What does interlock installation involve?

When you are ready to install, you’ll make an appointment at your local service center. Installation can take 1-2 hours, and it’s important to visit a certified installation center. Providers partner with these locations to ensure that the devices are installed correctly and can be monitored by the state. At a certified center, the skilled professionals who will work on your vehicle are specifically trained in installing interlock devices.  

Depending on the type of vehicle, installation may take longer in order for them to customize the installation to your vehicle - this is safest for your vehicle and you as you use the device. The technician will show you how the device works and provide a certificate of installation for your records.

How does interlock removal work?

When your interlock term is up, you will have to visit your service center location to have the device removed. 

Removing your ignition interlock or breathalyzer device can be easy. Notify your device provider in advance in order for them to schedule your removal. You will want to check the details of your court order and verify with monitoring authorities in your state before removing your device. They will confirm it is allowed and provide the date you can remove the device.  

It is necessary to have this information at your appointment, because all ignition interlock companies are required to have all of the state information and documents needed before they will remove the device. 

Can I keep my interlock device after my term is over?

Yes, you may choose to keep the device on a voluntary basis if you feel you are still at risk of drinking and driving or a repeat offense. Talk to your provider in order to find out what might work best for you. Intoxalock offers voluntary ignition interlock devices at a lower cost to customers who choose to have them.
