      I felt compassion and empathy as well as a mutual trust that even though this is going to be expensive and costly, I am taken care of. Competitors treated me as though I didn’t have options... What a wonderful company and staff. Intoxalock should be proud.

      I currently use a different company for my interlock services and have been having nonstop issues... so I decided to switch providers. I explained this to the customer service rep who took my call... She was able to answer all my questions and get me setup to start new services immediately.

      FAQs: We’re Here to Answer Your Questions

      What is an ignition interlock device (IID)?

      An ignition interlock device (IID) is a car breathalyzer system installed in your vehicle to prevent a car from starting if alcohol is detected on the driver’s breath and may be required following a DUI violation. The IID device includes a mouthpiece for breath sampling, a handheld unit that measures breath alcohol content (BrAC), and a cord connecting the system to your vehicle’s ignition.
