NOTE:
If customer reports a "No start" condition, request ALL KEYS to be brought to a Nissan dealer in case of a NATS malfunction.
NATS (Nissan Anti-Theft System) has the following functions:
- NATS shows a higher anti-theft performance at preventing engine to be started by an unregistered key. (registered key: mechanical key and Intelligent Key).
- Only a key with key ID registered in BCM and ECM can start engine, it has a higher protection against auto theft that duplicates keys.
- If a malfunction has been detected, security indicator will illuminate when ignition switch is in ON position.
- If the owner requires, mechanical key can be registered for up to 5 keys.
- During trouble diagnosis or when the following parts have been replaced, and if mechanical key is added, registration* is required.
*: All mechanical keys of the vehicle should be registered.
- ECM
- BCM
- Mechanical key
- NATS trouble diagnosis, system initialization and additional registration of other NATS mechanical key IDs must be carried out using CONSULT-III hardware and CONSULT-III NATS software. When NATS initialization has been completed, the ID of the inserted mechanical key can be displayed.
Regarding the procedures of NATS initialization and mechanical key ID registration, refer to CONSULT-III operation manual NATS.

SECURITY INDICATOR
- Forewarns that the vehicle is equipped with NATS.
- Security indicator will not blink while the ignition knob is in ON or START state.

NOTE:
Because security indicator is highly efficient, the battery is barely affected.

Condition of Security Indicator
- When operating the ignition switch with Intelligent Key, security indicator lamp will turn off at once if ignition switch is pressed and blinks when ignition switch is released.
- When operating the ignition switch with mechanical key security indicator will turn off at once if mechanical key is inserted into key cylinder and blinks when mechanical key is removed.
(Once the mechanical key is inserted into key cylinder, BCM will only perform the key ID verification with mechanical key)
