I have a 2011 maxima with remote entry and push button start in car and now 4 times not only to me but to my husband the car started with us just stepping foot in car not touching anything and the car also just started when we were walking away as well today ... We got it from Nissan dealer and no aftermarket alarms Nissan keyless entry and you have to push the button in car to start it ... So can someone please explain what is going on
