To reset the security system on a 1990 Nissan 300ZX, you can try the following steps:

Close all the doors and ensure they are securely shut.

Insert the key into the driver's side door lock.

Turn the key counterclockwise to unlock the door, and then clockwise to lock it again.

Repeat the process of turning the key counterclockwise to unlock and clockwise to lock three times. Make sure to complete this sequence within a few seconds.

After the third cycle, open the driver's side door and enter the vehicle.

Insert the key into the ignition and turn it to the "On" position without starting the engine. Leave it in this position for about 15 minutes.

After the 15 minutes have passed, turn the ignition key back to the "Off" position.

Start the engine to see if the security system has been reset. The security light should stop flashing or remain off.

If the above steps don't work or the security system continues to cause issues, it's recommended to consult the owner's manual for specific instructions or contact a Nissan dealership or a qualified automotive technician for further assistance. They will have the expertise and access to the necessary resources to help you reset the security system on your 1990 Nissan 300ZX.

The trunk open and close with the key is the factory way. Done it dozens and dozens of times.
