About Us

At Guardian Interlock, our mission is to get you back on the road again, all while offering the best price possible and unparalleled service.

Locally Owned & Operated

We are the only 100% Oklahoma owned and operated interlock provider in the state of Oklahoma. Which means you get the one-on-one attention and customer service you deserve. No corporate run around or additional hidden fees charged by another party like some ignition interlock companies charge. We are upfront and at your service whether that’s at the time of your installation or when you are on the side of the road and in need of assistance.

Our Device

The Guardian ignition interlock device can get you back onto the road safely and legally after a DUI arrest. The device is a breath analyzer that is attached to the ignition system of your vehicle to help you complete the IDAP Program.

In order to start your vehicle, you must first blow into the device. The device’s sensors will determine if your blood alcohol concentration (BAC) is low enough to start your car. If your BAC is too high, the device prevents your vehicle from starting.

Our device is the best interlock device available, with the latest fuel cell alcohol-specific technology to ensure the most accurate test results. It is also the smallest and most discreet device on the market! And it even has a removable handset that can act as an additional vehicle anti-theft device.

Brandon H, Tulsa

I had an appointment and Raven was incredibly helpful and selfless. She found out for me that I didn’t even have to have an interlock. Guardian was the only one to do this for me. They saved me almost $2000 over the next year and a half!

Simon R, Tulsa

I came in expecting to get an interlock and they were so helpful. She asked if I was sure I needed one because some laws changed. She spent 2 hours on the phone trying to get a hold of DPS for me. Turns out I didn’t have to have one! I’ve never had someone be so helpful!
