Ignition Interlock Installation: What Happens to My Car?

You’ve taken the important first step and made your appointment with LifeSafer for your ignition interlock installation. You are one step closer to unrestricted driving.  We know this is a stressful time and you don’t know exactly what to expect.  

To help you, here are some frequently asked questions and answers as to exactly what’s going to happen when you get to your Authorized LifeSafer Service Provider.


Q:   How long does an ignition interlock installation take?

Our expert technicians take the installation process very seriously.  To make sure your installation is complete and correct, plan to spend about 90 minutes from start to finish at the location. While your vehicle is being worked on, you will be asked to watch an important training video to help you get familiar with how your interlock works. We want you to feel comfortable with how to take a test to start the vehicle, to understand how to take a test while driving, and to be aware of any everyday items that you will want to avoid prior to taking a test.

Many LifeSafer locations offer drop-off service to make your ignition interlock installation more convenient. If you location offers drop-off,  you can leave your car and come back at the end of the day to collect it.


Q:   Will installing an interlock mess up the wiring of my car or interfere with other features I have?

Our technicians have a wiring diagram of your particular vehicle so they know exactly where to find the wires they need to install the device.  The wires needed are generally found within the cabin of the vehicle. Occasionally in newer vehicles, they are located under the hood. If so, the wires are delicately fed through an existing grommet or entry point in the vehicle’s firewall. The Ignition Interlock device and its components will always be housed safely in the cabin of the vehicle, out of view and protected from the elements.  There will be no drilling new holes in your vehicle.


Q:  What will people be able to see in my car?

You will only see the discrete black handset which you blow into and the “curly” wire that connects the handset to the rest of the device.  The other parts of your ignition interlock are safely tucked away, usually around the knee level panel of your vehicle.


Q: Will the non visible parts interfere with my safety features or steering wheel?

No.  They are located away from the steering columns and foot pedals to ensure the safe operation of your vehicle after the installation.
