When customers come to Interlock of St. Louis they are trained on the proper use of an ignition interlock and the parameters of the program as established by the Missouri Department of Transportation.

We schedule service appointments for calibration of the device, data download and forward a summary report to the appropriate monitoring authority within 24 hours. Records are kept on permanent file for future inquiries.

Once you are ready we will schedule an installation at a convenient time.

*Customers not mandated by the courts are also welcome.
