A: Every manufacturer has different means of programming for a replacement remote. The Nissan dealer has a choice of using a computer scan tool known as the Consult-II or the conventional method that you can do yourself. It's not too tough as long as you're using the correct remote. Get in the vehicle. Close and lock all doors utilizing the driver's power-door lock/unlock switch. Insert and remove the ignition key more than six times within a 10-second period (at a rate of one insertion/removal cycle per second). Don't rush the process, and be sure the key is completely withdrawn from the ignition-key cylinder each time it's removed. Turn the ignition to the ACC position and press any button on the remote one time. The hazard lights should flash twice, letting you know your mission is a success. If you were going to program more than one remote, you'd simply unlock and lock the doors once again with the driver's switch and press the one button, one time, on the second remote. The procedure is completed by turning the ignition off, unlocking with the driver's switch, and opening the driver's door.
