S (Nissan Vehicle Immobilizer System-NATS) has the following immobilizer functions:
Since only NVIS (NATS) ignition keys, whose ID nos. have been registered into the ECM and IMMU of NVIS (NATS), allow the engine to run, operation of a stolen vehicle without a NVIS (NATS) registered key is prevented by NVIS (NATS). That is to say, NVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS (NATS).
All of the originally supplied ignition key IDs have been NVIS (NATS) registered. If requested by the vehicle owner, a maximum of five key IDs can be registered into the NVIS (NATS) components.
The security indicator lamp blinks when the ignition switch is in "OFF" or "ACC" position. Therefore, NVIS (NATS) warns outsiders that the vehicle is equipped with the system.
When NVIS (NATS) detects trouble, the security indicator lamp lights up while ignition key is in the "ON" position.
NVIS (NATS) trouble diagnoses, system initialization and additional registration for other NVIS (NATS) ignition key IDs must be carried out using CONSULT-II hardware and CONSULT-II NVIS (NATS) software. Regarding the procedures for NVIS (NATS) initialization and NVIS (NATS) ignition key ID registration, refer to CONSULT-II OPERATION MANUAL IVIS/NVIS.
When servicing a malfunction of the NVIS (indicated by lighting up of Security Indicator Lamp) or registering another NVIS ignition key ID no., it is necessary to re-register original key identification. Therefore, be sure to receive ALL KEYS from vehicle owner. System Composition NIEL0174 The immobilizer function of the NVIS (NATS) consists of the following:

Try disconnect negative battery cable for 10 seconds, then reconnect. In my case, after leaving lights on and draining battery, power locks on 2001 Sentra were not working, neither with remote fob or inside car. I have no idea why, but with above procedure, everything now works fine.
