KEYS 5. Key number plate 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 INFINITI Vehicle Immobilizer System keys. Your dealer can duplicate your existing key. As many as five INFINITI Vehicle Immobilizer System keys can be used with one vehicle. You should bring all INFINITI Vehicle Immobilizer System keys that you have to your INFINITI dealer for registration. This is because the registration process will erase the memory of all key codes previously registered into the INFINITI Vehicle Immobilizer System. After the registration process, these components will only recognize keys coded into the INFINITI Vehicle Immobilizer System during registration. Any key that is not given to your dealer at the time of registration will no longer be able to start your vehicle. Do not allow the immobilizer system key, which contains an electrical transponder, to come into contact with salt water. This could affect system function. A key number plate is supplied with your keys. Record the key number and keep it in a safe place (such as your wallet), not in the vehicle. If you lose your keys, see an INFINITI dealer for duplicates by using the key number. INFINITI does not record key numbers so it is very important to keep track of your key number plate. A key number is only necessary when you have lost all keys and do not have one to duplicate from. If you still have a key, your INFINITI dealer can duplicate it. INFINITI VEHICLE IMMOBILIZER SYSTEM KEYS You can only drive your vehicle using the master or valet keys which are registered to the INFINITI 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. WPD0310 1. 2. 3. 4.
