2014 Maxima Intelligent Key reset
 

Aftermarket intel key stopped working. Changed out the battery (CR2032) twice and still no good. Stand next to the car with the intel key and press the button on the door handle to unlock the car. I step on the brake and press the start button, car does not start. I place the intel key in the slot to the left of the steering wheel, step on the brake and push "Start". Car turns over-beautiful. I turn it off and remove the intel key from the slot. Now I press "start" w/o intel key in slot and car turns over!! All buttons on intel key work again. Hope this helps someone.
