Nissan Intelligent Key® and Locking Functions allows you to lock or unlock doors, open the trunk and start the engine without removing the Intelligent Key from your pocket or purse. See the video below of the
2013 Nissan Altima Coupe's use of the Intelligent Key technology.
To unlock the vehicle, push this Request Switch on the door handle. That door will now unlock. Press the button again within five seconds and all doors will unlock. To lock your vehicle, push any door handle's Request Switch once after all the doors have been closed.
The trunk unlocks when you unlock all doors. To open the trunk, push this Opener Switch just above the license plate for more than one second. Lift the lid to open. These lock and unlock functions are operational when the Intelligent Key is within about 2 ½ feet of the corresponding request switch.
The Intelligent Key is also equipped with a remote system for operating door locks. It is possible to lock and unlock all doors and open the trunk, using your Intelligent Key from outside the vehicle, at a distance of up to 33 feet. To lock doors, press the LOCK button. Your hazard warning lights will flash twice, your horn will beep once, and you'll know that all doors are locked.
If you are near your vehicle and feel threatened, press this PANIC ALARM button for more than half a second. The panic alarm will sound and the headlights will stay on for 25 seconds. To turn OFF the panic alarm, press any button on the Intelligent Key.
