Not all breath alcohol ignition interlock devices are equal! Here are the important features that make the Intoxalock® one of the most affordable and reliable ignition interlock devices on the market today.

No False Readings

You will never be stranded because of a false-positive reading. A state-of-the-art, alcohol-specific fuel cell minimizes the likelihood of equipment failure, even under extreme temperatures or altitude. The Intoxalock® is widely regarded as the most accurate interlock device on the market today.

Full Recording Capabilities

The Intoxalock® records vehicle starts/stops, all test results, failed starts due to high readings, power failures and tampering attempts. This information is vital for court records and other legal documentation to assure compliance with state laws. In addition, the Intoxalock® features a rolling retest function that prevents a person from starting the vehicle sober and then consuming alcoholic beverages while driving.

LED Display

While most breath alcohol ignition interlock devices simply display red, yellow or green lights to signify results, the Intoxalock’s® eight-character LED display lets you know your exact breath alcohol content on the spot. (This feature is not available in all states.) For ease of operation, it also displays basic instructions.

Convenient Service Center Locations

The Intoxalock® can be installed and serviced in nearly 700 locations across the United States.

Convenient Calibration Services

In many states, ignition interlock devices must be calibrated every 60 days to assure they have not been tampered with or are malfunctioning. To save drive time and unnecessary time off work, CST, Inc. will ship you a new Intoxalock® device at your appointed recalibration time. You simply unplug the expiring unit, plug in the new unit and return the expiring one to our offices in Des Moines, Iowa.

Fast Repair Service

Repairs are handled through CST’s exclusive Direct Exchange Program. In most cases, non-functioning units can be repaired over the telephone. If a replacement is necessary, CST will have a new unit delivered within 24 hours.
