I need your assistance!! I have a 1999 Infiniti G20 and I was putting my other car keys in the ignition by accident and then when I put the correct car keys in, the car would not start. I googled info on the safety features and I found that Infiniti's come with a Vehicle Immobilizer System/Nissan Anti-Theft System. What I cant find out is how to re-set it. All I know is that the keys need to be reset but I want to know if I could do it myself or do I have to take it to a shop. I am asking you since I know you had a Nissan Maxima and I dont know if you pulled this stupid move like me or not.
