    They will tell you it won't mess your car up. I'd suggest googling the thousands of people who's cars got messed up from it. Count me as your first. If anyone knows of mechanics that specifically fix interlock mess ups, please let us know. Thanks

    The guys at Draeger Alexandria are awesome. They are nothing but professional and courteous!! I was approved for early removal of my interlock and was going to have to go to Springfield location to have my device removed since Alexandria doesnt perform removals in the afternoon. As I was at the Alexandria location getting my last calibration i mentioned to Cesar, the technition that i was going to Springfield on Tuesday to get my device removed. He told me that the install in front of me didnt take as long as expected and told me that he could remove my device today. Totally unexpected but very much appreciated!! If you have to get an interlock device go to these guys in Alexandria they are awesome!!

    Caesar and Soon are awesome!! They squeezed me in within 30 minutes of my dealership missing a blow during my car servicing!! I was in a panic and they took care of me. They always accommodated my schedule and were right on time every time I arrived. They answered all my questions and always had great attitudes!!

Frequently Asked Questions About RoadGuard Ignition Interlock

How does an interlock device work?

When you start your vehicle, you have to blow into a mouthpiece that’s connected to the ignition interlock device, sometimes called an in-car breathalyzer. The interlock device will then measure your breath alcohol concentration (BrAC) and automatically determine whether your BrAC is low enough to allow the car to start. Any test you take, whether pass or fail, will be reported to your monitoring authority.

How much does an ignition interlock device cost?

Ignition interlock device costs vary because each state has different pricing regulations and device technology requirements. But in general, you can expect to pay between $50 and $150 to install the interlock device depending on vehicle type. After the initial interlock installation, you are required to pay a monthly rental or lease fee. On average, the cost to rent or lease an interlock device is between $50 and $150 per month.
