Deactivating the horn feature does not silence the horn if the alarm is triggered. If the system does not operate as described above, have it checked by a NISSAN dealer. If the no start condition re-occurs, NISSAN recommends placing the registered NVIS key on a separate key ring to avoid interference from other devices.
