1999 Nissan Maxima GXE 6 Cyl 3.0L
1999 Nissan Maxima wont start and security light wont stop blinking. How do I reset or disable the security system
If the security light comes ON with the key ON and/or while cranking, it is an immobilizer system lock-out. There is a TSB (NTB00-019) for updated Engine Control Module (ECM) and if that has already been updated, for an updated NATS immobilizer control unit. The system will need to be programmed either by a locksmith or factory scan tool.
