SYSTEM DESCRIPTION

• The Nissan Anti-Theft System (NATS) prevents the engine from being started by Intelligent Key whose ID is

not registered to the vehicle (BCM). It has higher protection against auto theft involving the duplication of
mechanical keys.

• The ignition key integrated in the Intelligent Key cannot start the engine. When the Intelligent Key battery is

discharged, the NATS ID verification is performed between the transponder integrated with Intelligent Key
and BCM via NATS antenna amp. when the Intelligent Key backside is contacted to push-button ignition
switch while brake pedal is depressed. If the verification result is OK, the engine start operation can be per-
formed by the push-button ignition switch operation.

• Locate the security indicator lamp and always blinks it when the ignition switch is in any position except ON

to warn that the vehicle is equipped with Nissan Anti-Theft System (NATS).

• Up to 4 Intelligent Keys can be registered (including the standard ignition key) upon request from the owner.
• When replacing ECM, BCM or Intelligent Key, the specified procedure (Initialization and registration) using

CONSULT is required.

PRECAUTIONS FOR KEY REGISTRATION

The ID registration is a procedure that erases the current NATS ID once, and then registers a new ID. There-
fore before starting the registration operation, collect all registered Intelligent Keys from the customer.
