Nissan Sentra Owners 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.
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 5 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.
Any key that is not given to your dealer at the time of registration will no longer be able to start your vehicle.
CAUTION
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.
