NISSAN VEHICLE IMMOBILIZER SYSTEM KEYS You can only drive your vehicle using the master keys which are registered to the NISSAN Vehicle Immobilizer System components in your vehicle. The master key can be used for all the locks. Never leave these keys in the vehicle. Additional or replacement keys: If you still have a key, the key number is not necessary when you need extra NISSAN Vehicle Immobilizer System keys. Your dealer can duplicate your existing key. This is because the registration process will erase the memory of all key codes previously registered into the NISSAN Vehicle Immobilizer System. Do not allow the immobilizer system key, which contains an electrical transponder, to come into contact with water or salt water. This could affect system function. CAUTION Always carry the mechanical key installed in the Intelligent Key slot. Valet hand-off When you have to leave a key with a valet, give them the Intelligent Key itself and keep the mechanical key with you to protect your belongings.
