I have had my interlock for a little over a month…. The first month, no problems…the last two weeks….nightmare. I have electrical issues with my car. My battery boiled over and almost exploded…. I don’t think my interlock is installed correctly. What should nornally occur when you try to start your car without turning on the interlock? (my system says “TURN THE IGNITION OFF NOW”. BUT, if I don’t plug the handset in at all, I can start the car and drive it with no issues.
One would assume that if you can drive the car without the handset then it is wired incorrectly.
Call them back up and have them re-do it. Dont want to take a chance getting caught without the handset.
