All depends on if you have the alarm. It's in there, but it may or may not be activated. Bring it to a hardware store and they can tell you. Do not ask Nissan. They tell everyone that every key needs to be programmed
There was a bunch of trucks that were supposed to have the system but it wasn't installed when built, those owners had to have the dealer put in the necessary parts.
If I recall correctly if you try a standard cut key more than a couple of times and it won't start the truck will think it's being tampered with or stolen and go into a fail safe mode and has to be towed to a dealer to reset it.
