Ignition Interlock Installation Process Explained

If you have been mandated to install an interlock following a DUI incident, you will need to visit a state-approved interlock provider. State-approved providers meet all state criteria and also work with state monitoring authorities.

How Long Does It Take To Install an Interlock?

State monitoring authorities gather the testing data from interlock devices and use it to monitor the offenders. They receive reports of failed tests and attempts to tamper with the device. Some states have compliance-based interlock policies, and repeated failures or attempts to tamper can result in the interlock term being lengthened, plus additional legal penalties. 


After you choose your interlock provider and make your installation appointment, this is what you can expect: 

  • First, you will show the interlock provider the necessary paperwork and identification.
  • They will install the device. The amount of time can vary depending on the make, model, and year of your car, but typically takes about an hour.
  • Then, the technician will show you how the device works and provide you with your certificate of installation, which may be required to obtain your driving privileges.
  • You will need to return on a regular basis for calibration. It varies by state, but typically calibration is needed every 30 to 90 days.


It’s important to visit a certified technician, because they will be able to install the device without damaging your vehicle.
