Car Alarms: 1992 Factory installed alarm going off, alternate side parking, silver dots

Question
I have a 1992 Nissan Maxima, and right now as I open my front left door with the key the factory installed alarm goes off.  Headlights flashing and horn blaring for two minutes.  I do have an aftermarket alarm but that is not the one making the noise.  I tried doing what you have suggested to one owner of a 1993 Maxima but it didn't work.

Usually, I could open the other 3 doors with the same key by just moving the key twice to the left, but as of right now that isn't working.

When everything seems fine, sometimes my automatic door lock does not lock the other 3 doors.

How can I fix my problem?  HELP!  Tomorrow I have to move my car as I live in NYC and we have alternate side parking street rules.  Your help is very appreciated.

Answer
To disable it totally requires you get up into
the under cavity, below the steering column, and
locate the anti theft warning module, to the left
of the steering column, and splice into the
factory disarm wire. a lt.green/black with
silver dots |- |, then ground it to the body
of the car permanantly.

That will take care of your
factory system alltogether.

I hope this helps. Good luck with it.
