* Look for the keyless entry button on the driver's door. This button is usually located near the door handle.
* Try to open the door without using the key. If the door opens without a key, then the car is equipped with keyless entry.
* Check the owner's manual. The owner's manual will state whether or not the car is equipped with keyless entry.
If you are still not sure whether or not your car is equipped with keyless entry, you can contact your local Nissan dealer.
