If you've been convicted of a DUI in Idaho and are required to install and use an ignition interlock device, you probably have plenty of questions. You could be wondering how do they work, where you can get it installed, and where do you even begin? Let's take a look at some of these questions and see how Naylor's Auto Repair can help guide you today.

Do I Need to Maintain My Ignition Interlock Device?

An ignition interlock device has a breathalyzer unit that you must blow into to start your vehicle and also randomly while you are driving. Your ignition interlock will require re-calibration to stay compliant. Naylor's Auto Repair knows calibration and re-calibration well and is available to help you with this process.

Also, it can be challenging to have your car repaired by a mechanic who isn't familiar with an ignition interlock device. You can know that bringing your vehicle to Naylor's Auto Repair is easier with the device, and it won't cost more to do an oil change, routine maintenance, or other repairs with the breathalyzer.

How Does Installation Work?

Naylor's will work with you on the installation of your device, as a certified Intoxalock Ignition Interlock location. The team at Naylor's will install and then remove the device once you've completed the terms of your license restriction or sentence.


Many issues begin with ignition interlock devices that are poorly maintained or ignored. While it may not be the most fun device to have, if you take care of it a bit, it will work better and allow you to continue your life without hassle.

A few issues occur when the device is dirty, stored on the seat or floor, used incorrectly, or not serviced as needed. The best way to stay ahead of these problems is to prevent them.


You can follow these steps to prevent more significant issues, frustration, or impacts on your work or life.

  1. Do your research—you should learn more about how ignition interlock devices work to streamline your use. Read all warnings and recommendations from the manufacturer. Understand the device's functionality and the legal requirements around its use. 

  2. Keep the device clean and dry using only a dampened cloth. Changing out the mouthpieces regularly is a good idea, so keep extras on hand. 

  3. Call a service technician for assistance in fixing your device, this will help to prevent concerns of tampering. If anything goes wrong or seems to be wrong, get help from a certified technician ASAP.

  4. Store the device in the holder to protect it from damage. Don't leave the device on the seat or the floor, especially not while you're driving. 

  5. Be careful and conscientious when using the device, this includes pulling over to perform any retests.

  6. Don't eat, drink, or use tobacco prior to using the device. Certain things can cause false positives or cause the device to malfunction. Plan ahead before driving, and remember that retesting occurs at random intervals.
