What Is An Interlock?
An ignition interlock device (IID) is a breathalyzer connected to your vehicle's ignition. Before your engine starts, you provide a breath sample. If no alcohol is detected, the vehicle starts normally. The device is compact, discreet, and professionally installed.
Courts and the Oklahoma Department of Public Safety (DPS) may require an IID as a condition of license reinstatement following a DUI or DWI. If you've received an order requiring an interlock, we're here to help you get compliant quickly and professionally.
Before starting your vehicle, you blow into the device. While driving, the device may request rolling retests at random intervals. All data is recorded and submitted to DPS at your monitoring appointments. We handle the reporting on your behalf.

Oklahoma Interlock Program
Oklahoma law requires the installation of an ignition interlock device (IID) for individuals convicted of DUI or DWI offenses as a condition of driver's license reinstatement. The program is administered by the Oklahoma Department of Public Safety (DPS).
Participants must use a DPS-approved interlock provider throughout their required program period — typically ranging from several months to multiple years depending on the offense. Monitoring reports must be submitted regularly to DPS to maintain compliance.
Guardian Interlock is a DPS-approved provider in the state of Oklahoma. High Volume Car Stereo is your locally certified Guardian franchise in the Lawton area, serving Comanche County and surrounding communities.
