it needs service.  Why is this?

Your device is typically calibrated for 30 days after installation and then calibrated every 60 days thereafter if you make a payment for 60 days. 60 days is the maximum that the device can be recalibrated for by WI State law.

What happens during recalibration?

We download your device information and send it to our manufacturer, where government officials can obtain your records of compliance.

When do I pay?  Do I get a bill?

Normally you will make payment at the time of recalibration service.

I can’t blow into the interlock device or it seems obstructed.  What is the problem?

The mouthpiece is very likely stuck.  Try washing it or letting it soak in warm water and dish soap.  Let it dry and replace it into the handset.  If you are still having problems, request a new mouthpiece.

How often does the device ask for a test?

The tests are random and the parameters are the same no matter what manufacturer’s interlock device you use.

I have to get service done on my car, are they going to have to blow into it?

They can either blow in it, or you can have your mechanic contact Wisconsin Interlock’s customer service and obtain a code to over-ride the system.

My device says “lock out” in X number of days.  Why is it saying that? What do I need to do?

You have caused a violation and put the device in “lock out mode.”   This means you need to have service on the device within the day countdown period or your car will not start after this period of time.

What causes “lock out" mode and how do I prevent it from happening?

Three consecutive failed tests can cause you to go into "lock out" mode.  Failed tests are caused by failure to blow properly due to an obstructed mouth piece, failure to take a test when prompted while the vehicle is running, battery failure, tampering with the device, failure to recalibrate on time when prompted by your device , and failures due to alcohol present tests.  All of these can lead to lockout and a charge of $50.00 plus tax.

What happens if I don’t recalibrate?

Your device will go into” lock out mode” and after a week in” lock out mode” the vehicle will no longer start.  You will continue to be charged for leasing the device.  If you refuse to obtain service, the Sheriff’s office will be contacted regarding your noncompliance.

What form do I use to obtain my occupational license?

Form 3598 is used as proof at the DOT that your device has been installed.  Take the form along with any other paperwork that you may need to prove your compliance with the ignition interlock law.  Form 3598 will be given to you at the time of installation.
