An INFINITI dealer can duplicate it. As many as 5 INFINITI Vehicle Immobilizer System keys can be used with one vehicle. You should bring all registered keys that you have to an 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.
