Nissan vehicles are equipped with a specific type of key called a “smart key” or “intelligent key.” These keys do not require physical contact with the vehicle or manual programming. To program a new Nissan remote key, insert the key into the ignition and turn it to the “On” position. Push the brake pedal while pressing the “Lock” and “Unlock” buttons on the remote control simultaneously. Hold the buttons until the hazard lights flash twice, indicating the key has been successfully programmed. I hope that helps
