What to Expect
If you were arrested for a DUI or an APC in Oklahoma on or after 11/1/22, you are required to participate in the Impaired Driver Accountability Program (IDAP). If you successfully complete the program, the license revocation will not appear on your driving record and there will be no reinstatement fees! Under this program, you will have an ignition interlock device (IID) installed on any vehicle you drive and the interlock will stay on vehicle(s) for the same time period your license would be revoked.

Best interlock service with the least amount of hassle and least amount of fees! Definitely recommend!
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!
Compared to any other interlock provider, this place is the best hands down! Not only is it the best price, but they work hard to make sure you’re driving safely and legal. Anytime someone needs an interlock I send them here!

Great customer service, affordable and they get you in and out quick.
I came in expecting to get an interlock and Raven was 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!
This place is actually pretty awesome. Compared to other companies who charge twice as much for worse services!
This place is so clean and nice! All the workers are friendly and polite! Makes this much easier to want to do every month.
I was late for my reset appointment, I called and got there right at closing time. The guys were just extra amazingly fast and super friendly. They care and are there for you. I am VERY pleased with their service.
