CAUTION Always carry the mechanical key installed in the Intelligent Key slot. 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 salt water. This could affect system function.

To prevent the glove box and the trunk from being opened during valet hand-off, follow the procedures below: SPA1951 1. Push the trunk cancel switch to the OFF position. 2. Remove the mechanical key from the Intelligent Key. 3. Lock the glove box and the rear seats with the mechanical key. 4. Hand the Intelligent Key to the valet and keep the mechanical key with you.
