Hey Chan, in the same category of "because they can" when you buy a new remote for a Nissan, the dealership charges $120 to program your vehicle to accept the new remote. A disgruntled Nissan mechanic finally leaked the previously secret procedure to the internet and it is nothing more than a sequence of inserting your key in the ignition several times in quick succession, turning the ignition lock, and then pressing a button on the remote.
"You may experience some rectal pressure but that is normal and expected. Thanks for visiting your Nissan dealer and have a great day".
"If you come to a fork in the road, take it."
