CAUTION Always carry the mechanical key installed in the Intelligent Key slot. See "Doors" in this section and "Storage" in the "Instruments and controls" section of this manual. 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. These keys have a transponder chip in the key head. The master key can be used for all the locks. To protect belongings when you leave a key with someone, give them the Intelligent Key only, not the mechanical key. 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. As many as four NISSAN Vehicle Immobilizer System keys can be used with one vehicle. You should bring all NISSAN Vehicle Immobilizer System keys that you have to your NISSAN dealer for registration. This is because the registration process will erase the memory of all key codes previously registered into the NISSAN Vehicle Immobilizer System. After the registration process, these components will only recognize keys coded into the NISSAN Vehicle Immobilizer System during registration. 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. To prevent the glove box and the trunk from being opened during valet hand-off, follow the procedures below. 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 trunk passthrough with the mechanical key. 4. Hand the Intelligent Key to the valet and keep the mechanical key with you. See "Trunk lid" in this section, "Storage" in the "Instruments and controls" section and "Seats" in the "Safety - seats, seat belts and supplemental restraint system" section of this manual. SPA1951 Mechanical key The Intelligent Key contains the mechanical key, which can be used in case of a discharged battery. To remove the mechanical key, release the lock knob on the back of the Intelligent Key.
