Removal – Submit removal request per your scheduled Ignition Interlock Program State Mandate

State Regulators, Courts and Judges mandate that all individuals in the DUI Ignition Interlock program be aware of their required/mandatory Calibration visits.  It is the responsibility of the individual in the Ignition Interlock program to know the date and schedule their Calibrations with their Service Center.  Do not rely solely on the device for your scheduling.  Any State Mandated Calibration visits missed will be documented and could cause an immediate suspension and arrest warrant issued (per your State Laws).  If you have requested a Calibration/Reset visit, your next Calibration Date will be on your signed Calibration/Reset authorization form. Utilize your State Mandated scheduling or the Service Center Calibration/Reset Authorization Form with your next Service Date to schedule your next required Calibration.  IMPORTANT! Please carefully read and make sure that the form is filled out completely.  Ask your Service Center for a copy of your Signed Calibration/Reset Service Center Authorization Form which will have your next required Calibration Date listed.  If you have any questions regarding the information contained on the Calibration/Reset authorization form, please contact Instant Interlock LLC at (800) 957-0036, Ext 4 for further assistance.
